Paper Title: Design of Sobel operator based image edge detection algorithm on FPGA
Published by: IEEE
Abstract: Real-time image processing applications requires processing on large data of pixels in a given timing constraints. Reconfigurable device like FPGAs have emerged as promising solutions for reducing execution times by deploying parallelism techniques in image processing algorithms. Implementation of highly parallel system architecture, parallel access of large internal memory banks and optimization of processing element for applications makes FPGA an ideal device for image processing system. Edge detection is basic tool used in many image processing applications for extracting information from image. Sobel edge detection is gradient based edge detection method used to find edge pixels in image. This paper presents a design of a Sobel edge detection algorithm to find edge pixels in gray scale image. Xilinx ISE Design Suite-14 software platforms is used to design a algorithm using VHDL language. MATLAB software platform is used for obtaining pixel data matrix from gray scale image and vice versa. Xilinx FPGAs of family Vertex-5 are more suitable for image processing work than Spartan-3 and Spartan-6.

Paper Title: Image Edge Detection using Sobel Operator Based on FPGA
Published by: Elsevier Publication
Abstract: Image processing algorithm implemented in reconfigurable device like FPGA have
emerged as most viable solution for improving performance of image processing systems. On FPGA
highly parallel system architecture can be implemented to achieve real-time requirement of system
and processing element can be optimized for the application. Edge detection is a fundamental tool
used in image processing applications to extract information from image frames. Sobel edge detection
is method to find edge pixel in an image. This paper presents the design of gradient based edge
detection algorithm using Sobel operator on reconfigurable device FPGA. VHDL language is used to
developed edge detection algorithm. This paper focused on edge detection of gray scale image.
