Abstract
Cataloged from PDF version of article.In this work, a subband domain textual image compression
method is developed. The document image is first decomposed into
subimages using binary subband decompositions. Next, the character
locations in the subbands and the symbol library consisting of the
character images are encoded. The method is suitable for keyword search
in the compressed data. It is observed that very high compression ratios
are obtained with this method. Simulation studies are presented
