Aim of the system is to develop a field programmable gate array based edge detection system. The proposed system calculates horizontal edge, vertical edge, left diagonal edge and right diagonal edge of gray scale image. Synthesizing and Simulation results and proposed Sobel edge detection system on Xilinx Spartan3 XC3S200 FPGA chip demonstrate the efficiency of proposed architecture for edge detecting of gray scale images for real-time image processing applications.

Keywords: Vhdl, Sobel Algorithm, Edge Detection, FPGA.
