A Proposed FPGA Based Architecture for Sobel Edge Detection Operator
Tanvir A. Abbasi and Mohd. Usaid Abbasi

This paper presents a FPGA based architecture for Sobel edge detection operator. Typical use of Edge detection is in the artificial intelligence system. It has found application in forensic science and also in digital multimedia for creating image dazzling effect. Currently the image processing algorithms has been limited to software implementation which is slower due to the limited processor speed. So a dedicated processor for edge detection has been required which was not possible until advancement in VLSI technology. Now more complex system can be integrated on a single chip providing a platform to process real time algorithms on hardware. Sobel operator is chosen due to its property of less deterioration in high levels of noise.
