ABSTRACT:
Image data compression is implemented by partitioning an image into relatively small blocks of pixels, matching each block to an orthogonal icon, and extracting attributes associated with the icon. A table of these orthogonal icons and attributes represents a data compressed image. Each block is processed separately from all other blocks. Orthogonal processing is used to preserve orthogonal features while attenuating non-orthogonal features. An optimum set of orthogonal icons and an optimum set of attributes for each icon further improves data compression and fidelity. The optimal set of orthogonal icons includes a flat icon, an edge icon, a ribbon icon, a corner icon, and a spot icon. An optimal set of attributes includes average intensities, intensity transition position and separation, and angle of the principal axes.
