ANALYSIS OF METHODS FOR EDGE DETECTION

ŠŤASTNÝ, J.; ŽLEBEK, P.

Abstract

The paper describes the application of algorithms for edge detection in images. Edge detectors seek to find in an image a sharp change in the intensity of image function. Edges are formed by points where brightness changes abruptly. Edge detection in an image is closely connected with image processing and preprocessing. The application program therefore includes an adjustment of brightness and contrast, gray scale transformation, several filtering methods and histogram operations.
