System for compressing and decompressing multidimensional images, capable of efficiently decompressing images without assurance of equivalence in pixel or frame

摘要

A multidimensional image compression and decompression system wherein, during compression, regardless of how high or low the pixel density is in an image used as an object for processing image data, compressed image data is obtained by extracting only characteristic points included in the image. During decompression, luminance data of pixels except those corresponding to characteristic points are determined by an interpolational plane or solid body which in turn is determined by a plurality of adjacent characteristic points when a position and luminance value of the characteristic points are used for transmission, recording and restoration of images, with respect to image data distributed in two-dimensions and three-dimension when a time base is included. Therefore, it is possible to decompress the multidimensional compressed image using only a short calculation time.
