Detailed Description

A temporal correlation channel.

Note that in this channel, high 'salience' means low temporal correlation, i.e., lots of change. CAUTION: this channel will throw a fatal exception if your LevelSpec contains more than one level or if that level is different from the maplevel or if the deltas are non-zero.
