Simulink-based video processing demos using DSP Blockset. All demos are based on R13 (MATLAB 6.5) 1: vid_hist.mdl Shows real-time histograms of the R, G, and B color channels of a video sequence. 2: vid_sad.mdl SAD stands for Sum of Absolute Differences, and is a popular technique for motion detection in video. This demo shows a video sequence with motion detection applied independently to each of the four quadrants of the video; if motion in a quadrant is detected, that quadrant is highlighted with a red color as the video plays. Each quadrant is independent (hence 4 separate SAD computations are being computed). Note that either the difference image itself may be viewed, in place of the original intensity image, along with the red motion highlighting. This gives the user an idea of how the SAD metric works. 3: vid_srv.mdl Demonstrates a basic surveillance camera data-compression application. Only enables recording of video frames in which motion estimates rise above a threshold. In effect, it only records "scene changes."
