HiMu framework enhances long video question answering with hierarchical frame selection

Researchers have developed HiMu, a novel framework designed to improve frame selection for long-form video question answering tasks. This training-free system decomposes complex queries into a hierarchical logic tree, utilizing specialized experts for vision and audio processing. HiMu's approach normalizes and composes expert signals using fuzzy logic to maintain temporal sequencing and modality bindings, outperforming prior methods on benchmarks like Video-MME and LongVideoBench.
