There is also GridFlow, which has strong capabilities of analysis. However
you should download the latest via CVS, as it is much more stable than the
latest archive 0.7.2. (version 0.8.0 will be released in September)

in GridFlow, getting frame differences on a video stream is as easy as
plugging a video stream into [t a a] into a [@ -] with wires crossed,
which is a quite natural technique to a PD user. GridFlow extends simple
numeric concepts to whole pictures.
