Paper Abstract

Micro-Adaptive Picture Sequencing (MAPS) is a computationally-efficient, contrast-adaptive, variable-resolution two-dimensional spatial image coding technique. MAPS enhancements which smooth the processing rate and improve image quality in a manner compatible with direct image display are described. Rate smoothing allows the reconstructed image to be updated at the equivalent of one line per line. Image quality is enhanced in a manner which sharpens detail, preserves subtle (low contrast) extended features, improves representation in textured regions, and effectively reduces visual artifacts in the form of image 'blockiness' present with the basic MAPS decompression mode. Moreover, decompression operations maintain a strictly local character suitable for very fast implementation � potentially at video rates. Finally, in addition to visual improvement, significant quantitative (mean square) error reductions are observed with no change in MAPS compression level.
