Abstract

This paper introduces a novel edge detector based on a new operator - the extended Russ operator - first introduced by J. C. Russ, based on the work of H. E. Hurst. One of the components of the extended Russ operator has been found to be edge sensitive. It has been used to good effect to pre-process mammograms before they are submitted to a conventional Canny edge detector. The resulting images provide an unbroken skin line and good detail in the nipple region, sufficient to facilitate further segmentation with ease. Although computationally demanding, it has the scope to be developed into an edge detector in its own right, once the theory behind its effectiveness is investigated further.
