Analysis of the Performance of Morphological Edge Detectors with Respect to EdgeOrientation and Displacement

摘要

Mathematical morphology theory has been recently used as a basis for the proposalof new edge detectors in digital images. The purpose is to present an evaluation of the performance of six morphological edge detectors with respect to sensitivity of their response to edge orientation and edge displacement, in both horizontal and diagonal directions. One example of the application of one of these detectors for the delineation of linear features in urban areas of a LANDSAT image is also presented.
