Embodiment 1

[0058] figure 1 It is a schematic flow chart of this embodiment, a method for processing yin and yang faces of human face images, including,

[0059] Step 101, acquiring a first human face image, and performing a yin and yang face judgment on the first human face image;

[0060] It should be noted that before processing the yin-yang face of the human face image, it is first necessary to confirm the existence of the yin-yang face problem. In order to improve the detection rate of the yin-yang face, the detection steps of the yin-yang face in this embodiment also include:

[0062] Step 1011, obtaining face image information, and converting the first face image into a color image;

[0063] It should be noted that the face image information obtained in this step is a face recognition model u...

Embodiment 2

[0096] Image 6 A schematic structural diagram of a processing system for a Yin-Yang face of a human face image provided by the present invention, including:

[0097] Obtaining and judging unit 201, configured to acquire a first human face image, and perform Yin and Yang face judgment on the first human face image;

[0098] The first correction unit 202 is used to correct the first human face image by starting the combination of wavelet illumination compensation and LBP to obtain the second human face image if the first human face image is determined to be a yin and yang face;

[0099] The second correction unit 203 is used to calculate the LBP histogram of the rotation inconvenience uniform mode for the first human face image, obtain the LBP histogram of the first human face image, and apply the LBP histogram of the first human face image to the second In the face image, a third face image is obtained;

[0100] Wavelet fusion unit 204: for performing wavelet fusion on the sec...

Abstract

The invention provides a method and a system for processing the bright and dark faces of a face image. The method comprises the following steps: acquiring a first face image and judging the bright anddark faces of the first face image; if the first face image is judged to have a bright and dark face, starting the method of combining wavelet illumination compensation and LBP to modify the first face image to obtain a second face image; calculating an LBP histogram of a rotation-inconvenient uniform mode for the first face image, obtaining an LBP histogram of the first face image, and applyingthe LBP histogram of the first face image to the second face image to obtain a third face image; performing wavelet fusion of the second face image and the third face image to obtain a fourth face image. The invention solves the technical problem that the existing technology of face image recognition cannot effectively remove the bright and dark faces and cannot effectively complete the correction of the bright and dark faces.

Description

technical field [0001] The invention relates to the fields of face image processing technology and computer vision, in particular to a method and system for processing yin and yang faces in a face image. Background technique [0002] In recent years, with the rapid development of computer technology, the market demand for face image recognition information technology continues to hit new highs, and the research in the field of face image recognition has made great progress. Face image recognition is widely used in fields such as fund payment, access control system, attendance system, and target person tracking based on the particularity and uniqueness of a single living body's biological characteristics. [0003] While the face recognition algorithm has been widely used, its performance is still affected by many factors such as illumination, viewing angle, occlusion, and age. As a key factor affecting the recognition performance of the system, illumination changes are due t...
