Embodiment Construction

[0075] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0076] Such as figure 1 The schematic flow chart of the first embodiment of the shown face detection method of the present invention includes:

[0077] Step S101: performing LBP feature calculation on the acquired image to obtain an LBP feature map;

[0078] Specifically, LBP is an effective non-parametric image local texture description method, which is simple to calculate and can capture trace details in the image, so as to extract local domain relation patterns...

Abstract

The embodiment of the invention discloses a method for detecting a human face. The method comprises the following steps of: carrying out LBP (Length Between Perpendiculars) characteristic calculation on an acquired image to obtain an LBP characteristic pattern; distinguishing the LBP characteristic pattern by using an AdaBoost classifier trained based on LBP characteristics to obtain first human face region data; carrying out Haar characteristic solving on the first human face region data to obtain an Haar characteristic pattern and distinguishing the Haar characteristic pattern by using the AdaBoost classifier trained based on the Haar characteristics to obtain second human face region data; clustering the second human face region data and combining the overlapped human face regions to obtain fourth human face region data; and outputting a human face region in the image. The embodiment of the invention also discloses a device for detecting the human face. According to the method and the device disclosed by the invention, the detection rate of human face detection is greatly increased; the false detecting rate is reduced, high detection speed is obtained, an interframe human face tracking step can also be added and further the detection speed is increased and the requirements of users on high detection rate and high detection speed are met.

Description

technical field [0001] The invention relates to the field of computers, in particular to a face detection method and a face detection device. Background technique [0002] Face recognition specifically refers to computer technology that uses analysis and comparison of facial visual feature information for identity identification. Face recognition is a popular computer technology research field. It belongs to biometric identification technology, which is to distinguish individual organisms by their own biological characteristics (generally referring to people). [0003] With the continuous development of electronic technology, the application of face recognition is becoming more and more extensive. Face recognition technology is used in access control systems, digital cameras, video surveillance systems, and network applications. Among them, after face recognition has become an essential function of digital cameras, cameras have also begun to use face recognition technology ...
