说明：  进行三维去高后，根据sar参数信息，将斜距转变为地距。(After performing three-dimensional height removal, the slope distance is converted to ground distance according to the sar parameter information.)

用小波去噪，不同尺度下的阀值去噪，去噪效果的对比(With wavelet denoising threshold denoising different scales, denoising effect contrast)

如题，里面有414张人脸图+matlab 图像重构代码和图像主成分代码(As the title says, there are 414 face pictures in it.+Model of image rebuild +Pca for Image code)

压缩包展示了对含高斯噪声和椒盐噪声图片去噪处理的基本去噪演示，包括均值滤波、中值滤波、维纳滤波、小波滤波。希望可以对初学的朋友有所帮助。(Basic denoising with Gaussian noise and salt and pepper noise image denoising demo, including mean filter, median filtering, Wiener filtering, wavelet filter)

使用K近邻算法对一个2维德样本集进行分类，样本集的分布为混合高斯分布。(K nearest neighbor to use a 2 Verde sample set for classification, the distribution of sample set for mixed Gaussian distribution.)

实现在matlab环境下的直线检测，效果很好，请大家试试。(Realize in the matlab environment linear detection, the effect of good, please try everyone.)

求信噪比的MATLAB源代码 很实用的函数(Signal to noise ratio for the MATLAB source code is very useful function)

主成分分析程序,应用于图像特征提取，数据降维等方面 (the code of PCA)

可同时实现多幅图片的傅里叶能量谱统计与分析！得到相应通道能量的信息！(Multiple images to achieve the power spectrum of Statistics and analysis!)

基于matlab的高斯金字塔算法，和一般的算法不同，此算法非常详细，逐步编写(Gaussian pyramid matlab-based algorithm, and the different algorithms, this algorithm is very detailed, step by step to prepare)
