The Recognition of Sharp, Closely Spaced Edges

Abstract

The recognition of sharp edges from edge- and bar-mask convolutions with an image is studied for the special case where the separation of the edges is of the order of the masks' panel-widths. Desmearing techniques are employed to separate the items in the image. Attention is also given to parsing de-smeared mask convolutions into edges and bars; to detecting edge and bar terminations; and to the detection of small blobs.
