The authors present a diffusion method for colorizing animation sketches from image references while limiting interference from reference composition. It uses the sketch to guide drawing and separately processes masked foreground and background reference features with LoRA branches and a recovery transformer. On comparisons, it improves FID, MS-SSIM, and CLIP similarity over baselines, but not PSNR; results depend on mask quality.
