Statistical Study on Cortical Sulci of Human Brains
A method for building a statistical shape model of sulci of the human brain cortex is described. The model includes sulcal fundi that are defined on a spherical map of the cortex. ...

Spectral LPM: An Optimal Locality-Preserving Mapping using the Spectral (not Fractal) Order
For the past two decades, fractals (e.g., the Hilbert and Peano space-filling curves) have been considered the natural method for providing a locality-preserving mapping. The idea...

Four Points in Two or Three Calibrated Views: Theory and Practice
Suppose two perspective views of four world points are given and that the intrinsic parameters are known but the camera poses and the world point positions are not. We prove that t...
