Abstract :
Applies frequency domain motion analysis to the explanation of the visual artifacts and of the aliasing of video signals. The authors review some fundamental notions of frequency domain analysis of motion. The effects of velocity and acceleration with respect to the introduction of visual artifacts are considered. The loss of signal information produced by motion is examined
