SemHiTok: A Unified Image Tokenizer via Semantic-Guided Hierarchical Codebook for Multimodal Understanding and Generation

SemHiTok is a new image tokenizer that uses a semantic-guided hierarchical codebook to balance high-level semantic understanding and low-level pixel feature retention for multimodal tasks. This innovation allows content creators to achieve superior performance in both image reconstruction and multimodal generation, enhancing the capabilities of unified models like LLaVA-v1.5.
