FY91 AASERT - Spatio-Temporal Masking in Human Vision and its Application to Image Coding
Abstract
We measured the temporal dynamics of relative motion Judgement. Two lines or dots oscillated either in the same phase of motion, or in 180 phase relative to each other. Subjects were required to discriminate between the two kinds of motion. The dots either oscillated vertically or horizontally. The former case produced oscillating orientation and the later case produced oscillating separation. The temporal frequency of oscillation was varied (presented at OSA-1992). In experiments with lines, the separation of the lines was varied while the distance of the lines from the fovea was held constant. The discriminability of two different phases of relative motion was measured and compared to the detectability of these motions. The physchometric transducer functions were measured and plotted.
