Abstract
A region segmentation apparatus for segmenting an image into a plurality of regions by pixel data clustering comprises a clustering processing unit that clusters each pixel configuring the image to one of a plurality of representative data items based on respective pixel data. Based on pixel data belonging to each representative data item as a result of the clustering by the clustering processing unit, the plurality of representative data items used in the clustering are updated for a next clustering. The region segmentation apparatus further determines whether by the clustering a state in which a dead cluster should be resolved occurs, and, if it is determined that the state in which the dead cluster should be resolved occurs, changes representative data corresponding to the dead cluster to resolve the state.
