Part of the Smart Innovation, Systems and Technologies book series (SIST, volume 32)

Abstract

Edge attribute Extraction is an indispensable and central subject in computer vision. In topical years edge detection performance has progressively been widely used because it filter out hopeless data from the image. Sobel edge detection is one of the classic edge detection operator, used to distinguish the edge pixels in an image and property of less weakening in high level of noise. This method exploits modify in intensity with respect to neighboring pixels in the image. The gradient edge detection is preferred in order to optimize the area which is crucial feature. For the purpose of reducing the FPGA area resource Sobel edge detection is implemented in VDHL and simulation and synthesis will be done using Xilinx.
