Representation and compression of multidimensional piecewise functions using surflets

Representation and compression of multidimensional 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 edges, video sequences of moving objects, and seismic data containing geologic...
