AI Technical Summary

Problems solved by technology

The existing embedded face recognition system generally has a relatively large image search area, and the search time of the embedded system is also relatively long, which leads to a corresponding decline in the real-time performance and operating speed of the system.

Embodiment Construction

[0022] The present invention will be further described below in conjunction with embodiment:

[0023] An embedded face recognition system is composed of six sub-modules: image acquisition, skin color pre-check, image pre-processing, face detection, face recognition, and database management module. The specific process is as follows:

[0024] (1) Image acquisition: use the camera as the image sensor, connect it to the embedded device through the USB interface, grab a chapter of face images through the camera or directly select a chapter from the hard disk, and then store the face image data source in the database;

[0025] (2) Image preprocessing: including grayscale transformation, binary transformation, noise reduction processing, and then using the method based on Adaboost to detect and locate the face, if the face is detected, it is stored in the database;

[0026] ①Gray scale transformation: use 0~255 to represent the gray level of each point, 0 is black, 255 is white;

Abstract

The invention relates to an embedded face recognition system. The embedded face recognition system is composed of an image collecting submodule, a skin color prechecking submodule, an image preprocessing submodule, a face detecting submodule, a face recognition submodule and a database management submodule. According to the characteristic of the embedded system, the skin color checking processing is added, the size of a picture searching area is reduced, the searching time of the embedded system is shortened, the real-time performance of the system is improved, an the running speed of the system is increased.

Description

technical field [0001] The invention relates to the technical field of face recognition, in particular to an embedded face recognition system. Background technique [0002] Identity recognition and identity authentication have very important application value in modern society. Due to the continuous improvement of network and informatization in today's society, information security in daily life has become more and more important, and people have to prove their identity almost all the time. [0003] Face recognition technology is of great significance in maintaining national security and the safety of people's lives and property, as well as in counter-terrorism and anti-terrorism. It is one of the most outstanding capabilities in human vision. With the gradual improvement of face recognition technology, face recognition technology has begun to develop into portable and mobile embedded systems. The existing embedded face recognition system generally has a relatively large i...
