Improvement of Apparent Motion Smoothness with Motion Lines

Abstract

Motion lines have been studied as expression of motion in static images. We investigated an effect of motion lines in apparent-motion displays. The smoothness of two-frame apparent motion was enhanced by presentation of a motion line between the frames, and even by simultaneous presentation of a motion line attached to an object in the first or the last frame. We additionally proved that the effect of motion lines becomes highlighted with an extended distance between apparent-motion components. The use of motion lines may contribute to production of various types of movies from the point of smoother motion impression with reduced computational load.
