Line-Scan Imagery Interpretation
article
An image interpretation experiment involved the interpredictability of line-scan pictures. Care was taken to use stimulus material fabricated with equipment whose transfer characteristics were well defined. System parameters as used in the experiment are given by the Modulation Transfer Function. Stimulus material thus obtained was presented to trained photo interpreters for various tasks (detection, discrimination, depth estimation). Results were analysed as a function of two experimental variables: level of degradation, and stereo versus non-stereo presentation. Curves show the deterioration of PI accuracy with increasing degradation. Stereo presentation proved to be of very limited usefulness: it seems to increase accuracy only for typical heigh estimation tasks in conjunction with moderate degree of degradeation. This limited advantage of stereo presentalion is obtained at a cost of an overall increase in time spent at the tasks
