COMPARISON OF THREE DIFFERENT IMAGE FORCES FOR ACTIVE CONTOURS ON ABDOMINAL IMAGE BOUNDARY DETECTION
ABSTRACT: Active contour, or
snake, is an energy minimizing spline that is useful in image boundary detection.
Active contours are stimulated by internal forces, image forces and external
forces which maintain the shape of the contours while attract the contours to
some desired features, usually edges. Problems in implementing active contours
such as convergence and initialization have motivated researchers to modify
image forces of the active contours. This paper presents a comparative study
among three different image forces: traditional snakes, balloon and gradient
vector flow (GVF). The study is validated by experiments on abdominal image
boundaries detection. These lead to the conclusion that GVF gives the most
appropriate results among the other approaches.
