Abstract
A method for modeling a 2-dimensional tubular structure in a digitized image includes providing a digitized image of a tubular structure containing a plurality of 2D balls of differing radii, initializing a plurality of connected spline segments that form an envelope surrounding the plurality of 2D balls, each the spline segment Sbeing parameterized by positions of the iand i+1balls and contact angles α, αfrom the center of each respective ball to a point on the perimeter of each the ball contacting the spline segment S, each the αaffecting spline segment Sand S, and updating the angles by minimizing an energy that is a functional of the angles, where the updating is repeated until the energy is minimized subject to a constraint that the envelope is tangent to each ball at each point of contact, where the envelope is represented by the contact angles.
