Abstract :
Industrial inspection cameras for Web processes have a very high output video rate. This output data rate can be reduced by preprocessing the video stream inside the camera in order to only send pixels that have a high probability of containing defect information. Co-occurrence matrices are quite successful in detecting structural defects in fabrics; however, they require high processing power. This paper discusses simplification to these algorithms, which are simple enough to fit into a medium-small size FPGA.
