符合高斯分布的关于随机粗糙表面的生成代码(Meet the Gaussian distribution of the random rough surface on the generated code)

程序包括三种经典的边缘检测方法，均可独立运行，参数可调(Program includes three classical edge detection methods can be run independently, adjustable parameters)

说明：  傅里叶变换中的角谱衍射理论，GS算法实现(Angle spectrum diffraction theory in Fourier transform, Realization with GS algorithm)

说明：  按照最邻近原则把待分类样本点分到各个簇。然后按平均法重新计算各个簇的质心，从而确定新的簇心。一直迭代，直到簇心的移动距离小于某个给定的值。(According to the nearest neighbor principle, the sample points to be classified are divided into clusters. Then the centroid of each cluster is recalculated according to the average method to determine the new cluster center. Iterate until the moving distance of the cluster center is less than a given value)

说明：  信息隐藏里LSB隐写方案的RS分析方法，附有详细注解。(Information hiding in LSB Steganography Scheme RS analysis, with detailed notes.)

经典主成分分析法，实现高光谱图像的降维处理 (Classical principal component analysis, to achieve high spectral image dimensionality reduction)

用MATLAB软件产生一个被高斯噪声污染的lenna图像，使用T3、T5、高斯滤波、中值滤波进行处理；(MATLAB software with a Gaussian noise pollution Lenna image, the use of T3, T5, Gaussian filtering, median filtering for processing )

将ENVI格式转换为tiff格式的IDL源代码，放在扩展程序下使用(Converts ENVI format to tiff format of IDL source code, under the extension)

sift和surf特征点提取，然后进行配准，通过ransac进行提纯(Sift and surf feature points are extracted, then registered and purified by RANSAC)

hausdorff距离的一种改进算法，是我自己编写的，用于提取焦点之后的图像配准(hausdorff distance of an improved algorithm, which I have written for the extraction of the focus after the image registration)
