Recommendation ITU-T T.24 : Standardized digitized image set

Test images have played an important role throughout the development of Group 3 and Group 4 facsimile. This digitized test chart set has been prepared with the goal of providing a standard set of images to facsimile experimenters. The set includes images that have been used over the years plus new images that are applicable for gray scale and color. The standard set of images will provide a consistent baseline for further work; for example, results of compression algorithm experiments and image quality tests can be compared by a broad range of users, knowing that the input image data is identical.
This digitized test chart set is an integral part of Rec. ITU-T T.24 and is published with it.
A detailed description is given in T.24 for each test chart.
