## Description

pix2pix is a framework for image-to-image translation using conditional generative adversarial networks. It functions as a supervised trainer and visual domain mapper designed to learn a mapping between input and output images for style and domain transfer.

The system utilizes a U-Net encoder-decoder architecture combined with a PatchGAN local discriminator to enforce high-frequency local consistency. It employs L1 loss regularization to ensure generated outputs remain structurally close to the ground truth.

The project covers a broad range of computer vision capabilities, including semantic image generation from label maps or edge sketches and visual style translation. It includes data preparation utilities for image augmentation and the creation of paired training datasets, as well as tools for real-time training visualization of loss plots and generated samples.

Model evaluation is supported through semantic segmentation testing and ground-truth accuracy comparisons, while state persistence is managed via regular model checkpoint saving.
