Abstract

The invention discloses a face recognition image processing method, which comprises the following steps: obtaining an identity card face photo of a person to be recognized with time parameters and a real-time face image with time parameters and environmental parameters at the same time; extracting human face features in the identity card human face photo with time parameters and human face features in the real-time human face image with time parameters and environmental parameters; calculating an identity card face feature autocorrelation coefficient, and at least adding a time parameter function to the identity card face feature autocorrelation coefficient to serve as a specific use condition; calculating an on-site face feature autocorrelation coefficient according to face features in the real-time face image, and at least adding a time parameter function and an environment parameter function to the on-site face feature autocorrelation coefficient to serve as specific use conditionsof the on-site face feature autocorrelation coefficient; and identifying the identity of the person to be identified according to the identity card face feature autocorrelation coefficient and the on-site face feature autocorrelation coefficient. The invention further discloses a system corresponding to the method.

Description

technical field

[0001] The invention relates to a face recognition image processing method and system. Background technique

[0002] Chinese invention patent CN201710139212.1 discloses a face recognition processing method and system. In this patent technology, there are defects in face recognition based on joint Bayesian, that is, two photos assumed to be input in face recognition (Associated objects to be identified) are symmetrical and identically distributed, so ID card face recognition cannot be fully utilized. Therefore, the above-mentioned technology uses different distribution face recognition between ID card chip face photos and on-site real-time face images. It is confirmed that multiple covariance matrix parameters are calculated by training a large number of face photos, and at the same time, the parameters are obtained by using high-definition ID card photos to assist training, which improves the accuracy of recognition and scene adaptability. In its specific imp...
