FPGA-based Road Traffic Videodetector

Abstract

In the present paper the background generation and motion detection algorithms, which are of key importance for the implementation of videodetection, have been presented. A modification of the background generation algorithm, essential for proper algorithm functioning at medium and high road-traffic conditions, has been proposed. Algorithm adaptation for the implementation in reprogrammable device has been also presented. A modification of the SAD algorithm, used in motion detection, has been introduced. The modification allows for regions of interest of irregular shape and structure in the analyzed image. It creates a capability to conduct the calculations in independent and parallel manner for specific, user-defined, active videodetection regions. PixelStream-based implementation has been successfully performed. Real-time verification on reconfigurable platform has been done.
