Accelerating Fractal Image Compression by Multi-Dimensional Nearest Neighbor Search
: In fractal image compression the encoding step is computationally expensive. A large number of sequential searches through a list of domains (portions of the image) are carried o...

Quantization of Overcomplete Expansions
The use of overcomplete sets of vectors (redundant bases or frames) together with quantization is explored as an alternative to transform coding for signal compression. The goal i...
