Generation of two-dimensional background noise by using computer

The purpose of this paper is to present the approach to get the two-dimensional background noise with the desired statistical nature by using a computer. This approach gives the picture of the desired two-dimensional background noise by applying the specific filter to the white Gaussian random noise. The filter function is obtained by the mathematical analysis. Since the center value of the filter function becomes infinite, the filter function is modified partially to be able to use actually. Several digital images with the desired statistical nature are generated by this approach. And it is verified that the generated images have the desired statistical parameters.
