  • Abstract
    The author considers the shifts produced by mode filters on curved boundaries and contours. It is shown that these are similar to those produced by mean and median filters, the cases of linear intensity variations and of step edges being somewhat different and at opposite extremes of a continuum. Thus, shifts are intrinsic to basic neighbourhood averaging techniques, and can be avoided only by specially designed operators
