ScriptHOI: Learning Scripted State Transitions for Open-Vocabulary Human-Object Interaction Detection

Bao Ngoc Le, Linh Chi Vo, Minh Anh Nguyen, Quang Huy Tran, Suiyang Guang, Tuan Kiet Pham

Decomposing interaction phrases into state slots verifies multiple visual cues and improves rare and unseen human-object interaction detection.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Experiments on HICO-DET, V-COCO, and open-vocabulary HOI splits show that ScriptHOI improves rare and unseen interaction recognition while substantially reducing affordance-conflict false positives.

C2weakest assumption

That the visual state tokenizer can reliably parse human-object pairs into accurate state tokens for the six slots and that script coverage and conflict estimates provide valid calibration without introducing new biases or missing critical visual cues.

C3one line summary

ScriptHOI improves rare and unseen HOI recognition by decomposing phrases into state slots, using visual tokenization and slot-wise matching for script coverage and conflict to calibrate predictions and constrain training on incomplete labels.
