AniDoc is an automated line art coloring model aimed at streamlining animation production workflows and reducing labor costs. The model leverages the prior knowledge of video diffusion models, employing explicit correspondence mechanisms and injection modules to align color information from reference images to the input sketches, enhancing color accuracy. It uses a two-stage training strategy to minimize the need for interpolating intermediate frames. With binary sketches and data enhancement techniques, it improves training stability and coloration effects. AniDoc demonstrates exceptional performance in both quantitative and qualitative results, offering an effective solution for automatically coloring video line art and boosting animation production efficiency.
