Simulation for Helium Atom Scattering From Stepped Surfaces
-- A computer program has been developed to simulate the helium atom scattering from stepped surface for both up hill and down hill scattering with diffraction kinematics chosen to...

Streaming Surface Reconstruction Using Wavelets
We present a streaming method for reconstructing surfaces from large data sets generated by a laser range scanner using wavelets. Wavelets provide a localized, multiresolution rep...

A variational approach to spline curves on surfaces
Given an m-dimensional surface in Rn , we characterize parametric curves in , which interpolate or approximate a sequence of given points pi and minimize a given energy functio...

Analytical methods for polynomial weighted convolution surfaces with various kernels
Convolution surface has the advantage of being crease-free and bulge-free over other kinds of implicit surfaces. Among the various types of skeletal elements, line segments can be...

Beyond Lambert: Reconstructing Specular Surfaces Using Color
We present a photometric stereo method for non-diffuse materials that does not require an explicit reflectance model or reference object. By computing a data-dependent rotation of...
