Circumferential traversal techniques for characterizing shapes in digital images

Research output: Contribution to journalConference articlepeer-review


Characterizing of region shapes in digital images is a common requirement in medical image processing. This paper describes an approach based on successive traversals around the region boundary, enabling a sequence of related shape information at different scales to be constructed. The approach is useful in that it allows several different shape characteristics to be determined using the same set of data. The approach and its implementation is described, and an example of its application to a problem in bio-medical cell discrimination is considered and compared with results from more conventional shape characterization techniques.
