NEC’s metadata search system enables fast and accurate searching for persons in huge surveillance video archives. The system includes automatic searching in response to real-time detection of suspicious individuals as well as offline searching defined by user-input images or descriptions.
Currently Real time and Offline Meta Search are under Research & Development and would be commercially available soon.
