【発明の名称】データ伸長システムとその方法及びデータ圧縮・伸長システム
Document Type and Number:
Japanese Patent JP3115632
Kind Code:
B2
Abstract:
Data decompression of an image is implemented by reconstructing blocks of pixels from a table that stores orthogonal icons and related attributes representing a data compressed image. Each block of pixels is processed independently of all other blocks. Orthogonal processing is employed to reconstruct orthogonal features that relate to manufactured elements in an image. An optimum set of orthogonal icons and an optimum set of attributes for each icon are employed to further improve data decompression 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. The optimal set of attributes includes average intensities, intensity transition position and separation, and angle of the principal axis.
