Digital Imagery Test Set.
Abstract
This exploratory development provides the initial concepts for a digital imagery test set from which subsequent detailed specifications would result. The difficult questions of image evaluation and quality were explored with the following categories of performance suggested for the test set criteria; amplitude response, frequency response, geometric fidelity, and noise. Both subjective tests with an experienced photointerpreter and objective tests using test pattern concepts were made. Computer programs were generated to simulate digital imagery degradations for the subjective tests, and these programs could be extended to include sensor simulations. The use of Moire' patterns provided simple objective tests as a result of the array structure of 2-dimensional digital imagery. Further development is recommended in exploring the tradeoffs between MTF response and aliasing distortion. (Author)
