A fast level set method for inhomogeneous image segmentation with adaptive scale parameter

It is difficult to segment images in the presence of intensity inhomogeneity due to the overlap of the intensity ranges between different object regions. To deal with this problem, this paper presents a novel level set method to segment inhomogeneous images. Based on the inhomogeneous image model, an optimal segmentation plane is derived in image domain to provide the optimal partition for every pixel. With the plane, a new region-based pressure force function is proposed and used to define an energy functional in the level set formulation on the whole image region.
