Embodiment Construction

[0036] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0037] First, explain the technical terms that need to be used in this article:

[0038] Face registration (also known as facial feature registration): an image preprocessing method, mainly used for facial recognition. Changes such as scale, rotation and translation of facial images can be removed to meet the requirements of facial recognition.

[0039] Gamma correction: that is, the nonlinear gray level change logarithmic transformation or power rule transformation is used to replace the original gray level.

[0040] Gaussian difference filter: the difference between two Gaussian functions of different widths is used to generate a Gaussian difference filter, resulting in

[0041] The raw fo...

Abstract

The invention discloses an eye location method and a device, wherein the eye location method comprises: obtaining information of glasses of a facial image which is to be located,primary locating the eye position of the facial image according to the information of glasses, confirming the opening and closing state of the eyes of the facial image according to the primary located eye position, locating the eye position according to the opening and closing state of the eyes. The eye location method and the device solve the problem that the accuracy of eye location is poor in relative technology, eye location accuracy is improved and speed and accuracy of face identification are further improved.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a human eye positioning method and device. Background technique [0002] With the rapid development of information technology, the problem of information security has become increasingly prominent, and has become a key issue that must be solved in the development of technology. Among them, the identification of people is an important part of the field of information security. [0003] Face recognition is a biometric identification technology that verifies identity by extracting the features of the face. Compared with other biometric identification technologies, it has the characteristics of directness, friendliness and convenience. Therefore, in recent years, many researchers in the world have put a lot of research on identification and verification based on facial features. [0004] Face recognition is mainly composed of four parts: face detection, human eye positioning, facial ...
