ABSTRACT:
A recursive video blur effect is obtained by inserting a lowpass filter into a recursive feedback loop. Each pass of an output video signal through the recursive feedback loop successively smears the image represented by the video signal so that, when combined with an input video signal to produce the output video signal, a smoky fade effect is produced.
