With the abilily to develop profesional visible light module and dual camera module, providing professional level office attendance, access control management and other office product development by using Baidu face recognition algorithm. Courseware Module Supporting Strong Backlighting: Monocular and Binocular Face Algoithms: Baidu
Using infrared LED lamp, in any light complex environment, near infrared camera can provide accurate image for face recognition algorithm; Baidu algorithm can quickly realize the determination of living body.
There are three methods to transform color image into gray image: maximum method, average method and weighted average method.
The collected images are processed through geometric transformations such as translation, transposition, mirror, rotation and zoom in order to correct the systematic errors from the image acquisition system.
The purpose of image enhancement is to improve the quality of face image, make the image clearer in vision, and make it easier to recognize.
The goal of normalization is to normalize face images with the same size and gray scale.
