Pix2pixHD

pix2pixHD is a conditional generative adversarial network designed to transform semantic label maps into high-resolution photorealistic images. It functions as a high-resolution image synthesizer and an image-to-image translation model capable of producing synthetic images at 2048x1024 resolution.

The system includes a semantic image editor that allows for the modification of high-resolution visuals by updating the underlying semantic label maps. This enables interactive image editing and the generation of photorealistic images based on source images or discrete label maps.

The framework provides tools for image translation model training using custom datasets. It incorporates training acceleration through automatic mixed precision and multi-GPU data parallelism to manage high-resolution tensors.
