They have given rise to a class of surfaces calledsubdivision surfaces. These have many advantages over traditional Non UniformRational B-spline (NURB) surfaces. Subdivision surfaces easily addressthe issues related to multiresolution, refinement, scalability and representationof meshes. Many schemes have been introduced that take a

In this study these methods are utilized as a pre-processing step to the Weibull E-SD field segmentation. It is demonstrated that the combination of the concentration edge detection and Gegenbauer reconstruction method improves the accuracy of segmentation for

It is semi-automatic and consists of two phases. First, the initial seg- mentation is accomplished by voxel labeling using statistical max- imum likelihood estimation techniques. The novelty of the present approach is that the type probability distribution function is not re- quired a priori. A multi-parameter distribution which includes

These data are very dense and make data-set manipulation difficult and
