Image to image translation conditional

The GAN objective is also mixed with a more traditional loss, based on L1 distance. “The discriminator’s job remains unchanged, but the generator is tasked to not only fool the discriminator but also to be near the ground truth output in an (L1) sense.”The translation results of face-to-face, edges-to-bags and edges-to-shoes are shown in Figure 3-5 respectively.

Don't use a JPEG whe Image-to-image translation tasks have been widely investigated with Generative Adversarial Networks (GANs) and dual learning. However, existing models lack the ability to control the translated results in the target domain and their results usually lack of diversity in the sense that a fixed image usually leads to (almost) deterministic translation result. In this paper, we study a new problem, conditional image-to-image translation, which is to translate an image from the source domain to the target domain conditioned on a given image in the target domain. It requires that the generated image should inherit some domain-specific features of the conditional image from the target domain. Therefore, changing the conditional image in the target domain will lead to diverse translation results for a fixed input image from the source domain, and therefore the conditional input image helps to control the translation results. We tackle this problem with unpaired data based on GANs and dual learning. We twist two conditional translation models (one translation from A domain to B domain, and the other one from B domain to A domain) together for inputs combination and reconstruction while preserving domain independent features. We carry out experiments on men’s faces from-to women’s faces translation and edges to shoes&bags translations. The results demonstrate the effectiveness of our proposed method.

In many image-to-image translation problems there is a a lot of low level information shared between the input and the output, and we’d like to be able to take advantage of this more directly.

The encoders serve as feature extractors, which take an image as input and output the two kinds of features, domain-independent features and domain-specific features, with the corresponding modules in the encoders. In particular, given two images xA and xB, we have

High level approach: GANs and cGANs

We first define some notations. Suppose there are two image domains DA and DB. Following the implicit assumption, an image xA∈DA can be represented as xA=xiA⊕xsA, where xiA’s are domain-independent features, xsA’s are domain-specific features, and ⊕ is the operator that can merge the two kinds of features into a complete image. Similarly, for an image xB∈DB, we have xB=xiB⊕xsB. Take the images in Figure 1 as examples: (1) If the two domains are man’s and woman’s photos, the domain-independent features are individual facial organs like eyes and mouths and the domain-specific features are beard and hair style. (2) If the two domains are real bags and the edges of bags, the domain-independent features are exactly the edges of bags themselves, and the domain-specific are the colors and textures. Pix2pix can produce effective results with way fewer training images, and much less training time, than I would have imagined.

We investigate conditional adversarial networks as a general-purpose solution to image-to-image translation problems. These networks not only learn the mapping from input image to output image, but also learn a loss function to train this mapping. This makes it possible to apply the same generic approach to problems that traditionally would require very different loss formulations… As a community, we no longer hand-engineer our mapping functions, and this work suggests we can achieve reasonable results without hand-engineering our loss functions either.

Pix2pix learns a mapping from input The pix2pix network was first introduced in the paper titled Image-to-Image Translation with Conditional Adversarial Networks, by Phillip Isola..

This works well for creating realistic images that are representative of the target class (by mapping from a random noise vector), but for image-to-image translation tasks we don’t want just any realistic looking image, we want one that is the translation of an input image. Such a network is said to be conditioned on the input image, and the result is called a conditional GAN or cGAN. The generator network is given both an observed image and a random noise vector as input, and learns to create images that the discriminator cannot tell apart from genuine translations of the input. Thus we need to collect (image, translation) pairs for training. Here’s an example where the input is a map, and the output is an aerial photo of area shown in the map.DualGAN-c. In order to enable DualGAN to utilize conditional input, we design a network as DualGAN-c. The main difference between DualGAN and DualGAN-c is that DualGAN-c translates the target outputs as Eqn.(3,4), and reconstructs inputs as ^xA=gA(eB(xAB)) and ^xB=gB(eA(xBA)). Image-to-image translation can be applied to a wide range of applications: generating photos by a Here are well-known pix2pix (paper: Image-to-Image Translation with Conditional Adversarial A GAN called UNIT (paper: UNsupervised Image-to-image Translation Networks) can be trained in an..

We demonstrate that this approach is effective at synthesizing photos from label maps, reconstructing objects from edge maps, and colorizing images, among other tasks

Conditional Image-to-Image Translation

The basic structure of the network is an encoder-decoder: the input passes through a series of layers which progressively downsample, until a bottleneck layer, after which the process is reversed.This example also illustrates why some element of randomisation is still needed in addition to the conditioning image: without it the network would always create the same output image for the same input, and we want to be able to create a variety of plausible outputs. However, experiments showed that when the randomness was provided as an input, the network just learned to ignore it. So instead noise is provided only in the form of dropout, applied at several layers during both training and test. Even then, the full available entropy is not fully exploited.In this paper, we have studied the problem of conditional image-to-image translation, in which we translate an image from a source domain to a target domain conditioned on another target-domain image as input. We have proposed a new model based on GANs and dual learning. The model can well leverage the conditional inputs to control and diversify the translation results. Experiments on two settings (symmetric translations and asymmetric translations) and three tasks (face-to-face, edges-to-shoes and edges-to-handbags translations) have demonstrated the effectiveness of the proposed model. 尝试用条件GAN网络来做image translation,让网络自己学习图片到图片的映射函数,而不需要人工定制特征。 作者从不同种类的语言翻译类比,提出了Image translation的概念,并希望在给定足够的训练数据以..

Failure of cd-GAN-rec demonstrates the necessity of “skip connections” (i.e., the connections from xsA to gA and from xsB to gB) for image reconstruction. Since the domain-specific feature level and image level reconstruction losses have implicitly put constrains on domain-specific feature to some extent, the results produced by cd-GAN-noi are closest to results of cd-GAN among the four candidate models.

As we can see, the image xA=0AB has similar style to xB, which indicates that our cd-GAN can indeed extract domain-specific features. While xB=0AB already loses conditional information of xB, it still preserves main shape of xA, which demonstrates that cd-GAN indeed extracts domain-independent features.For simplicity, we call GA→B the forward translation and GB→A the reverse translation.

The really fascinating part about pix2pix is that it is a general-purpose image-to-image translation. Instead of designing custom networks for each of the tasks above, it’s the same model handling all of them – just trained on different datasets for each task. From the abstract:

For symmetric translations, we carry out experiments on men-to-women face translations. We use the CelebA dataset [12], which consists of 84434 men’s images (denoted as domain DA) and 118165 women’s images (denoted as domain DB). We randomly choose 4732 men’s images and 6379 women’s images for testing, and use the rest for training. In this task, the domain-independent features are organs (e.g., eyes, nose, mouse) and domain-specific features refer to hair-style, beard, the usage of lipstick. For asymmetric translations, we work on edges-to-shoes and edges-to-bags translations with datasets used in [23] and [24] respectively. In these two tasks, the domain-independent features are edges and domain-specific features are colors, textures, etc. We investigate image-to-image translation using conditional-generative adversarial networks (C- GAN) on aerial-to-map images. model generates superior quality images with only 1000 training examples. 1 Introduction.

An implicit assumption of image-to-image translation is that an image contains two kinds of features111 Note that the two kinds of features are relative concepts, and domain-specific features in one task might be domain-independent features in another task, depending on what domains one focuses on in the task.: domain-independent features, which are preserved during the translation (i.e., the edges of face, eyes, nose and mouse while translating a man’ face to a woman’ face), and domain-specific features, which are changed during the translation (i.e., the color and style of the hair for face image translation). Image-to-Image translation aims at transferring images from the source domain to the target domain by preserving domain-independent features while replacing domain-specific features.

The key idea of dual learning is to improve the performance of a model by minimizing the reconstruction error. We investigate conditional adversarial networks as a general-purpose solution to image-to-image translation problems. These networks not only learn the mapping from input image to output image, but also learn a loss function to train this mapping

Convolutional Neural Nets (CNNs) have become the go-to workhorse for a variety of image tasks, but coming up with loss functions that force the CNN to do what we really want – for example, creating sharp realistic images – is an open problem generally requiring expert knowledge. Generative Adversarial Networks (GANs) get around this issue by pitting one image generating network against another adversary network, called the discriminator. It’s the job of the generative network to produce images which the discriminator network cannot distinguish from the real thing.

Both domain-specific and domain-independent feature reconstruction losses, i.e., Eqn.(10) and Eqn.(9), are removed from dual learning losses. 而且Image-to-Image Translation中很多评价是像素对像素的,所以在这里提出了分块判断的算法,在图像的每个 块上去判断是否为真,最终平均给出结果。 四、实验 If your business needs to combine one image with another, you can insert a cropped image into another photo on your Mac.

Image-To-Image Translation With Conditional Adversarial

Furthermore, cd-GAN works for both symmetric translations and asymmetric translations. In symmetric translations, both directions of translations need conditional inputs (illustrated in Figure 1(a)). In asymmetric translations, only one direction of translation needs a conditional image as input (illustrated in Figure 1(b)). That is, the translation from bag to edge does not need another edge image as input; even given an additional edge image as the conditional input, it does not change or help to control the translation result.Anyway, back to the research! The common name for the system described in today’s paper is pix2pix. You can find the code and more details online at https://github.com/phillipi/pix2pix. The name ‘pix2pix’ comes from that fact that the network is trained to map from input pictures (images) to output pictures (images), where the output is some translation of the input. Lots of image problems can be formulated this way, and the figure below shows six examples:

We carry out experiments on different tasks, including face-to-face translation, edge-to-shoe translation, and edge-to-handbag translation. The results demonstrate that our network can effectively translate image with conditional information and robust to various applications. In order to model high-frequencies, it is sufficient to restrict our attention to the structure in local image patches. Therefore, we design a discriminator architecture – which we term a PatchGAN – that only penalizes structure at the scale of patches. This discriminator tries to classify if each NxN patch in an image is real or fake. We run this discriminator convolutionally across the image, averaging all responses to provide the ultimate output of D. Translate images. You can use your phone's camera to translate text in the world around you with the Translate app. For example, you can translate signs or handwritten notes Conditionals! Learn conditional definition with examples. There are four types of conditionals in the English language: first conditional, second conditional, third conditional and zero conditional There are three main challenges in solving the conditional image translation problem. The first one is how to extract the domain-independent and domain-specific features for a given image. The second is how to merge the features from two different domains into a natural image in the target domain. The third one is that there is no parallel data for us to learn such the mappings.

Image-to-Image Translation with Conditional Adversarial Networks

In this sub section, we study other possible design choices for the model architecture in Figure 2 and losses used in training. We compare cd-GAN with other four models as follows:In Algorithm 1, the choice of optimizers Opt(⋅,⋅) is quite flexible, whose two inputs are the parameters to be optimized and the corresponding gradients. One can choose different optimizers (e.g. Adam [10], or nesterov gradient descend [18]) for different tasks, depending on common practice for specific tasks and personal preferences. Besides, the eA, eB, gA, gB, dA, dB might refer to either the models themselves, or their parameters, depending on the context. There are multiple aspects to explore for conditional image translation. First, we will apply the proposed model to more image translation tasks. Second, it is interesting to design better models for this translation problem. Third, the problem of conditional translations may be extend to other applications, such as conditional video translations and conditional text translations.

language translation, we define automatic image-to-image. translation as the problem of translating one possible rep-. resentation of a scene into another, given sufficient train image translation. Our primary contribution is to demon-. strate that on a wide variety of problems, conditional The results in this paper suggest that conditional adversarial networks are a promising approach for many image-to-image translation tasks, especially those involving high structured graphical outputs. Image-to-image translation tasks have been widely investigated with Generative Adversarial Networks (GANs) and dual learning. Therefore, changing the conditional image in the target domain will lead to diverse translation results for a fixed input image from the source domain, and therefore the.. including general image-to-image translation, text-to-image, and sketch-to-image. Section 5 discusses applications in image editing and video generation. extends GANs into a conditional model. In cGANs, the. generator G and the discriminator D are conditioned

Conditional Generative Adversarial Networks (GANs) for cross-domain image-to-image translation have made much progress recently [7, 8, 21, 12, 4, 18]. Depending on the task complexity, thousands to millions of labeled im-age pairs are needed to train a conditional GAN For men-to-women translations, from Figure 3(a), we have several observations. (1) DualGAN can indeed generate woman’s photo, but its results are purely based on the men’s photos, since it does not take the conditional images as inputs. (2) Although taking the conditional image as input, DualGAN-c fails to integrate the information (e.g., style) from the conditional input into its translation output. (3) For GAN-c, sometimes its translation result is not relevant to the original source-domain input, e.g., the 4-th row Figure 3(a). This is because in training it is required to generate a target-domain image, but its output is not required to be similar (in certain aspects) to the original input. (4) cd-GAN works best among all the models by preserving domain-independent features from the source-domain input and combining the domain-specific features from the target-domain conditional input. Here are two examples. (1) In 6-th column of 1-st row, the woman is put on red lipstick. (2) In 6-th column of 5-th row, the hair-style of the generated image is the most similar to the conditional input.In this work, we study a new setting of image-to-image translation, in which we hope to control the generated images in fine granularity with unpaired data. We call such a new problem conditional image-to-image translation.Image generation has been widely explored in recent years. Models based on variational autoencoder (VAE) [11] aim to improve the quality and efficiency of image generation by learning an inference network. GANs [6] were firstly proposed to generate images from random variables by a two-player minimax game. Researchers have been exploited the capability of GANs for various image generation tasks. [1] proposed to synthesize images at multiple resolutions with a Laplacian pyramid of adversarial generators and discriminators, and can condition on class labels for controllable generation. [19] introduced a class of deep convolutional generative networks (DCGANs) for high-quality image generation and unsupervised image classification tasks.

Accurate and Consistent Image-to-Image Conditional Adversarial

It’s time we looked at some machine learning papers again! Over the next few days I’ve selected a few papers that demonstrate the exciting capabilities being developed around images. I find it simultaneously amazing to see what can be done, and troubling to think about a ‘post-reality’ society in which audio, images, and videos can all be cheaply synthesised to tell any story, with increasing realism. Will our brains really be able to hold the required degree of skepticism? It’s true that we have a saying “Don’t believe everything you hear,” but we also say “It must be true, I’ve seen it with my own eyes…”.instead of Eqn.(7). That is, the connection from xsA to gA in the right box of Figure 2 is replaced by the connection from ^xsA to gA, and the connection from xsB to gB in the right box of Figure 2 is replaced by the connection from ^xsB to gB. A condition is what must happen before something else can happen. Examples of conditionals (note that the conditions are in italics) There are four basic conditionals in English, or in other words: there are four ways to express that something is dependent on something else While it is not difficult for existing image-to-image translation methods to convert an image from a source domain to a target domain, it is not easy for them to control or manipulate the style in fine granularity of the generated image in the target domain. Consider the gender transform problem studied in [9], which is to translate a man’s photo to a woman’s. Can we translate Hillary’s photo to a man’ photo with the hair style and color of Trump? DiscoGAN [9] can indeed output a woman’s photo given a man’s photo as input, but cannot control the hair style or color of the output image. DualGAN [22, 25] cannot implement this kind of fine-granularity control neither. Use conditional formatting in Excel to make data easier to read. Conditional formatting allows you to automatically apply formatting—such as colors, icons, and data bars—to one or more cells based on the cell value

Implementation of Efficient and Accurate Scene Text Detector (EAST) We have conducted user study to compare domain-specific features similarity between generated images and conditional images. Total 17 subjects (10 males, 7 females, age range 20−35) from different backgrounds are asked to make comparison of 32 sets of images. We show the subjects source image, conditional image, our result and results from other methods. Then each subject selects generated image most similar to conditional image. The result of user study shows that our model obviously outperforms other methods.

Image-to-Image Translation with Conditional Adversarial Nets

The image-to-image models mentioned above require paired training data between the source and target domains. There is another line of works studying unpaired domain translation. Based on adversarial training, [3] and [2] proposed algorithms to jointly learn to map latent space to data space and project the data space back to latent space. [20] presented a domain transfer network (DTN) for unsupervised cross-domain image generation employing a compound loss function including multiclass adversarial loss and f-constancy component, which could generate convincing novel images of previously unseen entities and preserve their identity. [7] developed a dual learning mechanism which can enable a neural machine translation system to automatically learn from unlabeled data through a dual learning game. Following the idea of dual learning, DualGAN [22], DiscoGAN [9] and CycleGAN [25] were proposed to tackle the unpaired image translation problem by training two cross domain transfer GANs at the same time. [15] proposed to utilize dual learning for semantic image segmentation. [14] further proposed a conditional CycleGAN for face super-resolution by adding facial attributes obtained from human annotation. However, collecting a large amount of such human annotated data can be hard and expensive. image = tf.keras.preprocessing.image.load_img(image_path) input_arr = keras.preprocessing.image.img_to_array(image) img: Input PIL Image instance. data_format: Image data format, can be either channels_first or channels_last.

In contrast, the encoders and decoders impact all the 4 losses (i.e., the GAN loss and three reconstruction errors), we use all the 4 objectives to compute gradients and update models for them. Note that since the 4 objectives are of different magnitudes, their gradients may vary a lot in terms of magnitudes. To smooth the training process, we normalize the gradients so that their magnitudes are comparable across 4 losses. We summarize the training process in Algorithm 1.

Image translation [1] is similar to language translation, which converts the input image of source domain to a corresponding image of target domain. Reference [26] proposes structural GANs, which incorporates semantic information into a conditional generative model Figure 2 shows the overall architecture of the proposed model, in which the left part is an encoder-decoder based framework for image translation and the right part includes additional components introduced to train the encoder and decoder.

Image to image translation with paired data can be considered as supervised image translation, where image x from domain X always has the target image y form domain Y. for example the well known paper: Image-to-Image Translation with Conditional Adversarial Networks, pix2pix Badges are live and will be dynamically updated with the latest ranking of this paper.

To ensure the generated xAB and xBA are in the corresponding domains, we employ two discriminators dA and dB to differentiate the real images and synthetic ones. dA (or dB) takes an image as input and outputs a probability indicating how likely the input is a natural image from domain DA (or DB). The objective function isWe use Adam [10] as the optimization algorithm with learning rate 0.0002. Batch normalization is applied to all convolution layers and deconvolution layers except for the first and last ones. Minibatch size is fixed as 200 for all the tasks.

GAN-c. To verify the effectiveness of dual learning, we remove the dual learning losses of cd-GAN during training and obtain GAN-c.The goal of the encoders and decoders eA, eB, gA, gB is to generate images as similar to natural images and fool the discriminators dA and dB, i.e., they try to minimize ℓGAN. The goal of dA and dB is to differentiate generated images from natural images, i.e., they try to maximize ℓGAN. OCR - Extract Text From Image Image Converter Split Merge PDF Royalty Free Cliparts Web Page To Image Web Page To PDF Read Arabic Newspapers Watch Arabic Channels Write Arabic Using English To give the generator a means to circumvent the bottleneck for information like this, we add skip connections, following the general shape of a “U-Net”. Our proposed framework can learn to separate the domain-independent features and domain-specific features. In Figure 2, consider the path of xA→eA→xiA→gB→xAB. Note that after training we ensure that xAB is an image in domain DB and the features xiA are still preserved in xAB. Thus, xiA should try to inherent the features that are independent to domain DA. Given that xiA is domain independent, it is xsB that carries information about domain DB. Thus, xsB is domain-specific features. Similarly, we can see that xsA is domain-specific and xiB is domain-independent.
