Local and Global GAN

Local Class-Specific and Global Image-Level Generative Adversarial Networks for Semantic-Guided Scene Generation
Hao Tang, Dan Xu, Yan Yan, Philip H.S. Torr, Nicu Sebe. <br>In CVPR 2020.<br> The repository offers the official implementation of our paper in PyTorch.

In the meantime, check out our related ACM MM 2020 paper Dual Attention GANs for Semantic Image Synthesis, and TIP 2021 paper Layout-to-Image Translation with Double Pooling Generative Adversarial Networks.
