A hand gesture recognition method is presented for human-computer interaction,which is based on fingertip localization. First,hand gesture is segmented from the background based on skin color characteristics. Second,feature vectors are selected with equal intervals on the boundary of the gesture,and then gestures' length normalization is accomplished. Third,the fingertip positions are determined by the feature vectors' parameters,and angles of feature vectors are normalized. Finally the gestures are classified by support vector machine. The experimental results demonstrate that the proposed method can recognize 9 gestures with an accuracy of 94.1%.
