<h3>Purpose</h3>

Provide combined background subtraction -- differential filter for on-line use.

<h3>Description</h3>

This filter provides background subtraction combined with differential
filtering for on-line use.

<h3>Algorithm</h3>

See \ref cfl_filterbgsplanar and \ref cfl_filterdifferential.

<h3>Examples</h3>
Try to find some interesting pictures for most filters.
