Abstract

The embodiment of the invention provides a cross-age face recognition method and equipment, and the method comprises the steps of determining a face feature vector, and decomposing the face feature vector into a first feature parameter and a second feature parameter, wherein the first feature parameter is not influenced by the age change of the face, and the second feature parameter changes along with the age change of the face; establishing a cross-age face recognition model according to the face feature vector, the first feature parameter and the second feature parameter; training the cross-age face recognition model based on face feature vectors and ages corresponding to face images in a cross-age face database to obtain a target cross-age face recognition model; inputting the face feature vector of the to-be-recognized face image into the target cross-age face recognition model, determining whether the target face image matched with the to-be-recognized face image exists in the cross-age face database or not and the identification information of the to-be-recognized face image, so that the recognition accuracy of cross-age face recognition is effectively improved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of face recognition, and in particular to a method and device for cross-age face recognition. Background technique [0002] As an important biometric identification technology, face recognition has been more and more widely used. [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 significantly improved with the development of deep learning technology, face recognition across ages is still very challenging. Since cross-age face recognition has irreplaceable value in many scenarios, such as searching for lost children or long-term wanted criminals, face comparison under long-term intervals, etc....
