Скачать или смотреть ToonComposer: AI-Assisted Cartoon Production and Post-Keyframing

This academic paper introduces *ToonComposer**, a novel generative AI model designed to **streamline cartoon and anime production* by unifying the typically separate and labor-intensive stages of inbetweening and colorization into a single "post-keyframing" process. The model leverages a *Diffusion Transformer (DiT)* architecture, adapted for cartoon aesthetics using a *Spatial Low-Rank Adapter (SLRA)* to maintain temporal coherence. ToonComposer features a *sparse sketch injection mechanism* for precise artist control, even with minimal inputs, and *region-wise control* to automatically generate content in unsketched areas. Extensive evaluations on both synthetic and human-drawn benchmarks, including a new *PKBench* dataset, demonstrate ToonComposer's superior visual quality, motion consistency, and production efficiency compared to existing methods. The paper highlights its potential to significantly *reduce manual workload* and enhance flexibility in animation workflows.
