Student military interpreters viewed nine vertical aerial photographs to judge their interpretability and to answer questions concerning their contents. Image quality was manipulated to produce 32 levels of degradation for each of the nine scenes. A single index called modulation transfer function area MTFA was used as the measure of image quality, and this measure was compared with image quality judgments and with photointerpreter performance in answering questions about image contents. Product-moment correlations between MTFA and interpreter performance averaged .72 for the nine scenes between MTFA and image quality judgments, they averaged .90 between quality judgments and performance, the average wa .70. As a criterion for imaging system evaluation and specification MTFA appears worthy of further exploration. Author
