The Contour Extraction Problem with Biomedical Applications.

Abstract

The approach presented here formulates the contour extraction problem as one of minimum cost tree searching. In particular, use is made of the Zigangirov-Jelinek (ZJ) stack algorithm. The approach is described first on an artificially contrived problem and then applied to two real biomedical image processing problems. The biomedical problems considered are concerned with the extraction of the left ventricular outline from serial angiocardiograms and the extraction of lung outlines from digitized chest X-rays.
