Abstract

This paper describes a study in which several progressive image transmission and reconstruction (PITAR) methods were used to evaluate the Logical Bit-Slice technique, which was developed during this study. As defined in this paper, a method identifies which pixels are to be manipulated and a technique defines how those pixels are to be manipulated. The objective was to determine an efficient technique of extracting partial image information to improve image reconstruction. The measure was to identify which method resulted in the most recognizable image sequence with the least number of transmitted bits. The Logical Bit-Slice technique was incorporated into classical methods, e.g., Zig-Zag method, to create respective modified methods, e.g., Zig-Bit method. A feature of the Logical Bit-Slice technique is that it enables the signal-to-noise ratio of the reconstructed image to be adaptively set to a user- determined values. The principal conclusion was that incorporation of the Logical Bit-Slice technique into existing methods improved PITAR performance with minimal additional processing and complexity. Furthermore, the modified Block method, i.e., the Block-Bit method, provided superior visual reconstruction of high-contrast images.
