[0036] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to more clearly illustrate the technical solutions of the present invention, but cannot limit the protection scope of the present invention with this.
[0037] see figure 1 , in order to solve the problem that the face recognition effect of the above method is unsatisfactory under complex lighting conditions, the present invention proposes a more effective lighting estimation and lighting invariant extraction algorithm based on the classic and simple Lambertian model, so as to improve Accuracy of face recognition under complex lighting conditions. The present invention comprehensively considers the imaging principle of the image, the characteristics of slowly changing illumination and the complex illumination environment, and combines image fusion and smoothing filtering to propose an effective illumination estimation and illuminatio...
