On Edge Detection

IEEE Transactions on Pattern Analysis and Machine Intelligence, 1986
Edge detection is the process that attempts to characterize the intensity changes in the image in terms of the physical processes that have originated them. A critical, intermediate goal of edge detection is the detection and characterization of significant intensity changes. This paper discusses this part of the edge detection problem. To characterize

Edge detection and motion detection

Image and Vision Computing, 1986
Abstract This paper presents an integrated theory of edge detection, curvature measurement and motion detection during the earliest stages of visual processing. No assumptions are necessary about the viewed objects or about surface properties and the viewing geometry.

A Computational Approach to Edge Detection

IEEE Transactions on Pattern Analysis and Machine Intelligence, 1986
This paper describes a computational approach to edge detection. The success of the approach depends on the definition of a comprehensive set of goals for the computation of edge points. These goals must be precise enough to delimit the desired behavior of the detector while making minimal assumptions about the form of the solution. We define detection

On Detecting Edges

IEEE Transactions on Pattern Analysis and Machine Intelligence, 1986
An edge in an image corresponds to a discontinuity in the intensity surface of the underlying scene. It can be approximated by a piecewise straight curve composed of edgels, i.e., short, linear edgeelements, each characterized by a direction and a position.

Edge Detection Revisited

IEEE Transactions on Systems, Man and Cybernetics, Part B (Cybernetics), 2004
The present manuscript aims at solving four problems of edge detection: the simultaneous detection of all step edges from a fine to a coarse scale; the detection of thin bars with a width of very few pixels; the detection of trihedral junctions; the development of an algorithm with image-independent parameters.
