Some recently developed tools for grey level image analysis are presented. We describe a new approach to segmentation, based on the watershed transformation and on the analysis of the morphological features of the regions created by the transformation. A skeletonization algorithm is also outlined, able to produce a one-pixel thick skeleton in presence of irreducible sets. Finally, we describe an algorithm to build a pyramid, where the information contents of the image, in terms of shape and topology, is preserved through lower resolution representations.

Abstract
Some recently developed tools for grey level image analysis are presented. We describe a new approach to segmentation, based on the watershed transformation and on the analysis of the morphological features of the regions created by the transformation. A skeletonization algorithm is also outlined, able to produce a one-pixel thick skeleton in presence of irreducible sets. Finally, we describe an algorithm to build a pyramid, where the information contents of the image, in terms of shape and topology, is preserved through lower resolution representations.File in questo prodotto:
