Video Edge Detection using MATLAB Simulink 2

Simulink-based video processing demos using DSP Blockset. All demos are based on R13 (MATLAB 6.5) 1: vid_edge.mdl Shows edge detection computation using the Prewitt method, applied to the red color channel of the same video sequence used in the motion detection videos. Follow the instructions in the model to compile the C code in the S-Function Builder blocks. The model will not execute unless the two S-Functions have been properly compiled. With the simulation running, open the "Edge Detection" block and adjust edge detection threshold and direction. This example highlights the use of the S-Function Builder block, which easily integrates user-supplied C code into Simulink.
