Gender identification method and apparatus based on face image

Abstract

The invention discloses a gender identification method and apparatus based on a face image. The method comprises the steps of: carrying out discrimination of gender classification on a face image to be identified by a preset prior model in a deep convolution neural network, obtaining a gender discrimination result, and if a probability value of the gender discrimination result is greater than a preset probability value, determining that a gender discriminated in the gender discrimination result is a gender of a person described in the face image to be identified; and if the probability value of the gender discrimination result is smaller than the preset probability value, by comparison of a cosine similarity between features of the face image to be identified and features of a face image sample, identifying the gender of the person described in the face image, wherein the face image sample is an image sample of an entire face. Therefore, in the complex imaging case, the deep convolution neural network is combined with feature comparison of the images, and auxiliary identification can be carried out by utilizing depth texture, edge and color features of the face, so that accuracy of gender identification is improved.

Description

technical field [0001] The invention belongs to the technical field of image recognition, and in particular relates to a gender recognition method and device based on a human face image. Background technique [0002] Face recognition is a biometric technology for identification based on human facial feature information. Use a video camera or camera to collect images or video streams containing human faces, and automatically detect and track human faces in the images, usually also called portrait recognition and facial recognition. Face recognition products have been widely used in finance, justice, military, public security, border inspection, government, aerospace, electric power, factories, education, medical care and many enterprises and institutions. For example, face recognition access control time attendance system and face recognition anti-theft door, computer login, e-government and e-commerce regarding information security. With the further maturity of technology ...
