Video-based palm print and palm vein joint registration and recognition method

Abstract

The present invention provides a video-based palm print and palm vein joint registration and recognition method. The method includes a registration method and a recognition method. According to the registration method, images are extracted from a registration palm vein video and a registration palm print video; registration palm vein template features, registration palm vein LBP features and registration palm print local invariant features are obtained; and the registration palm vein template features, registration palm vein LBP features and registration palm print local invariant features are stored in a registration database. According to the recognition method, images are extracted from a recognition palm vein video and a recognition palm print video; recognition palm vein template features, recognition palm vein LBP features and recognition palm print local invariant features are obtained; and the recognition palm vein template features, the recognition palm vein LBP features and the recognition palm print local invariant features are matched, so that whether a user has been registered is recognized. With the joint registration and recognition method of the invention adopted, the palm recognition of a motion video can be realized, the user friendliness of the recognition can be effectively enhanced; a new strategy according to which a palm rotation video and a palm cross sweep video are registered in a fused manner is provided, and therefore, the richness and completeness of registration features can be improved, the robustness of the method to different recognition attitudes is improved; and a cascade fusion strategy is provided, and therefore, the recognition speed of registered users can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of image processing and analysis, and more specifically, relates to a method for joint registration and identification of palm prints and veins based on video. Background technique [0002] Today, with the rapid development of network information technology, identification technology based on biometrics has begun to receive widespread attention and applications, among which biometrics based on hands are more concerned by researchers because of the richness of information contained and the convenience of collection. , including fingerprint recognition, finger vein recognition, finger stripe recognition, finger shape recognition, palm print recognition, palm vein recognition and hand vein recognition, etc. The study found that the use of multi-modal or multiple biometric fusion technologies can obtain better recognition performance and reliability than a single biometric technology, and can increase the diffic...

AI Technical Summary

Problems solved by technology

However, the current method of combining video recognition with palmprint and palm vein recognition is still blank, so it is necessary to design a video-based palmprint and palm vein joint registration and recognition method to make the biometric system more stable and effective.
