Standard Gray Scale Images Users Manual.
Abstract
The CCITT is now in the process of developing standards for the transmission of gray scale, or continuous tone, monochromatic imagery as part of the Group 4 facsimile recommendations. The digital transmission of gray scale imagery is of particular importance to the government for the transmission of photographs, half-tones, maps, etc. Unfortunately, at the present time there is no standard set of gray scale images which can be used by all experimenters in the facsimile field. The purpose of this project is to develop such a set of standard images and provide them in digital form on magnetic tape of facsimile experimenters for use in the development of gray scale techniques to be considered for standardization. The tapes are available from the NCS. The purpose of this manual is to describe the format and content of the image tapes in sufficient detail so that a user can make use of the information on the tape easily. (Author)
