Abstract:

Two methods of inspecting pairs of comparison photographs were studied 1 side-by-side display and 2 apparent-motion display, in which pictures in spatial registry were presented in temporal alternation. This second presentation method produces apparent motion, where a difference between the pictures exists, which aids in the rapid detection of objects that have changed. Both experienced and inexperienced interpreters were tested with aerial photography varing in scale, contrast, resolution, and terrain complexity. Under certain conditions the apparent-motion display method was found to enhance significantly interpreter performance in the change detection task. However, it became relatively less effective with poorer quality imagery or where these was a high percentage of irrelevant change. Under difficult conditions, neither display method was significantly better than the other. Although the applications of the apparent-motion technique are limited, the results of this study suggest the value of further efforts to define the extent of its usefulness.
