This thesis proposes a new feature vector for static gesture recognition and the application of a neural fuzzy network as a recognizer. For gesture recognition, the paper considers both the gestures of the two human hands. For each hand, four kinds of main gestures, including arm up and bending, in straight, down are considered. In total, the number of gestures is sixteen. For feature extraction, the thesis first uses a moving object segmentation algorithm to segment human body from the extracted background. A sequence of image processing is used to obtain a complete silhouette. Histograms of horizontal and vertical projections of the silhouette are then used to clip two focused body regions for the two hands. Each focus region is equally divided into fifteen non-overlapping grids. The percentage of human body silhouette pixels in each grid is found, generating a total of sixteen features for a hand. Each of the two fifteen dimensional feature vectors is fed as inputs to a neural fuzzy network for recognition. Experimental results show that the proposed method recognizes the sixteen gestures with high accuracy. Comparisons with an eigenvector-based feature extraction method and a template-matching recognition method demonstrate the advantage of the proposed recognition method.
