Method for recognizing gesture and electronic device
First Claim
1. A gesture recognition method for an electronic device to recognize a gesture of at least a hand, the gesture recognition method comprising:
- capturing a hand image of the hand, wherein the hand image includes a hand region;
calculating a geometric center of the hand region;
deploying at least a concentric circle on the hand image with the geometric center as a center of the concentric circles;
counting the number of a plurality of intersection points of the edge of the hand region on each of the concentric circles respectively to determine a feature vector of the gesture; and
according to the feature vector, performing a hand recognition to recognize the gesture of the hand.

Abstract
A method for recognizing a gesture adopted by an electronic device to recognize a gesture of at least a hand. In the method, a hand image of the hand is captured and the hand image includes a hand region. A geometric center of the hand region is calculated. At least a concentric circle is disposed on the hand region with the geometric center as the center of the concentric circles. A number of intersection points of each concentric circle and the hand region is calculated respectively to determine a feature vector of the gesture. According to the feature vector, a hand recognition is performed to recognize the gesture of the hand.
