Embodiment 1

[0488] Embodiment 1: based on face recognition sign-in system (such as Figure 9 )

[0489] Face authentication is the most friendly authentication method in the biometric authentication technology that has received widespread attention recently. It has the advantages of not being easy to forge, not being lost, and being convenient. This system uses face information to automatically verify people's identities. The face detection module used in it is the research result of this paper. In addition, this system also participated in the FAT2004 contest organized by ICPR2004. A total of 13 face recognition algorithms from 11 academic and commercial institutions including Carnegie Mellon University in the United States, the Neuroinformatik Institute in Germany, and the University of Surrey in the United Kingdom participated in the competition. The system submitted by our laboratory won the first place with a result of about 50% lower error rate than the second place in the three...

Abstract

The invention provides an eye precision orientation technology in the field of human face identifying. It is characterized in that it provides an eye precision orientation method on complex background image. It adopts a micro structure character with high efficiency and high redundant to express eye mode local and area grey distributing character and uses AdaBoost computing method to choose the most differential micro structure character to form the strong classer.

Description

technical field [0001] A method for locating eyes in complex background images belongs to the technical field of face recognition. Background technique [0002] The problem to be solved by the method proposed by the invention is the precise positioning of the eyes after obtaining the position information of the human face. Eye precise positioning is a key technology of face information processing, which is widely used in face recognition, human-computer interaction, intelligent human-computer interface and other systems. Precise eye positioning in complex backgrounds is also a very challenging problem. In addition to the complex changes in the appearance of the eyes due to factors such as illumination, size, posture, plane rotation, and image quality, the opening and closing of the eyes, the reflection of the glasses, the occlusion of the hair and the frame, etc. also bring the precise positioning of the eyes. Many difficulties; especially when the eyes are closed, the eye...
