Abstract

The invention provides a millimeter wave image-based face recognition method and system. The method comprises the steps of performing size processing on a millimeter wave image to obtain a processed image consistent with a registered image in a face image retrieval library in size; extracting face features of the processed image to establish feature extraction mapping; and comparing the feature extraction map with a pre-established preliminary feature map of the registered image to obtain a matched preliminary feature map. According to the invention, face recognition can be realized based on the millimeter wave image generated by the millimeter wave security check imaging system.

Description

technical field [0001] The present invention relates to the technical field of face recognition, in particular to a face recognition method based on millimeter wave images and a face recognition system based on millimeter wave images. Background technique [0002] For the increasing security inspection pressure, in addition to the need for security inspection equipment that can identify dangerous goods carried by the human body (such as knives, guns, explosives, etc.), security inspection equipment that can quickly identify people's identity information is also an important demand. At present, the millimeter-wave security imaging technology is becoming more and more mature, and has been widely used in the inspection of dangerous goods carried by the human body. However, various biometric identification technologies based on passenger identities cannot be realized technically based on the millimeter-wave security imaging system. Contents of the invention [0003] The techni...
