Body dynamic recognition-see monitoring image recognition "masked" people

China will become the world's first to masked or facial of video surveillance images for individual identification.

Yesterday, tieling City Public Security Bureau 213 Li Wei, Deputy Director of the Institute, through human dynamics for individual identification of 2 key technology, has won the national invention patent.

Li Wei revealed that, in past cases detected, the monitor video imaging information provided, often suspect masked or image is not clear but cannot make the identification of individual recognition, thereby losing evidence.

Through the human dynamics of identity technology, successfully solved this problem. "Each person posture when action are not the same, we would be in human biological characteristics can be used to identify the key characteristics of the extracted, and then in the database for gait characteristics than on for identification. "These features include: joints, bone and muscle characteristics. "Human dynamic recognition" compared to others, such as fingerprints, DNA identification technology has a non-invasive, non-contact, it is difficult to hide and camouflage, ease of acquisition, etc., and it is currently the case in distance only perceptual for identification of biological characteristics.

In Li Yue, Wei, this project is the most difficult to solve also is not a technical level, but rather the establishment of a database.

"This requires a lot of time and Manpower, even if the focus is on human characteristics for entry is also a huge project. ”

In July this year, the Institute for scientific research group 213 completed 300 cases of live video testing, sampling, and video data software change is complete, access to the underlying data and statistics, "now this technology can be applied to the cases detected.

"Li Wei said. When the police locked after a suspect, if collected radiological field target suspect information through system on two groups of dynamic characteristics of the various indicators compare values, you can figure out the suspects and target suspect is the same person.
