Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] Figure 5 A specific implementation flow of the face recognition method based on template matching of the present invention is excluded.

[0027] Such as Figure 5 As shown, in step 10, normalization processing is performed on the face image after feature positioning. In this embodiment, the image can be cropped to a specified size according to the position of the eyes.

[0028] In step 20, the face image is transformed into the transformation domain, the shape and texture information of the image are enhanced, and the sensitivity of the face image to changes in illumination, expression and posture is reduced. There are many ways to transform the face image into the transform domain, such as Gabor transform, Gaussian transform, DCT transform, FFT transform and HARR transform. In this embodiment, Gabor transform is taken as ...

Abstract

The invention discloses a face identification method based on model matching, which comprises the following steps: transmitting the face to the changing region; doing LBP calculation of face image; extracting histogram from the LBP calculation result; accomplishing face identification through histogram matching. The invention improves the calculation speed, which reduces the sensitive degree of gesture, light, appearance and environmental variation.

Description

technical field [0001] The invention relates to a face recognition method in the field of pattern recognition, in particular to a face recognition method based on template matching. Background technique [0002] As one of the most successful applications in the field of image analysis and understanding, face recognition has received extensive attention in both commercial applications and research. Existing face recognition methods include face recognition methods based on template matching and face recognition methods based on statistical analysis. [0003] In the face recognition method based on template matching, the face image is usually encoded with a unified template, and then the face recognition is realized by matching between the codes. For example, in the face recognition method based on template matching, there is a face recognition method based on the local change distribution pattern. In this method, the LBP operation is performed on the image containing the fac...
