A Control Unit for a Motion Detector based on Histograms

A motion detector system searches in a sequence of video frames for information that reveals movement on the monitored scene. Motion detection can be used in many applications such as for surveillance, human motion analysis, vehicle and pedestrian detection and tracking and in robotics. A motion detection system based on histograms was developed. The system acquires and digitizes video frames from a video camera and stores the digitized data in RAM memory. The digitized pixel data is integrated on the horizontal and vertical directions providing the respective horizontal and vertical histograms. The histograms can be compared frame to frame and when a movement occurs in the scene, a noticeable difference on the histograms will appear on the correspondent spatial region of the image. In this paper we present the control unit for the developed motion detector.
