This paper proposes a lightweight network structure that can implement unpaired training sets to complete one-way image mapping, based on the generative adversarial network (GAN) and a fixed-parameter edge detection convolution kernel. Conditional adversarial networks as a general-purpose solution to image-to-image translation. 2016. 2. Generator Network: tries to produce realistic-looking samples. The listed color normalization approaches are based on a style transfer method in which the style of the input image is modified based on the style image, when preserving the content of the input image. Cycle-consistency loss is a widely used constraint for such problems. "Image-to-Image Translation with Conditional Adversarial Networks", in CVPR 2017. To solve this issue, previous works [47, 22] mainly focused on encouraging the correlation between the latent codes and their generated images, while ignoring the relations between images . #PAPER Image-to-Image Translation with Conditional Adversarial Networks, pix2pix (Isola 2016) ^pix2pix. This makes it possible to apply the same generic approach to problems that traditionally While existing UI2I methods usually require numerous unpaired images from different domains for training, there are many scenarios where training data is quite limited. Image conversion has attracted mounting attention due to its practical applications.

Image-to-image translation tasks have been widely investigated with Generative Adversarial Networks (GANs). By contrast, unsupervised image-to-image translation methods , , aim to learn a conditional image synthesis function to map an source domain image to a target domain image without a paired dataset. 1. CycleGAN was originally proposed as an image-to-image translation model, an extension of GAN, using a bidirectional loop of GANs to realize image style-conversion [25]. These networks not only learn the mapping from input image to output image, but also learn a loss function to train this mapping. Image-to-image translation is the task of changing a particular aspect of a given image to another. Abstract. . Kim et al. Conditional Generative Adversarial Networks (cGANs) have enabled controllable image synthesis for many computer vision and graphics applications. 13092: Numerous task-specific variants of conditional generative adversarial networks have been developed for image completion. However, existing approaches are mostly designed in an unsupervised manner, while little attention has been paid to domain information within unpaired data. Image to Image translation have been around for sometime before the invention of CycleGANs. Generative Adversarial Networks".

The algorithm also learns an inverse mapping function F : Y 7 X using a cycle consistency loss such that F (G(X)) is indistinguishable from X. Conditional generative adversarial networks (cGANs) target at synthesizing diverse images given the input conditions and latent codes, but unfortunately, they usually suffer from the issue of mode collapse. The conditional generative adversarial network, or cGAN for short, is an extension to the GAN architecture that makes use of information in addition to the image as input both to the generator and the discriminator models. ISBN 9780128235195, 9780128236130 . . GANs can generate images that reach high-level goals, but the general-purpose use of cGANS were unexplored. .

Every individual in NxN output maps to a patch in the input image. This motivated researchers to propose a new GAN-based network that offers unpaired image-to-image translation. However, for many tasks, paired train- ing data will not be available. Facial unpaired image-to-image translation is the task of learning to translate an imagefrom a domain (e.g. However, due to the strict pixel-level constraint, it cannot perform geometric changes, remove large objects, or ignore irrelevant texture. This study aimed to assess the clinical feasibility of employing synthetic diffusion-weighted (DW) images with different b values (50, 400, 800 s/mm2) for the prostate cancer patients with the help of three models, namely CycleGAN, Pix2PiX, and DC2Anet. Unpaired image-to-image translation was aimed to convert the image from one domain (input domain A) to another domain (target domain B), without providing paired examples for the training.
