face recognition manufacturer < / a > discussion on face recognition method of elastic graph matching

The elastic graph matching method defines a distance that is invariant to the usual face deformation in two-dimensional space, and uses the attribute topology to represent the face. Any vertex of the topology contains a feature vector to record the information of the face near the vertex

The elastic map matching method combines the gray characteristics and geometric factors. It can allow the image to have elastic deformation during comparison. It has achieved good results in overcoming the influence of expression change on recognition. At the same time, it does not need multiple samples for training for a single person
