invariant feature

a characteristic of an object that does not change when the object is viewed under different circumstances. Because invariant features are unaffected by manipulations of the object or the observer, they are powerful cues for object recognition by humans or machines. For example, when solid objects of different orientation are compared, the volume of the objects is an invariant feature.
