Abstract

For accurate region extraction, region-based active contour models (ACM) have been proposed. Compared with ordinary ACM, they require heavier loads of initial settings and further processing time. Considering these problems, for effective and efficient extraction, we propose a new region-based ACM. In the proposed method, first, users draw an initial curve in an object. Along this curve, definite length scanlines are set perpendicular to the initial curve and across the object contour. Depending on the image properties around scanlines, the scanlines are separated into several groups and each group is divided into two subregions (object and background regions). Scanlines grouping and groups dividing are iterated until the image properties are sufficiently uniform in each subregion. Through this clustering, a region along an object contour is segmented into subregions of uniform image properties, and consequently the image properties in a necessary and sufficient area are introduced into extraction process effectively.
