alpha稳定分布噪声的matlab实现

压缩感知Matlab代码实现，图像压缩采样，OMP重构(Compressed sensing code, image compression sampling, OMP reconstruction)

说明：  利用matlab对多光谱遥感影像进行水体指数（ndwi）以及植被指数（ndvi）提取(Extraction of Water body Index (ndwi) and vegetation Index (ndvi) from Multispectral remote Sensing Images by matlab)

经典的图像处理常用图片，包括Lina，Barbana, Cameraman(Classic image processing commonly used pictures, including Lina, Barbana, Cameraman)

K-Means算法,不要求建立模型之后对结果进行新的预测，没有相应的标签，只是根据数据的特征对数据进行聚类。主成分分析降维对数据进行可视化操作,对features进行降维.(K-Means algorithm does not require the establishment of the model after the new prediction of the results, there is no corresponding tag, but only on the characteristics of data clustering data. The principal component analysis reduces the dimension, carries on the visualization operation to the data, reduces the dimension to the features.)

改进的图像拼接算法，基于sift算法，实现图像的自动拼接，测试，完美运行(Improved image mosaic algorithm based the sift algorithm to achieve automatic image stitching, test, run perfectly)

new edge-directed interpolation这篇文章所提算法的matlab实现(new edge-directed interpolation algorithm in this article referred to realize matlab)

对CANNY算子进行改进，其中详细的分析了CANNY算子的原理，已经应用改进的canny算子进行边缘检测，效果较好(CANNY operator improvements, including a detailed analysis of the principle of CANNY operator has been applied to improve the canny operator edge detection, better )

生成静态散斑图，通过快速傅里叶变换，得到激光散斑图。(Generate static speckle pattern)

matlab模拟退火工具箱，包含模拟退火运行所需的各种函数，是模拟退火的一个非常有力的工具。(simulated annealing Matlab toolbox contains simulated annealing operation of the various functions, Simulated Annealing is a very powerful tool.)

很简单的基于颜色的图像检索系统，闲时做的(Very simple color-based image retrieval system at leisure to do the)
