Surflets: A Sparse Representation for Multidimensional Functions Containing Smooth Discontinuities
Discontinuities in data often provide vital information, and representing these discontinuities sparsely is an important goal for approximation and compression algorithms. Little work has been done on efficient representations ...
Representation and Compression of Multi-Dimensional Piecewise Functions Using Surflets
We study the representation, approximation, and compression of functions in M dimensions that consist of constant or smooth regions separated by smooth (M-1)-dimensional discontinuities. Examples include images containing ...
