Is traffic police monitoring manual or face recognition technology?
Introduction:
Face recognition is a biometric technology for personal identification based on facial feature information.
Face recognition is to use a camera or video camera to collect images or video streams containing faces, automatically detect and track the faces in the images, and then perform a series of related application operations on the detected face images. Technically, it includes image acquisition, feature location, identity confirmation and search.
2021March 15 CCTV 3. 15 party exposed Kohler bathroom store's face recognition function camera to capture face information, which led to personal privacy leakage.
The traditional face recognition technology is mainly based on visible light images, which is also a familiar recognition method and has been developed for more than 30 years.
However, this method has insurmountable defects, especially when the ambient illumination changes, the recognition effect will drop sharply, which can not meet the needs of the actual system. There are three-dimensional image face recognition and thermal imaging face recognition to solve the illumination problem. However, these two technologies are far from mature, and the recognition effect is not satisfactory.
A rapidly developing solution is multi-light source face recognition technology based on active near-infrared images. It can overcome the influence of light change and achieve excellent recognition performance. The overall system performance exceeds that of 3D face recognition in accuracy, stability and speed. This technology has developed rapidly in recent two or three years, which makes face recognition technology gradually practical.
