Image Inpainting And Region Editing

via “image inpainting with masked region filling”

Implementation of Imagen, Google's Text-to-Image Neural Network, in Pytorch

Unique: Incorporates masks directly into diffusion process through concatenation with noisy images, enabling spatial awareness without separate mask encoder, and supports both training and inference with arbitrary mask patterns

vs others: Integrates masking into core diffusion loop rather than post-processing, enabling better boundary handling and semantic understanding of masked regions compared to naive blending approaches
