A Novel Decision Mechanism for Image Edge Detection

Abstract: Edge detection is one of the most important and fundamental problems in the field of computer vision and image processing. Edge contours extracted from images are widely used as critical cues for various image understanding tasks such as image segmentation, object detection, image retrieval, and corner detection. The purpose of this paper is to review the latest developments on image edge detection. Firstly, the definition and properties of edges are introduced. Secondly, the existing edge detection methods ar… Show more

“…It is well known that the accuracy of LSI has great influence over subsequent tasks of an input image in computer vision and image processing. As the basic structural feature of an image, image corner and edge are generally detected by using the first-order derivatives 25,27,44 , and blob are generally detected by using the second-order derivatives 45 . Next, examples of these three basic structural features detection are used to show our way to extract LSI from an input image, in which both the scale factor and the anisotropic factor are set to √ 1.5.…”

“…Edge detection [1] is a foundational task in image processing and computer vision. Edges refer to positions where the information of pixels change suddenly in gray or color images [2][3][4][5][6][7]. The information of edges is used in many image processing and analysis techniques, such as image segmentation [8][9][10], image retrieval [11][12][13], corner detection [14][15][16][17][18], etc.…”
