摘要

本文的目的是提出一种利用计算机获得具有理想统计性质的二维背景噪声的方法。这种方法通过对高斯白随机噪声应用特定的滤波器，给出了期望的二维背景噪声的图像。通过数学分析得到了滤波函数。由于滤波函数的中心值变得无穷大，因此对滤波函数进行了部分修改，使其能够实际使用。通过这种方法生成了具有所需统计性质的若干数字图像。并验证了生成的图像具有所需的统计参数。

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.
