Embodiment Construction

[0056]In the embodiment of the present invention, a face model training module based on Gabor features and support vector machines is first provided, including: a sample collection unit, which is used to collect positive samples and negative sample faces for each user who needs to be authenticated Image; preprocessing unit, used to preprocess all sample images according to the calibration of the facial organ feature point positions in all sample faces; feature calculation unit, used to calculate the Gabor of the preprocessed face image feature; a feature selection unit, used to select the part of the Gabor feature with the strongest classification ability from the high-dimensional Gabor feature obtained by calculation to form a low-dimensional feature vector; a model training unit, used to utilize the low-dimensional feature vector, using a pair of Multiple support vector machines are trained for different authenticated users, and a one-to-many support vector machine face model...

Abstract

The invention relates to a face model training module, relative method, and a face real-time identify system, and method, wherein in the identification, first using face sample image, to supply one face model supporting vector machine to each user; via collecting the video image input by camera, searching and checking the face of image, and tracking and identifying the image; then automatically marking the organ character point of face, to pre-treat checked face; calculating the Gabor character of face image after pretreatment; selecting low-dimension character vector from high-dimension Gabor character; inputting the selected low-dimension character vector into face model, to process face recognition, to feedback similarity data of each face model; based on said similarity data, outputting final face identifying result. The invention can improve the right rate of face recognition identification.

Description

technical field [0001] The present invention relates to a model training module and method of a human face image, and a real-time face authentication system and method, in particular to a face model training module and method based on Gabor features and support vector machines, and a real-time authentication system and method . Background technique [0002] Face recognition is to compare the input face image with the template in the known library and determine the degree of identity similarity. It is a very popular research topic in the field of computer vision and pattern recognition research. Compared with other biological characteristics (such as fingerprints, irises, DNA, etc.), using human faces for identification is more direct and natural. However, some other biometric features require an active information collection method, requiring the cooperation and cooperation of the user, which also brings inconvenience to the user. Face recognition adopts a passive informat...
