Abstract

This paper presents a novel approach to selecting appropriate scales in morphological opening­closing scale­space. It is based on a morphological band­pass filter that decomposes an image into structures of different size and different curvature polarity ("light and dark blobs"). Appropriate scale is defined as the scale that maximizes the response of the bandpass. The resulting scale measurements allow to automatically select window sizes (scales) for segmentation operators. The application of this idea to region segmentation gives very satisfying results.
