Abstract
A four-dimensional labeling apparatus that labels a four-dimensional image composed of time-sequentially juxtaposed three-dimensional images or a four-dimensional image produced with four parameters as a base, includes a four-dimensional labeling device for, when a four-dimensional domain is four-dimensionally scanned, determining the label number of a pixel concerned on the basis of label numbers assigned to pixels contained in a four-dimensional neighbor domain.
