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)

图像融合技术，对可见光图像与红外图像进行融合。(Image fusion, image visible and infrared image fusion.)

该论文提出了一种改进的扩展卡尔曼滤波方法，实现对红外，雷达传感器的信息融合跟踪算法。性能优于传统EKF(This paper presents an improved extended Kalman filter method, to achieve the infrared, radar sensor information fusion tracking algorithm. Better performance than traditional EKF)

能够提取出图像I的HOG特征，返回其幅值，角度和在各个角度上的幅值。 是进行其他针对图像的HOG特征提取的前一步。(I can extract images of HOG features, return to their amplitude, angle and perspective in all of the amplitude. Is the other for image feature extraction HOG step forward.)

获得目标的颜色直方图，并利用巴氏距离比较两颜色直方图间的相似性。(Get color histogram)

快速非局部均值，用来消除噪声，效果良好，适合于细节较多的图像(Fast nonlocal means is used to eliminate noise and achieve good results, which is suitable for more detailed images.)

说明：  性能上比经典分水岭有很大的提高。特别对于自然图像的分割，效果特别好。(Performance than the classical watershed have greatly improved. Especially for natural image segmentation, the effect particularly good.)

基于BoVW的图像特征提取，以及图像检索(Image feature extraction and image retrieval based on BoVW)

近两年关于图像检索的重要参考文献，包括IEEE和国内CNKI上发表的顶级期刊(Image Retrieval over the past two years on the importance of references, including the IEEE and domestic CNKI top journals published)

Arnold变换和Logistic混沌映射的数字图像加密算法MATLAB源代码。将第一行图片路径换位要加密的图片运行即可。(Digital Image Encrypti Algorithm based on Arnold Tranform and Logistic Chaotic Maps)
