Adaptation of Brensen s Thresholding Algorithm for Sketched Line Drawings

Abstract

Image binarisation is one of the first image processing techniques within a sketched line drawing interpretation system. In order to achieve an automated system, it is necessary to have a single algorithmwhich may be used for all image types. This is difficult to obtain if the parameters required by an algorithm are set manually, however, the adaptive evaluation of parameters form image properties is a step towards this goal. This paper discusses the methods by which the parameters required for Brensen s Algorithm may be evaluated adaptively form the image properties.
