The invention discloses a three-dimensional face recognition method and a data processing device using the same. The invention firstly combines two complementary uncertainty measures in the neighborhood system to define a more comprehensive feature integration uncertainty measure, which is used to measure the importance of features; then a feature reduction algorithm based on neighborhood combination measure is proposed, which is used to select features closely related to face recognition and obtain the optimal feature combination; finally, the selected features As the input vector of the support vector machine classifier, the recognition result of the three-dimensional face is obtained. The experimental results show that the 3D face recognition method based on rough sets and SVM can greatly reduce the recognition time while ensuring the recognition accuracy, has certain robustness to changing facial expressions, and has stronger generalization performance.
Description
technical field [0001] The invention relates to the fields of digital image processing and pattern recognition, in particular to a three-dimensional face recognition method and a data processing device using the method. Background technique [0002] As a biometric feature, the human face has the advantages of not being lost, not easy to be copied, convenient to collect, unique, and undetectable. It is attracting more and more attention and has entered various fields of social life. Compared with other human body biometric identification systems such as retina, fingerprint, iris, voice, and palm print, the face recognition system has a very wide application prospect because of its convenience and friendliness, especially in the face recognition access control attendance system, human The application of facial recognition ATM intelligent video alarm system, face recognition public security intelligent alarm system for chasing criminals, video conferencing, and medical applicat...
