Embodiment Construction

[0052] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0053] see figure 1 A schematic flow chart of a face positioning method according to an embodiment of the present invention is shown, including:

[0054] Step S101: Obtain the user's original image through the camera.

[0055] Specifically, after the user's original image is acquired, the user's original image is preprocessed, and the preprocessing includes noise removal, illumination equalization, and other preprocessing.

[0056] Step S102: Roughly locate the user's original image to obtain a roughly positioned face image.

[0057] Specifically, the user's original image is roughly detected and positioned by the Haar and AdaBoost algorithms, and then based on the skin color distribution characteristics of the f...

Abstract

The invention discloses a method for face location. The method comprises the steps of obtaining an original image of a user through a camera; carrying out rough location on the original image of the user to obtain a face rough location image; obtaining face detection area information according to the face rough location image, wherein the face detection area information comprises position information of all parts on the face; obtaining accurate shapes of all the parts on the face by means of the local shape fitting method according to the face detection area information. The invention further discloses a face location device. According to the method and device for face location, complexity of calculation is reduced and fitting accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of human-computer interaction, in particular to a method and device for face positioning. Background technique [0002] In the field of human-computer interaction, the detection and positioning technology of the user's face plays a vital role. [0003] Most of the existing face localization technologies operate with independent modules, rather than using a unified framework for processing. In terms of face feature point location technology, the prior art mainly uses the ASM (Active Shape Model, active shape model) model and its improved model, and its fitting accuracy is low. Contents of the invention [0004] The invention provides a method and device for face positioning, which improves the fitting accuracy. [0005] The invention provides a method for face positioning, comprising: [0006] Obtain the user's original image through the camera; [0007] Roughly locating the original image of the user t...
