Morphological Difference Operation and Morphological Filtering of Image
Ming‐Shiang Wu · Huadong Shifan Daxue xuebao. Ziran kexue ban · 1992
A set of morphological difference operators based on basic operations of mathematical morphology (MDO) are proposed.The frequency response characteristics of some common operators (ED, DD, NLLP) are discussed.Experimental results demonstrating their usableness in image detection, edge extraction and binary thresholdization are given.
