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)
