Improve Temporal Reasoning in Multimodal Large Language Models via Video Contrastive Decoding

NeurIPS 2025poster

A major distinction between video and image understanding is that the former requires reasoning over time. Existing Video Large Language Models (VLLMs) demonstrate promising performance in general video understanding, such as brief captioning or object recognition within individual frames. However,…

Unified Dense Prediction of Video Diffusion

CVPR 2025poster

We present a unified network for simultaneously generating videos and their corresponding entity segmentation and depth maps from text prompts. We utilize colormap to represent entity masks and depth maps, tightly integrating dense prediction with RGB video generation. Introducing dense prediction i…

UniGS: Unified Representation for Image Generation and Segmentation

CVPR 2024poster

This paper introduces a novel unified representation of diffusion models for image generation and segmentation. Specifically we use a colormap to represent entity-level masks addressing the challenge of varying entity numbers while aligning the representation closely with the image RGB domain. Two n…
