Graphic/Symbol Segmentation for Group 4 Facsimile Systems.

摘要

The purpose of this study was to examine possible techniques for segmenting a document into graphic and symbol areas, and assemble a code that represents the entire document. Parameters to be considered include compression, commonality with facsimile and TELETEX* transmissions, and complexity of implementation. Six segmentation technique were selected for analysis. The techniques were designed to differ from each other as much as possible, so as to display a wide variety of characteristics. For each technique, many minor modifications would be possible, but it is not expected that these modifications would alter the conclusions drawn from the study. (Author)
