Accuracy of the human face contour can help evaluate the facial orientation to retrieve facial features to identifying or verifying a human facial expression. Automatic extraction human face contour algorithm with high accuracy is necessary. In this paper, a novel flowchart of the face contour extraction algorithm was proposed for improving accuracy of face contours. Poisson Gradient Vector Flow (PGVF)...
This paper proposed a method of quaternion K-L transform and biomimetic pattern recognition (BPR) for color face recognition. The BPR aimed at optimal covering in the feature space Rn using some complex geometric bodies for cover samples distribution in Rn approximately in order to ??recognize??. We used quaternion K-L transform to extract the Eigen-faces of training samples and algebraic feature...
Studies on learning problems from geometry perspective have attracted an ever increasing attention in machine learning, leaded by Biomimetic Pattern Recognition on information geometry. Biomimetic Pattern Recognition is a new model of Pattern Recognition based on “matter cognition” instead of “matter classification”. This new model is much closer to the function of human being, than traditional statistical...
Face recognition using cubic B-spline wavelet transform is proposed in this paper. The proposed scheme is based on the analysis of face recognition using wavelet transform and the viewpoint that detail subbands after wavelet transform also have a lot of feature information. Then, the feasibility of a new application that cubic B-spline wavelet use Mallat algorithm to decompose an image under some...
