Abstract

One of the most fundamental operators of mathematical morphology, the granulometry operator 驴 t assigning to a compact set (or to a grayscale function) its granulometric opening by a convex set, is generally considered to be upper semicontinuous but not continuous. We consider this a deficiency and intend to rectify it, mainly by an adjustment of convergence assumptions.
