Compressing Piecewise Smooth Multidimensional Functions Using Surflets: Rate-Distortion Analysis
(2004-03-01)Discontinuities in data often represent the key information of interest. Efficient representations for such discontinuities are important for many signal processing applications, including compression, but standard Fourier ... -
Compression of Higher Dimensional Functions Containing Smooth Discontinuities
(2004-03-01)Discontinuities in data often represent the key information of interest. Efficient representations for such discontinuities are important for many signal processing applications, including compression, but standard Fourier ... -
A Geometric Hidden Markov Tree Wavelet Model
(2003-08-01)In the last few years, it has become apparent that traditional wavelet-based image processing algorithms and models have significant shortcomings in their treatment of edge contours. The standard modeling paradigm exploits ... -
Geometric Methods for Wavelet-Based Image Compression
(2003-08-01)Natural images can be viewed as combinations of smooth regions, textures, and geometry. Wavelet-based image coders, such as the space-frequency quantization (SFQ) algorithm, provide reasonably efficient representations for ... -
Representation and Compression of Multi-Dimensional Piecewise Functions Using Surflets
(2006-03-01)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 ... -
Surflets: A Sparse Representation for Multidimensional Functions Containing Smooth Discontinuities
(2004-07-01)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 ...
