Medical images are primarily gray scale with wide range of intensity inhomogeneity. The segmentation of these images gives rise to a lot of problems. Usually active contour models have been widely used to segment images with intensity inhomogeneity. It is defined by a contour and two approximation functions. This energy function is subjected to level set formulation to cope up with the topographical changes. A kernel function is introduced so as to guide the contour on a controllable scale. This method ensures regularity of the level set function and also prevents unwanted re-initialization of the energy term. Experimental results for various types of medical images with varying scale parameters show the performance of our method is desirable.
