A new distance metric learning algorithm for hand posture recognition is proposed in this paper. By adopting the Fourier descriptor of the hand shape as the sample feature, the algorithm exerts new constrains on the distance of inter-class pairs, and learns a Mahalanobis distance metric matrix by minimizing the distance of intra-class pairs and maximizing the distance of inter-class pairs simultaneously. Then k-nearest neighbor classifier is used to test the introduced method. The experimental results on multi-class hand posture recognition by k-nearest neighbor classifier show that the presented algorithm has less error rate than other distance metric learning algorithms.
