VideoPerceiver: Enhancing Fine-Grained Temporal Perception in Video Multimodal Large Language Models

arXiv — cs.CVTuesday, November 25, 2025 at 5:00:00 AM
  • VideoPerceiver has been introduced as a novel video multimodal large language model (VMLLM) designed to enhance fine-grained temporal perception in video understanding. This model addresses the limitations of existing VMLLMs, particularly their inability to effectively reason about brief actions in short clips or rare transient events in longer videos, through a two-stage training framework involving supervised fine-tuning and reinforcement learning.
  • The development of VideoPerceiver is significant as it represents a step forward in improving the sensitivity of models to fine-grained motion cues, which is crucial for applications in video analysis and understanding. By enhancing the model's ability to generate accurate descriptions from both complete and modified video inputs, it aims to outperform previous models in video comprehension tasks.
  • This advancement is part of a broader trend in artificial intelligence where researchers are increasingly focusing on improving the efficiency and effectiveness of multimodal models. The integration of various techniques, such as reinforcement learning and contrastive loss, reflects ongoing efforts to tackle challenges in video processing, including the need for better temporal grounding and the management of computational costs associated with long video sequences.
