ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an information processing method, an information processing apparatus, and a computer-readable recording medium recording an information processing program. More particularly, the present invention is suitably used for transforming one multidimensional information pattern into another multidimensional information pattern and for inversely transforming the multidimensional information pattern having been transformed.
2. Description of the Related Art
Heretofore, Fourier transform, Laplace transform, etc. have been known as information transforming methods for transforming one multidimensional information pattern into another multidimensional information pattern and for inversely transforming the multidimensional information pattern having been transformed.
On the other hand, a model utilizing a multidimensional discrete information pattern (M. Creutz, Computer in Physics 5, 198(1991)) has been proposed as a model capable of being inversely transformed.
Furthermore, a diffusion process described by a diffusion equation or the like is known as a method for transforming one multidimensional information pattern into another multidimensional information pattern.
However, the above conventional methods and model have problems as follows. Fourier transform, Laplace transform, etc. can be used with relatively easy analysis because of using numerical formula expressed in the simple form, but they are restricted in applications because of linear transform.
The model utilizing a multidimensional discrete information pattern cannot handle a continuous value, and therefore input information must be processed into the discrete form before starting transform of the information. Some of information is lost upon the processing into the discrete form.
The diffusion process described by a diffusion equation or the like is applicable only to forward transform, but not to inverse transform. Accordingly, the diffusion process has a difficulty in maintaining the amount of input information as it is.
