ABSTRACT:
Two-dimensional tomographic image data is binarized by a predetermined threshold value, and two-dimensional labeling numbers are sequentially given to areas formed by binarization. Data of adjacent tomographic images are bit-added to generate data of a double bit length. When a value of this doubled-bit data appears at a frequency over a predetermined value, it is determined that corresponding areas of the adjacent tomographic image data are connected three-dimensionally, and a three-dimensional labeling number is given.
