摘要

PROBLEM TO BE SOLVED: To provide a method and a device for image data processing.

SOLUTION: The method of representing a data distribution derived from an object or an image by processing signals corresponding to the object or the image comprises a stage of recursively deriving an approximate representation of a first data distribution derived from the data distribution and a stage of analyzing the errors of data elements as a second data distribution expressed in terms of the approximate representation. The data elements are multi-dimensional, and the approximate representation is a partial space of a data space. The partial space is derived by using main component analysis, and the analysis of the errors includes clustering.
