Edge detection in textures—maxima selection

Abstract

This paper continues the analysis contained in [L. Davis and A. Mitiche, Computer Graphics and Image Processing 12, 1980, 25–39] concerning the design of edge detection procedures for textures. Edges are detected in textures by a combination of thresholding edge operator responses and then choosing local maxima of the surviving points. The thresholding step was analyzed in the paper mentioned above. Here, we analyze the effects of neighborhood size on the computation of local maxima. The analysis indicates that only small neighborhoods are required to attain reliable local maxima selection. This result is consistent with experience with real images.
