Design and implementation of video image edge detection system based on FPGA

The purpose of this paper is to describe the difference between edge detection based on software and the full use of hardware resources within the FPGA. According to the video signal theory and edge detection algorithm, the author designs the IP core of video image edge detection and builds the video image edge detection system on the EDK. The hardware circuit of the algorithm is achieved on ISE9.1 and simulated in Model Sim 6.0. When the system is validated, it indicates that the video image edge detection system can detect high-precision edge.
