Bridging the Pose-Semantic Gap: A Cascade Framework for Text-Based Person Anomaly Search

Chuxin Wang, Guijin Luo, Sihang Cai, Tao Jin, Yixuan Tang, Zequn Xie, Zhou Zhao

A two-stage cascade filters candidates by skeletal pose then verifies semantics with a multi-agent squad to bridge the gap where different actions share similar structures.

Claims

C1strongest claim

We propose the Structure-Semantic Decoupled Cascade (SSDC) framework, which decouples retrieval into two stages: (1) Structure-Aware Coarse Retrieval... and (2) Detective Squad Interaction... Experiments on the PAB benchmark show that SSDC achieves state-of-the-art performance by balancing efficiency and semantic reasoning.

C2weakest assumption

That skeletal geometry provides a sufficiently reliable coarse filter for semantically distinct actions and that the multi-agent LLM verification stage can resolve remaining ambiguities accurately without introducing new errors or prohibitive latency.

C3one line summary

SSDC is a two-stage cascade that first filters by skeletal similarity then applies a multi-agent LLM squad for semantic verification, achieving SOTA on the PAB benchmark for text-based person anomaly search.
