Real-time edge detection using dynamic structuring element

Abstract

The morphological gradient is the classical, useful tool in image edge enhancement, but it can be insufficient in real-time applications due its complexity, as are different modifications of this method proposed in literature to obtain clearer edge information. In this paper a novel, simple and fast morphological edge detector is presented. It is based on the definition of a non-flat, dynamic structuring element and on the new definition of a simple morphology operation, useful as a generalisation of many image processing operations. The several results of the algorithm's application are presented, as along with the results of its implementation in a real-time IR and TV image fusion hardware system. © Springer International Publishing Switzerland 2014.
