Abstract
A method of detecting a curvilinear object of a noisy image. The method includes filtering the noisy image in accordance with a two dimensional line profile. The line profile is selected within a class of steerable filters. A beamlet coefficient is calculated in accordance with the filtering, wherein a coefficient above a predetermined threshold identifies a local feature.
