processing mask:  You define a processing mask in the Feature Map process to identify which portions of an image to include in the Feature Mapping analysis, and which to exclude.  The processing mask can be as complex as you like.  For instance, you can outline an irregular area in an airphoto to include, but exclude lake surfaces in that area, and yet include islands in the lakes.  (See also: mask)
