This paper presents a new technique to generate triangular mesh surface parameterization and characterize 3-D surfaces by invariant spherical harmonic shape descriptors of objects with spherical topology. First, the surface is initially parameterized by defining a continuous one-to-one mapping from the surface of the object to the surface of a unit sphere. Then, the initial parameterization is optimized...
This paper introduces an integrated two-steps segmentation algorithm in the framework of Mumford-Shah functional. Note that the efficiency and convergence speed of the active contour-based segmentation algorithms are strongly dependent of selections of initial curves. Therefore a preprocessing step is introduced and integrated to construct an initial level set which is very closer to the boundaries...
