According to Tsinghua News Network, recently, commissioned by the Ministry of Education, Tsinghua University hosted the “TH-IDvs†jointly developed by Tsinghua University Professor Ding Xiaoqing and jointly developed by Tsinghua University and Beijing Haixin Kejin High-Tech Co. Appraisal meeting of scientific and technological achievements of video surveillance face recognition technology and system.
After evaluation, the appraisal committee believes that the project has improved the face recognition technology level and system research and development capabilities of video surveillance in China. The main technical indicators of the system have reached international advanced and domestic leading levels, and they have unanimously agreed to pass the appraisal.
TH-IDvs Video Surveillance Face Recognition Technology and System Aimed at the difficulties of face recognition under the conditions of huge changes in motion, posture, lighting, etc. in video surveillance and low definition, through the use of time-domain filters and multi-view active representation models (Active Appearance Model (AAM) method for precise tracking of face feature points; a method of generating multi-illuminated face images from a single frontal light sample based on linear Lambertian characteristics; a priori combining dictionary learning and image self-similar Knowledge-based kernel regression image super-resolution reconstruction method; and a fast three-dimensional face reconstruction algorithm based on sparse feature points and L1 norm constraints, etc., which effectively solves the poses, lighting, expressions in complex backgrounds and dynamic videos Face recognition and authentication of video sequences under changing conditions such as visual angle, angle of view, motion, and image clarity have significantly improved the accuracy of face recognition with large pose changes.
The video face recognition system successfully developed by combining the above technologies overcomes multiple difficulties in practical applications, has superior recognition performance, and has been implemented on a large scale in the field of public safety. Beijing Haixin Company has undertaken the industrial promotion of technology, and the video surveillance face recognition alarm system jointly developed by the company has been successfully applied to the Shanghai World Expo, Guangzhou Universiade, Shenzhen High-Tech Fair, and the 8th Shenzhen Cultural Fair, etc .; and has been effectively applied to the public security field. The “Cleaning the Net†action for data tracing of persons hunted on the Internet and the identification information authentication and inquiry service of the National Citizen ID Card Number Inquiry Service Center have played an important role in maintaining national social security, creating outstanding social benefits and significant Economic benefits.
