Embodiment Construction

[0034] like figure 1 The shown face recognition system includes four modules of face detection and positioning, normalization, feature extraction and face recognition in turn.

[0035] 1. Face detection and positioning module

[0036] It is an important step to judge the position of the face through the obtained samples, select a suitable face, and intercept it as a sample. The quality of face feature location and feature extraction has a direct impact on the effect of face image recognition. First determine the coordinates of the human eye (x 1 ,y 1 ) and (x 2 ,y 2 ), thus the coordinates of the upper left vertex and the lower right vertex of the square face can be obtained indirectly, assuming that they are respectively (X 1 , Y 1 ) and (X 2 , Y 2 ), the detailed calculation method is as follows:

[0037] Width eyes =x 2 -x 1 ;

[0038] Width face =Width eyes / R H ;

[0039] x 1 =x 1 -(Width face -Width eyes ) / 2;

[0040] x 2 =X 1 +Width face ;

Abstract

The invention relates to a face recognition system. The face recognition system comprises a face detection and positioning module, a standardization module, a feature extraction module and a face recognition module in sequence. The face recognition system has the advantages that the recognition accuracy can reach above 90%, and recognition requirements are basically met. The face recognition system is good in real-time performance, convenient to carry, and capable of being popularized to the fields of dynamic image tracking, motion detection and the like through modification of programs.

Description

technical field [0001] The invention relates to a face recognition system. Background technique [0002] The operation speed of the related algorithm of face recognition is slow, the acquisition and processing of PAL video signal and the operation of face positioning generally cannot be carried out independently from the PC, the face recognition equipment is bulky, heavy, high power consumption, and inconvenient to carry , all of which limit the application and promotion of the face identification system. Contents of the invention [0003] The technical problem to be solved by the present invention is: based on the above problems, the present invention provides a face recognition system. [0004] A technical solution adopted by the present invention to solve the technical problem is: a face recognition system, which sequentially includes four modules of face detection and positioning, normalization, feature extraction and face recognition. [0005] Further, the face dete...
