Abstract :
This paper presents a complete system to detect scratches in rolls of photo paper. The idea is to use a group of white LED to illuminate the picture and highlight the scratches only. The system mainly consists of a camera to obtain images from the paper and an Altera DE2-70 FPGA Board to process those images. We can show that observing the scratches by applying specific filters on the acquired image makes the detection very simple and reliable.
