ToonCrafter is an AI-powered animation tool that transforms static cartoon images into smooth, lively animations. It automatically generates transition frames between keyframes using AI algorithms, maintaining consistency with the original artistic style while providing pixel-level detail extraction and seamless transition animations. ToonCrafter was co-developed by researchers from the Chinese University of Hong Kong, City University of Hong Kong, and Tencent AI Lab, utilizing core technologies like cartoon correction learning, dual-reference 3D VAE decoders, and sparse sketch guidance.
