AN OPERATOR WHICH LOCATES EDGES IN DIGITIZED PICTURES,

Abstract

The paper reports the development of an edge finding operator (subroutine) which accepts the digitized light intensities within a small disc-shaped subarea of a picture and yields a description of any edge (brightness step) which may pass over the disc. In addition, the operator reports a measure of the edge's reliability. A theoretical effort disclosed the unique best operator which satisfies a certain set of criteria for a local edge recognizer. The main concerns of the criteria are speed and reliability in the presence of noise. (Author)
