Area Efficient FPGA Implementation of Sobel Edge Detector for Image Processing Applications

Abstract: In this Paper an efficient method of FPGA based design and implementation of area efficient Sobel Edge detection filter is presented using a combination of hardware and software components. The FPGA provides the necessary hardware for image processing algorithms with flexibility to support Sobel edge detection algorithm. A pipelined method is used to implement the edge detection filter. This approach is useful to improve the system performance by taking advantage of available look up tables, routing resources … Show more

“…Most video and image processing Sobel edge detection algorithms (Nelson, 2000;Yasri et al, 2009;Mehra & Verma, 2012;Nosrat & Kavian, 2012;Singh et al, 2012;Umar et al, 2012;Bhagat et al, 2015) use the sum of the absolute values of the gradient in both the horizontal and vertical directions,…”

“…Lately, there have been several texts (Li & Chu, 1997;Nelson, 2000;Yasri et al, 2009;Mehra & Verma, 2012;Nosrat & Kavian, 2012;Sanduja & Patial, 2012;Singh et al, 2012;Umar et al, 2012;Bhagat et al, 2015) written on hardware-based Sobel implementations on FPGAs using VHDL (Ashenden, 2008) or Verilog. However, nearly all of these advocate the use of calculating the gradient magnitude by obtaining the sum of the absolute values of the gradient in both the horizontal and vertical directions.…”
