Abstract
Abstract A correlation operational apparatus for multi-dimensional images includes: means for reducing at least two-dimensional components of the multi-dimensional images composed of at least two components by at least one component by projecting a vector representing the image onto a space perpendicular to a vector representing a large variance of distribution of the multi-dimensional image in a vector space whose orthogonal axes represent the individual dimensional component values of the multi-dimensional image; and means for performing a correlation operation for each component on the multi-dimensional images whose dimensional components have been reduced by at least one. In consequence, images having a relatively high number of high spatial frequency components and whose components have been reduced by at least one are extracted, and a correlation operation is performed thereon.
