Synthesis, Style Editing, and Animation of 3D Cartoon Face

As a popular kind of stylized face, cartoon faces have rich application scenarios. It is challenging to create personalized 3D cartoon faces directly from 2D real photos. Besides, in order to adapt to more application scenarios, automatic style editing, and animation of cartoon faces is also a crucial problem that is urgently needed to be solved in the industry, but has not yet had a perfect solution. To solve this problem, we first propose “3D face cartoonizer”, which can generate high-quality 3D cartoon faces with texture when fed into 2D facial images. We contribute the first 3D cartoon face hybrid dataset and a new training strategy which first pretrains our network with low-quality triplets in a reconstruction-then-generation manner, and then finetunes it with high-quality triplets in an adversarial manner to fully leverage the hybrid dataset. Besides, we implement style editing for 3D cartoon faces based on k-means, which can be easily achieved without retrain the neural network. In addition, we propose a new cartoon faces' blendshape generation method, and based on this, realize the expression animation of 3D cartoon faces, enabling more practical applications. Our dataset and code will be released for future research.
