使用中值，均值，小波，DCT，PCA五种方法实现对图像的去噪处理。(Five methods, median, mean, wavelet, DCT and PCA, are used to denoise the image.)

一种基于纹理特征分析的遥感图像分类C++程序(Based on the analysis of texture characteristics of remote sensing image classification C++ program)

计算Zernike矩，对图像进行了平移，尺度归一化(Computing Zernike moments, the image of the translation, scaling normalization)

对于空间两个点云，利用经典的icp算法进行匹配(ICP fit points in data to the points in model. Fit with respect to minimize the sum of square errors with the closest model points and data points. )

采用最小均方差法对虹膜瞳孔定位，虹膜外圆定位，归一化及其增强处理，圆拟合(Using least-mean-variance method of positioning the iris pupil, iris outer location, normalized and enhanced handling, circle fitting)

将保存有灰度图像信息的txt文件转化生成灰度图片。 txt数据只能包含数据，数据用逗号或者空格隔开，所存数据个数应与所生成的图片大小相同。例：要还原的图片大小为640*480，那么txt文件中就应当有307200个数据。(The txt file with information of grayscale image is transformed into gray image. The TXT data can only contain data, separated by commas or spaces, and the number of data stored should be the same as the size of the generated image. Example: the size of the image to restore is 640*480, so there should be 307200 data in the txt file.)
