• #### 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 ...
• #### Wavelet-domain Approximation and Compression of Piecewise Smooth Images ﻿

(2006)
The wavelet transform provides a sparse representation for smooth images, enabling efficient approximation and compression using techniques such as zerotrees. Unfortunately, this sparsity does not extend to <i>piecewise ...
