Optimality of Operator-Like Wavelets for Representing Sparse AR(1) Processes

Pedram Pad, Michael Unser

It is known that the Karhunen-Loève transform (KLT) of Gaussian first-order auto-regressive (AR(1)) processes results in sinusoidal basis functions. The same sinusoidal bases come…

Harmonic Singular Integrals and Steerable Wavelets in $L_{2} (R^{d})$

John Paul Ward, Michael Unser

Here we present a method of constructing steerable wavelet frames in $L_{2} (R^{d})$ that generalizes and unifies previous approaches, including Simoncelli's pyramid and Riesz…

Decay properties of Riesz transforms and steerable wavelets

John Paul Ward, Kunal Narayan Chaudhury, Michael Unser

The Riesz transform is a natural multi-dimensional extension of the Hilbert transform, and it has been the object of study for many years due to its nice mathematical properties. M…
