Abstract

Visual pattern image coding (VPIC) is a flexible image coding device offering excellent visual fidelity at high compression ratios with unprecedented, extremely low coding complexity. Hierarchical visual pattern image coding (HVPIC) schemes which achieve significantly increased compression (approaching 35:1) with improved fidelity and the very low complexity associated with VPIC are described. HVPIC employs standard VPIC embedded in a multiresolution (pyramid) structure. Low-resolution images coded at the upper levels augment coding of the higher-resolution images. Interactions between resolution levels is simple and efficient, yielding little increase in complexity relative to VPIC
