The High-level video analytics PC sub-system as PCIe add-in card had been developed for surveillance, retail marketing tool and various applications which require acceleration of computer vision analytics for real-time video. The demo shows the sample application that detects many faces and optical flows. This PC sub-system can handle wide angle video and multiple videos (e.g. FHD, VGA x 6ch) in real-time. PC load average will be significantly mitigated so that it enables high-level video analytics and/or other applications using almost all of CPU resources. The SDK works on Windows platform; further functionalities will be developed as optional libraries.
