HAND RECOGNIZING METHOD, SYSTEM, AND STORAGE MEDIUM
First Claim
1. A hand recognizing method, at a hand recognizing system, comprising:
- acquiring a binary image into which an image is segmented based upon the skin color of a human body;
extracting a connectivity domain in the binary image as a connectivity domain to be recognized;
calculating a feature vector of a corresponding sample of the connectivity domain to be recognized;
calculating the distances between the feature vector of the connectivity domain to be recognized, and feature vectors of hand sample connectivity domain, and the distances between the feature vector of the connectivity domain to be recognized, and feature vectors of non-hand sample connectivity domains; and
obtaining K samples with the shortest distances, determining whether the number of hand samples among the K samples is more than the number of non-hand samples, and if so, then determining that the connectivity domain to be recognized is a hand feature, wherein K represents a positive odd number.
