HUMAN BODY GENDER AUTOMATIC RECOGNITION METHOD AND APPARATUS

摘要

A human body gender automatic recognition method includes: acquiring a current millimeter wave grayscale image, and determining gender part region positions of a human body in the millimeter wave grayscale image according to a pre-set body proportion; extracting a region sub-image corresponding to the gender part region position; performing dimension normalization on the region sub-image to obtain the region sub-image after normalization; performing feature information extraction on the region sub-image after normalization to obtain feature information about the region sub-image after normalization; recognizing the millimeter wave grayscale image by means of each pre-set classifier, and respectively outputting results; and integrating the output results to obtain a classification recognition result of the millimeter wave grayscale image. The method has relatively high recognition rate and calculation efficiency, and solves the problem of a privacy protection and detection method in a millimeter wave security inspection system.
