用二维随机数生成二维高斯分布随机表面，可调整均方差、相关长度等参数-Generate a two-dimensional Gaussian random numbers using two-dimensional distribution of random surfaces, adjustable both variance, correlation length and other parameters

matlab对图像随机添加四种噪声，然后分别通过自编中值滤波，均值滤波，高斯滤波，和维纳滤波进行滤波-matlab add four random noise to the image, and then were filtered by self median filtering, mean filtering, Gaussian filtering, and Wiener filtering

对模糊变量进行随机化,并用高斯分布进行概率求解,无密码-To randomization of fuzzy variables, and probability to solve with the gaussian distribution, no password

以matlab实现数字水印的生成和提取,用的是高斯随机序列-With matlab the generation and extraction of digital watermarking, using a gaussian random sequences
