The previous watershed methods results in over segmentation. In this paper we present a novel method for efficient image segmentation by using bit-plane slicing and marker-controlled watershed.  ...  Image segmentation is the basis for computer vision and object recognition. Watershed transform is one of the common methods used for region based segmentation.  ...  Regions of the image characterized by small variations in grey levels have small gradient values, so watershed segmentation is applied on the gradient of the image rather than the actual image.  ...

The watershed concept and its use in segmentation : a brief history [article]

Fernand Meyer
2012 arXiv   pre-print
The watershed is one of the most used tools in image segmentation. We present how its concept is born and developed over time.  ...  We present also how it is used in practice, first together with markers, and later introduced in a multiscale framework, in order to produce not a unique partition but a complete hierarchy.  ...  Such a hierarchy may be obtained in one run through the image, rather than repeating n increasing floodings and watershed basins detection. M.  ...
