Comparison between Various Edge Detection Methods on Satellite Image
Annapurna Singh, Anuj Kumar · 2013
In this paper the comparative analysis of different edge detection algorithms is presented. The edge is the basic characteristic of image. In an image, an edge is a curve that follows a path of rapid change in image intensity. Edges are often associated with the boundaries of objects in a scene. Edge detection is used to identify the edges in an image and significantly reduces the amount of data and filter out useless information, while preserving the important structural features in an image. This research paper presents a brief study of the fundamental concepts of the edge detection operation, theories behind different edge detectors and compares different image edge detection algorithms including Roberts, Sobel, Prewitt, and Canny with MATLAB tool.
