Experimental Studies on a Compact Storage Scheme for Wavelet-Based
Multiresolution Subregion Retrieval
Abstract.
Wavelet transforms, when combined with quantization and a suitable
encoding, can be used to compress images effectively.
In order to use them for image library systems,
a compact storage scheme for quantized coefficient wavelet data
must be developed with a support for fast subregion retrieval.
We have designed such a scheme and in this paper we provide
experimental studies to demonstrate that it achieves
good image compression ratios, while providing a natural indexing
mechanism that facilitates fast retrieval of portions of the image at
various resolutions.
