PURPOSE:To improve the processing speed and accuracy of an extracting device for connection component of 3-dimensional images by resolving a 3-dimensional image into plural 2-dimensional images to extract the connection components of each 2-dimensional image and at the same time obtaining the connection of the 3-dimensional image from the key point of each 2-dimensional connection component. CONSTITUTION:A 2-dimensional image input part 11 slices a 3-dimensional body to obtain plural 2-dimensional images. A 2-dimensional image key point extracting part 13 obtains the connection component of each 2-dimensional image through labeling processing carried out by a 2-dimensional labeling processing part 12. Then the part 13 obtains the key point from each 2-dimensional connection component. If the connection is obtained between 2-dimensional images for the obtained key point, all 2-dimensional connection components including said key point are extracted as a 3-dimensional connection component. |
