InsightTok

InsightTok is a discrete visual tokenizer designed to improve the fidelity of text and faces, two of the most challenging yet perceptually important structures in autoregressive image generation.

It was introduced in the paper InsightTok: Improving Text and Face Fidelity in Discrete Tokenization for Autoregressive Image Generation.
