This paper is concerned with a new parallel thinning algorithm for three-dimensional digital images that preserves the topology and maintains their shape. We introduce an approach of selecting shape points and outer-layer used for erosion during each iteration. The approach produces good skeleton for different types of corners. The concept of using two image versions in thinning is introduced and...
The development of a microcomputer-based system for the automatic counting of colonies of indicator organisms (that is, bacteria whose presence is indicative of the presence of pathogens) trapped on membrane filters from water samples is described here. Three different approaches, based on mathematical morphology, distance transform and fuzzy c-means clustering respectively, are implemented and their...
