Variant code transformations for linear quadtrees
In this paper, general guidelines and specific algorithms for code transformations between breadth-first (BF) and depth-first (DF) linear quadtrees are proposed. Each algorithm ha...

A generalized de Casteljau approach to 3D free-form deformation
This paper briefly presents an efficient and intuitive 3D freeform deformation approach based on iterative affine transformations, a generalized de Casteljau algorithm, whereby th...

Capturing practical natural language transformations
We study automata for capturing the transformations in practical natural language processing systems, especially those that translate between human languages. For several variation...

Wavelet Steerability and the Higher-Order Riesz Transform
Abstract— Our main goal in this paper is to set the foundations of a general continuous-domain framework for designing steerable, reversible signal transformations (a.k.a. frames...

Nearly optimal sparse fourier transform
We consider the problem of computing the k-sparse approximation to the discrete Fourier transform of an ndimensional signal. We show: • An O(k log n)-time randomized algorithm f...
