POINTS-Long: Adaptive Dual-Mode Visual Reasoning in MLLMs

CVPR 2026

Multimodal Large Language Models (MLLMs) have recently demonstrated remarkable capabilities in cross-modal understanding and generation. However, the rapid growth of visual token sequences--especially in long-video and streaming scenarios--poses a major challenge to their scalability and real-world

LamRA: Large Multimodal Model as Your Advanced Retrieval Assistant

CVPR 2025poster

With the rapid advancement of multimodal information retrieval, increasingly complex retrieval tasks have emerged. Existing methods predominately rely on task-specific fine-tuning of vision-language models, often those trained with image-text contrastive learning. In this paper, we explore the possi…

Learning Streaming Video Representation via Multitask Training

ICCV 2025poster

Understanding continuous video streams plays a fundamental role in real-time applications, including embodied AI and autonomous driving. Unlike offline video processing, streaming video understanding requires the ability to process video streams frame by frame, preserve historical information, and m…

Audio-Visual Segmentation via Unlabeled Frame Exploitation

CVPR 2024poster

Audio-visual segmentation (AVS) aims to segment the sounding objects in video frames. Although great progress has been witnessed we experimentally reveal that current methods reach marginal performance gain within the use of the unlabeled frames leading to the underutilization issue. To fully explor…

Local-Global Transformer Enhanced Unfolding Network for Pan-sharpening

IJCAI 2023poster

Pan-sharpening aims to increase the spatial resolution of the low-resolution multispectral (LrMS) image with the guidance of the corresponding panchromatic (PAN) image. Although deep learning (DL)-based pan-sharpening methods have achieved promising performance, most of them have a two-fold deficien…
