Non-Uniform to Uniform Grid Conversion Using Least-Squares Splines

Michaël Unser, Thierry Blu

We propose a new technique to perform nonuniform to uniform grid conversion: first, interpolate using nonuniform splines, then project the resulting function onto a uniform spline space and finally, resample. We derive a closed form solution to the least-s ...

Construction of Fractional Spline Wavelet Bases

Michaël Unser, Thierry Blu

We extend Schoenberg's B-splines to all fractional degrees α > -1/2. These splines are constructed using linear combinations of the integer shifts of the power functions x+αx _{ + } ^{ \alpha } (one-sided) or xα|x| _{ * } ^{ \alpha } (symmetric); in eac ...

One-Step Growth of Buried Heterostructures by Chemical Beam Epitaxy over Patterned Inp Substrates

Alok Rudra, Marc Ilegems, Jean-Daniel Ganière

We studied the formation of buried heterostructures obtained in a single growth step over nonplanar substrates patterned with ridges. When the ridge dimensions are large enough, the growth on the mesa top is similar to that on a planar substrate. In contra ...
