Face Recognition by Expression-Driven Sketch Graph Matching
We present a novel face recognition method using automatically extracted sketch by a multi-layer grammatical face model. First, the observed face is parsed into a 3layer (face, parts and sketch) graph. In the sketch layer, the nodes not only capture the local features (strength, orientation and profile of the edge), but also remember the global information inherited from the upper layers (i.e. the facial part they belong to and status of the part). Next, a sketch graph matching is performed between the parsed graph and a pre-built reference graph database, in which each individual has a parsed sketch graph. Similar to the other successful edge-based methods in the literature, the use of sketch increases the robustness of recognition under varying lighting conditions. Furthermore, with high-level semantic understanding of the face, we are able to perform an intelligent recognition process driven by the status of the face, i.e. changes in expressions and poses. As shown in the experimen...
