Cycle GANs 不需要对齐语料,但是需要两个domain的数据。 有两个生成器,从一个domain到另一个domain的搜索 。 有两个判别器。 loss函数有两项,一项是adversarial loss,一个是一致性损失。 adversarial loss要求生成的图像更加的逼真,consistence loss要求翻译回来的句子和原始的句子一样。 cycle gan中的生成器,接受的...
Adversarial lossMost of the papers related to conditional GANs, use vanilla GAN objective as the loss[20][25] function. Recently [47] provides an alternative way of using least aquare GAN [23] which is more stable and generates higher quality results. We use WGAN-GP [11] as the critic ...

论文题目:High-Resolution Image Synthesis and Semantic Manipulation with Conditional GANs 论文链接:CVPR 2018 Open Access Repository (thecvf.com) 引言 本文主要提出了一种从semantic label map生成高分辨率图像的方法,具有广泛的应用场景:训练数据合成、图像编辑(先通过segmentation生成label map,在label domain编辑obj...
The multiplicative interaction of the input data can promote the domain adversarial model to align multiple domains at the feature and class level, and form a feature space shared by the multiple domains. Besides, the domain discriminator uses the entropy criterion to adjust the priority of samples...

Motion artefacts caused by the patient’s body movements affect magnetic resonance imaging (MRI) accuracy. This study aimed to compare and evaluate the accuracy of motion artefacts correction using a conditional generative adversarial network (CGAN) with
is more stable than the adversarial network of GANs. Although the diffusion model has great advantages in image generation, its sampling speed is slow during training and inference, resulting in very high training costs. Therefore, considering factors such as training cost and image generation quality...

Image imputation refers to the task of generating a type of medical image given images of another type. This task becomes challenging when the difference between the available images, and the image to be imputed is large. In this manuscript, one such app
