Abstract
The author considers the shifts produced by mode filters on curved bou ndaries and contours. It is shown that these are similar to those prod uced by mean and median filters, the cases of linear intensity variati ons and of step edges being somewhat different and at opposite extreme s of a continuum. Thus. shifts are intrinsic to basic neighbourhood av eraging techniques, and can be avoided only by specially designed oper ators.
