CoVisco: Codec-Native Vision Encoder with Native Token Compression for Unified Image-Video Understanding
Vision-language models face a fundamental scaling bottleneck: the number of visual tokens grows with both temporal duration and spatial resolution, making long-video understanding expensive for the vision encoder and the language model. Existing methods often compress visual tokens after dense encoding, creating a mism...
