FPGA Implementation for Image Edge Detection using Xilinx System Generator

Abstract

Edge detection of an image is the primary and significant step in image processing. Image edge detection plays a vital role in computer vision and image processing. Hardware implementation of image edge detection is essential for real time application and it is used to increase the speed of operation. Field Programmable Gate Array(FPGA) plays a vital role in hardware implementation of image processing application because of its re-programmability and parallelism. The proposed work is FPGA implementation of image edge detection. The hardware implementation of edge detection algorithm is done using the most efficient tool called Xilinx System Generator(XSG).‘Xilinx System Generator’ (XSG) tool is used for system modeling and FPGA programming. The Xilinx System Generator tool is a new application in image processing, and offers a model based design for processing. The algorithms are designed by blocks and it also supports MATLAB codes through user customizable blocks. This paper aims at developing algorithmic models in MATLAB using Xilinx blockset for specific role then creating workspace in MATLAB to process image pixels and performing hardware implementation on FPGA.
