Abstract

The invention discloses a cross-age face recognition and model training method and device, a computer readable storage medium and an electronic device. The cross-age face recognition model training method comprises the steps of extracting feature vectors of face images in a cross-age face database through a convolutional neural network, wherein the cross-age face database comprises a plurality offace images classified according to age features and classification features of faces; obtaining a norm and a normalization vector of the feature vector, updating age loss corresponding to the norm based on the age feature of the face image, and updating classification loss corresponding to the normalization vector based on the classification feature of the face image; and training the convolutional neural network based on a joint loss of the age loss and the classification loss. Based on the scheme of the embodiment, the cross-age face recognition performance of the model can be improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method and device for cross-age face recognition and model training thereof, a computer-readable storage medium and electronic equipment. Background technique [0002] As an important biometric identification technology, face recognition has become a research hotspot in the field of image processing and pattern recognition, and has also been widely used in the fields of public security, human-computer interaction and identity authentication. [0003] In the practical application of face recognition, the face image to be recognized is affected by various external factors, such as illumination, occlusion, posture, expression, age, etc., among which the change of the face image due to age changes is particularly prominent. Although the accuracy of general face recognition has been greatly improved with the development of deep learning technology, face recognition across ...
