11. An image processing apparatus for classifying each of a plurality of regions in an image to one of a plurality of predefined classes using classification confidences, the apparatus comprising: a confidence generation means for generating, for each of a plurality of regions of the image, a set of classification confidences, each classification confidence corresponding to one of a plurality of predefined classes and representing the probability of the respective region belonging to the predefined class; and a classification means for classifying the regions in the image, wherein for each of the regions of the image for which an obvious match with one of the predefined classes exists based on the classification confidences associated with the region, classifying the region to the respective predefined class based on the classification confidences associated with the region, the image processing apparatus further comprising: a fuzzy region extraction means for extracting and designating as fuzzy regions one or more regions of the plurality of regions, which do not have an obvious match with one of the plurality of predefined classes based on their set of associated classification confidences; and a confidence update means for updating the classification confidence for each such fuzzy region based on the sets of classification confidences associated with adjacent regions thereof, wherein the classification means further classifies the fuzzy regions to respective predefined classes based on the updated classification confidences.
