Human object interaction detection using two-direction spatial enhancement and exclusive object prior
作者：
Highlights：
• One of the significant problems in HOI detection is mis-grouping, which is no interaction human-object pair can be easily mis-grouped and misclassified as an action.
• To suppress the no interaction human-object pairs, we propose a spatial enhancement approach to enforce fine-level spatial constraints in two directions between human body parts and object parts.
• At inference, we propose a human-object regrouping approach for object- exclusive actions by considering the object-exclusive property of the interactive object, where the target object should not be shared by more than one human.
