Title:
Watershed-Based-Segmentation-
Download
Description: In recent years, the watershed line has emerged as the primary tool of mathematical
morphology for image segmentation. Several very efficient algorithms have been
devised for the determination of watersheds. Nevertheless, the application of watershed
algorithms to an image is often disappointing: the image is oversegmented into
a large number of tiny, shallow watersheds, where one wanted to obtain only a few
deep ones. This paper presents a novel approach to watershed merging. Mainly, it
addresses the following question: given an image, what is the closest image that has
a simpler watershed structure? The basic idea is to replicate the process of watershed
merging that takes place when rain falls over a real landscape: smaller watersheds
progressively fill until an overflow occurs.
