TripleSumm: Adaptive Triple-Modality Fusion for Video Summarization
This addresses the need for efficient video summarization to handle exponential video growth, with a novel method for a known bottleneck in multimodal fusion.
The authors tackled the problem of video summarization by proposing TripleSumm, an architecture that adaptively fuses visual, text, and audio modalities at the frame level, achieving state-of-the-art performance and outperforming existing methods by a significant margin on four benchmarks.
The exponential growth of video content necessitates effective video summarization to efficiently extract key information from long videos. However, current approaches struggle to fully comprehend complex videos, primarily because they employ static or modality-agnostic fusion strategies. These methods fail to account for the dynamic, frame-dependent variations in modality saliency inherent in video data. To overcome these limitations, we propose TripleSumm, a novel architecture that adaptively weights and fuses the contributions of visual, text, and audio modalities at the frame level. Furthermore, a significant bottleneck for research into multimodal video summarization has been the lack of comprehensive benchmarks. Addressing this bottleneck, we introduce MoSu (Most Replayed Multimodal Video Summarization), the first large-scale benchmark that provides all three modalities. Extensive experiments demonstrate that TripleSumm achieves state-of-the-art performance, outperforming existing methods by a significant margin on four benchmarks, including MoSu.
