The subject of this paper is the semantically based postprocessing of
color-coded images such as classification results. We outline why the
classical definition of mathematical morphology suffers if it is used for
processing of coded image data. Therefore we provide an extension for
morphological operations such as dilation, erosion, opening, and closing. With
a new understanding of morphology we introduce bridging and tunneling as
further combinations of dilation and erosion. The extensions are applied to
medical image data, where the semantic rules stem from basic anatomical
