✦ Synopsis

The Hueckel edge detector is one of a class of edge detectors which operate by approximating the image input by a truncated series of orthogonal functions. The number of terms in the expansion determines the accuracy of approximation and also t, he complexity of the process. In this paper, effects of reducing the terms used for expansion are examined. Experimental results indicate a significant loss in performance by such simplifications.
