Complex network theory are introduced to image recognition field recently. But the cost in storage space and time are obvious that the efficiency of the method is reduced. Consider the methods based on image contour can achieve high identify efficiency with simple process, a Face Recognition Method Based on Complex Network and Image Contours is discussed in this paper. A set of shape contour and color contours are taken into account. The main idea of the approach is to extract the face shape contour and color contours, model them into graphs and use complex network methodology to extract a feature vector for face recognition. Experiments show that the proposed method could effectively control the scale of the complex network and adapt to the changes in the boundary shape with efficient power of face recognition. The proposed method is also proved to be scale invariant and rotation invariant.
