Embodiment Construction

[0026] The technical scheme of the present invention is described in detail below in conjunction with accompanying drawing:

[0027] The idea of ​​the present invention is to use a classifier fusion method that combines the classifiers trained on the features of local organs (such as facial features) on the face and the classifiers on the overall features of the face to construct a fusion classifier for gender recognition, thereby improving Recognition accuracy; 2DPCA method is used to reduce the dimension of the image, and 2DLDA is used as the classification method. On the basis of ensuring the detection accuracy, the calculation amount is reduced, and the training and detection speed are improved.

[0028] The gender recognition method based on face image of the present invention, specifically according to the following methods:

[0029] Step 1: Image preprocessing, sequentially grayscale the test image, histogram equalization and median filter processing, as follows:

[00...

Abstract

The invention belongs to the technical field or image processing and pattern recognition, and discloses a gender identification method based on a facial image. According to the gender identification method, a classifier fusion method that a classifier used for training features of local organs (for example, the five sense organs) on a human face respectively and a classifier of overall features of the human face are combined is used for establishing a fusion classifier for carrying out gender identification, so that the identification accuracy rate is improved; and since a two-dimensional principal component analysis (2DPC) method is used for carrying out dimensionality reduction on the facial image, a two-dimensional linear discriminant analysis (2DLDA) is used as a classifying method, on the basis that the detection accuracy is guaranteed, the calculation amounted is reduced, and the training speed and the detecting speed are increased.

Description

technical field [0001] The invention relates to a gender recognition method based on a human face image, belonging to the technical field of image processing and pattern recognition. Background technique [0002] Like other biological features, human face features are inherent to human beings, and they are unique and non-replicable. Because of such features, human faces provide the necessary premise for identity identification. Moreover, face recognition technology also has its unique advantages compared with other biometric technologies, such as concealed operation, which is convenient for safety monitoring; non-contact acquisition is easier to be accepted by users, and it is friendly; it has strong post-event tracking ability; The cost of acquisition equipment is low; it conforms to human recognition habits and has strong interactivity; it does not require too much professional knowledge and a series of advantages. [0003] Gender recognition is an application part of fac...
