Abstract :
In this paper we preset implementation of an optimized Sobel edge detection algorithm on FPGA. The optimized gradient based edge detection method reduces the area up to 48.76% compared to existing gradient calculation unit, and also reduces propagation delay up to 51% compared to the area optimized architecture. The entire project is implemented on Spatran-3E FPGA board. VGA interface is used to display the edge detection image on the monitor.
