AI Technical Summary

Problems solved by technology

The usual experimental results show that SVM has a better recognition rate, but it requires a large number of training samples (300 per class), which is often unrealistic in practical applications
Moreover, the support vector machine takes a long time to train, and the method is complicated to implement. There is no unified theory for the method of this function.

Embodiment Construction

[0039] Such as figure 1 As shown, the fast face recognition system of the present invention includes:

[0040] The lip pattern image acquisition unit is used to read the face image data of a person, and first collects the lip pattern image at the same angle;

[0041] The facial image data obtaining unit is configured to detect the face except the lips in the lip kiss image based on the facial image data obtained by the lip line image collecting unit, and detect the detected face from the complex background image captured above. Detect the face attribute of the object and extract the face image of the person;

[0042]Extracting the face image of the person includes calculating and identifying its boundary, which includes the following calculation process:

[0043]

[0044] Among them, k mn Represents the gray value of the image pixel (m,n), K=max(k mn ), shooting angle θ mn ∈[0,1]

[0045] Use the Tr formula to perform radian grayscale transformation on the image:

Abstract

To reduce the complexity of a face recognition algorithm, the invention provides a quick face recognition system based on personalized features especially lip images. The system reads face image dataof a person. Lip images at the same angle are collected at first, and then identification is conducted on the basis of a lip in the lip images and image data of other parts.

Description

technical field [0001] The invention belongs to the technical field of face recognition, and in particular relates to a fast face recognition system. Background technique [0002] Face recognition refers specifically to computer technology that uses analysis and comparison. Face recognition is a popular computer technology research field, face tracking detection, automatic adjustment of image magnification, night infrared detection, automatic adjustment of exposure intensity; ) to distinguish individual organisms by their own biological characteristics. [0003] Face recognition technology is based on the facial features of a person, and the input face image or video stream is processed. First judge whether there is a human face, if there is a human face, then further give the position, size and position information of each major facial organ of each face. Based on this information, the identity features contained in each face are further extracted, and compared with know...
