Abstract:

This report describes the preparation of an imagery data base containing 250 transparencies, consisting of 25 degraded versions of each of 10 digitized images. The 25 degraded versions consist of 5 blur levels combined with 5 noise levels. Each image is 86 mm square and represents 4096 x 4096 8-bit pixels. These images have corresponding ground truth, and the blur and noise levels are verified and quantitatively known. Subsequent stages of the research program will use these images in experiments to compare image quality with measured photointerpreter performance. An overview of the research program is also provided.
