Feature Point Matching for Human-Computer Interaction Multi-Feature Gesture Recognition Based on Virtual Reality VR Technology

This paper proposes a system for human-computer interaction using video gesture extraction. The system includes four modules: video acquisition and separation, image preprocessing, gesture extraction and recognition, and virtual reality human-computer interaction. This paper proposes a system for human-computer interaction using video gesture extraction. The system includes four modules: video acquisition and separation, image preprocessing, gesture extraction and recognition, and virtual reality human-computer interaction. Among them, the contour feature should be listed by the LCS description method. This article also uses three methods to describe the characteristics of dynamic gestures, which are static gesture sequence, fingertip movement feature, and palm movement feature. The static gesture sequence refers to a set of ordered static gesture numbers.
