| Abstract: | This paper presents a real-time edge detection system based on FPGA,using Veilog language to implement the system of data collection,storage and display.Aiming at the problem that the image edge detection affected by noise,this paper proposes a combination of median filtering and the improved Sobel edge detection preprocessing algorithm.Experimental results are compared with the results of the classic Sobel edge detection,which demonstrate the developed system has a strong image noise suppression and precis... |
