The basic conception concerned with reduction of processing-time and memory-capacity in the use of a digital computer has already been shown by the author in the paper ”pattern Recognition by the codes of 3×3 elements and Karhunen Loeve Orthogonal System.” First of all, this paper says that a quantized pattern of 225 dimensions is transformed into a pattern vector of 9 dimensions, and secondly it shows the investigation of the relation among each vector. Furthermore, the author researches that the degree of the dependence Iij is defined on a set of the codes formed with 3×3 elements which construct pattern vector of law dimensions and that the degree of the dependence is related with the reformed pattern vector.
