The goals of this paper are not only to reduce of noise using anisotropic diffusion filter post-processing but also to represent 3-D image using 2-D image slices by volume rendering. A 3D shape image can be obtained as the 2-D images are continuously acquired, during the object is removed noise by filtering. The 3-D shape images are displayed on computer monitor by use of OpenGL Software.

Shape modeling is an important part of computer vision. Shape models help the tasks of object representation and recognition. In this paper, curve evolution and level set algorithms are used for extracting a shape within an image. This method is based on the ideas developed by Osher and Sethian to model propagating solid/liquid interfaces moving with curvature-dependent speeds. We propose the new generalized formulation and stopping function of evolution for more accurate extraction of shape. Our method canbe applied to model arbitrarily complex shapes and has the ability to dynamically sense the topological changes of the shape during the shape recovery process.
