| Abstract:Image edge detection is used to extract image features, and provides basic processing in image segmentation, image recognition, face recognition and other technologies. In order to improve the accuracy and real-time performance of edge detection, this paper analyzes the algorithm of image processing edge detection, compares the advantages and disadvantages of the algorithm by Matlab simulation, and concludes that the Edge detection effect of Canny algorithm is better. The edge detection experiment of Canny algorithm is carried out by FPGA development board. From the experimental results, it can be seen that, The edge detection effect of Canny algorithm is more obvious, and the edge detection information is more, which can play a better role in the application. |
