Fast and simple discrete approach for active contours for biomedical applications

In this paper, we present a fast and simple discrete approach for active co ntours. It is based on discrete contour evolution, which operates on the bo undary of digital shape, by iterative growth processes on the boundary of t he shape. We consider a curve to be the boundary of a discrete shape, We at tach at each point of the boundary a cost function and deform this shape ac cording to that cost function. The method presents some advantages. It is a discrete method, which takes an implicit representation and uses discrete algorithm with a simple data structure.
