Abstract
In a method of locating problem areas in an image signal (I), a motion vector field (Df) is estimated for the image signal (I), and edges are detected in the motion vector field (Df). In a corresponding method of interpolating images between existing images (I), image parts are interpolated (MCI) in dependence upon a presence of edges; preferably, an order statistical filtering (med) is used at edges.
