IMAGE BASED MOTION GESTURE RECOGNITION METHOD AND SYSTEM THEREOF
First Claim
1. An image based motion gesture recognition method, comprising steps of:
- receiving image frames;
performing a hand posture detection according to said image frames, to obtain a first hand posture;
determining whether said first hand posture matches a predefined starting posture;
if said first hand posture matches said predefined starting posture, performing a movement tracking according to hand locations on said image frames, to obtain a motion gesture;
performing said hand posture detection according to said image frames during said movement tracking, to obtain a second hand posture;
determining whether said second hand posture matches a predefined ending posture; and
if said second hand posture matches said predefined ending posture, stopping said movement tracking.

Abstract
An image based motion gesture recognition method and system thereof are disclosed. In embodiment, a hand posture detection is performed according to the received image frames, to obtain a first hand posture. It is then determined whether the first hand posture matches a predefined starting posture or not. If the first hand posture matches said predefined starting posture, movement tracking is performed according to hand locations on image frames, to obtain a motion gesture. During said movement tracking, the hand posture detection is performed according to said image frames to obtain a second hand posture, and it is determined whether the second hand posture matches a predefined ending posture. If the second hand posture matches the predefined ending posture, the movement tracking is stopped. Therefore, reduce complexity motion gesture recognition can be reduced and the reliability in interaction can be improved.
