Open publisher page 0 citations

Abstract

Piecewise Constant(PC) model is one of the most popular region-based models in the existing active contours.It is actually devoted to the problem of piecewise-constant segmentation of images using the level set approach.This paper proposes a modified version of PC model in a Partial Differential Equation(PDE) formulation.The proposed model can handle the fast segmentation of images with piecewise-constant intensity,moreover,the number of iterations is significantly less sensitive to initialization of the contours.
