FACE GENDER RECOGNITION METHOD, FACE GENDER CLASSIFIER TRAINING METHOD AND DEVICE

摘要

A face gender recognition method, and a face gender classifier training method and device, wherein the face gender recognition method comprises: performing face detection on an image to be recognized, and acquiring a target face in the image to be recognized (11); performing face feature point extraction on the target face (12); obtaining a face region of interest image according to the face feature point (13); performing feature extraction on the face region of interest image to obtain a feature image (14); performing grayscale compression processing on the feature image, and obtaining a grayscale histogram of the grayscale compressed image (15); obtaining a gender feature of the target face according to the grayscale histogram (16); and inputting the gender feature of the target human face into the trained face gender classifier to obtain a gender recognition result of the target face (17).
