Detailed Description

A Michelson contrast channel, computes Michelson contrast in an image patch.

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. Michelson contrast in every map pixel is computed as abs( (La-Li) / (La+Li) ) where La is the local patch luminance and Li the average image luminance.
