The purpose of this effort is to investigate the more advanced Mixed Mode coding technique which will be one service of Group 4 facsimile. In a mixed mode system the information printed on a page is divided into two parts - symbols letters, numerals, punctuation, etc. and graphics logos, signatures, sketches, etc.. This study examines possible techniques for segmenting a document into graphic and symbol areas, and assemble a code that represents the entire document. Four segmentation techniques were selected for analysis as follows SYMBOL REMOVALSCAN LINE SYMBOL REMOVALLINE OF SYMBOLS EXTENDED TELETEX SYMBOL REMOVALHYBRID. These 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
