35 Let A be an initial label image.
36 Let B be a label image with an object.
37 Let o be an orientation relatively to the B object (for example RightTo, AntTo, InferiorTo ...)
39 This filter removes (=set background) from A all points that are
40 not in the wanted o orientation. It uses downsampled version for
41 faster processing, and (try to) take into account discretization
42 problem. Uses [Bloch 1999].
