The accurate segmentation of the bone from Magnetic Resonance (MR) images of the hip is important for clinical studies and drug trials into conditions like Osteoarthritis. This paper presents an automatic segmentation scheme that utilises a deformable model robust to different field of views by training shape priors from partial and full bone surfaces. The deformable model with these priors were used...
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...
