Standard Bi-Level Images
Abstract
The purpose of this project was to generate a new set of standard images that can be used by experimenters developing bi-level compression algorithms. The NCS sponsored the scanning of documents used by the International Telegraph and Telephone Consultative committee (CCITT) at resolutions of 200, 240, 300, 400 and 480 lines per inch and stored the resultant data on tape. This data has been used by many experimenters in the development of standard compression algorithms for digital facsimile. This work contributed significantly to the development of high resolution facsimile standards which will be of considerable value to the U.S. Government. The purpose of compiling a standard set of bi-level images is to make the results presented by various experimenters in the field directly comparable, without regard to differences in image content. As a result of this project, all experiments engaged in performing studies for the CCITT regarding bi-level transmission techniques will have access to magnetic tapes or DOS diskettes containing digitized versions of the standard images. In addition, the images will be useful in evaluating graphic printer quality and capability.
