## Description

Latent Diffusion is a framework for high-resolution image synthesis that performs the denoising process within a compressed latent space. It uses variational autoencoders to encode images into a lower-dimensional representation, reducing the computational cost of noise prediction compared to operating on raw pixels.

The project enables text-to-image generation by integrating natural language descriptions through cross-attention conditioning. It also supports image inpainting and restoration, filling masked or missing image areas with generated content, and example-based synthesis using retrieved visual samples.

The system includes capabilities for training both the regularized autoencoder models used for compression and the latent diffusion models used for synthesis. It supports various sampling methods, including unconditional image generation and classifier-free guidance to balance sample fidelity and diversity.
