https://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.45.5446
The signal is divided into frames which are subjected to a Fast Wavelet Transform, with subsequent fractal coding of high frequency wavelet coefficients using a collage approach. Results from initial implementations are examined. Compression ratios above 6:1 should ultimately be attainable with good fidelity signal reconstruction. 1 Introduction Over the past …

Wavelet Compression - an overview | ScienceDirect Topics
https://www.sciencedirect.com/topics/computer-science/wavelet-compression
Wavelet compression improves the contrast between the signal and noise components when determining the number of components by purity ratio. The reduction in the size of the data set and improvement in signal-to-noise ratio achieved through wavelet compression allow MCR methods to be applied faster on smaller computer devices and concomitantly improve the …
