Abstract :
Imaging faithfully in a dynamic environment is very challenging due to the severe degradation caused by the persistence of the display medium (phosphor). In target tracking applications, the degradation may make it impossible to detect an object. The degradation, takes place in all spatial frequencies of an input image. In this work, we propose to compare the amount of degradation caused when a raw image is displayed to that of when the edge image of the same object is displayed. The motivation of this work is to limit the input image to a specific range of frequency, so that a fixed filter may be used to undo the effect of motion degradation. A second motivation is that the motion degraded edge image may be psycho-physically perceived better by the observer than just the degraded raw image
