The von Kries Hypothesis and a Basis for Color Constancy
Color constancy is almost exclusively modeled with diagonal transforms. However, the choice of basis under which diagonal transforms are taken is traditionally ad hoc. Attempts to...

Geodesics Between 3D Closed Curves Using Path-Straightening
In order to analyze shapes of continuous curves in R3 , we parameterize them by arc-length and represent them as curves on a unit two-sphere. We identify the subset denoting the cl...

Hippocampal Surface Analysis Using Spherical Harmonic Function Applied to Surface Conformal Mapping
Using spherical harmonics of an inverse conformal map, we compared hippocampal surfaces of sixteen Alzheimer (AD) and fourteen control subjects. Hippocampal surfaces were conforma...
