In this paper a new algorithm to locate the Elastic Labeled Graph is proposed for the face recognition approach based on Gabor wavelet jets. We extend Direct Appearance Model (DAM) to a hierarchical organization, which performs faster and more remote compared with the traditional graph localization method used in Elastic Bunch Graph Matching. A tracking recognition scheme is further discussed through employing the hierarchical DAM in a video sequence. Experimental results demonstrate the effectiveness of the method in locating and tracking the elastic graph.
