说明：  光谱数据降维处理，结合了主成分分析和LDA方法，可直接运行(Spectral data dimensionality reduction processing, combined with principal component analysis and LDA method, can be directly operated)

视觉slam十四讲，程序资料：g2o优化、cere拟合、特征点提取与匹配、点云拼接、opencv图像读取(Visual slam 14, program data: g2o optimization, cere fitting, feature point extraction and matching, point cloud mosaic, OpenCV image reading)

用于图像去噪处理Tikhonov模型，仅供用于学习参考(Tikhonov model for image denoising)

图像阈值分割，基于matlab的二维Renyi熵算法的灰度图像分割(Image threshold segmentation, matlab based two- dimensional Renyi entropy algorithm gray- scale image segmentation)

图像去雾算法质量评价标准：均值方差，峰值信噪比及平均梯度的源代码，还有引导滤波的完整源代码。(Image quality uation algorithm defogging criteria: mean and variance, the peak signal to noise ratio and average gradient of the source code, as well as guide the filter complete source code.)

说明：  CxImage是一款免费的、开源的、功能强大的图形处理库。 跨平台，支持windows、linux等；支持BMP、GIF、ICO、TGA、JPEG、PCX、PNG、TIFF、MNG、RAS等多种图像格式；支持格式转换、图像处理、几何变换等；最重要的是使用非常简单。此为VC6修正版(CxImage is a C++ image processing library. It can load, save, display, transform images in a very simple and fast way, with transparency, multiple layers and selections, support for BMP GIF JPG PNG MNG TIF ICO TGA PCX J2K JBG RAS PNM RAW PSD.)

本代码主要是基于HSV的阴影检测及消除，分别提取前景及背景图像，进行色彩空间转换。HSV空间类似人类感觉色彩的方式，可以更加准确地识别阴影，并保持在计算上简单。(This code is mainly based on the HSV shadow detection and elimination, extract the foreground and the background image, respectively, for color space conversion. HSV space is similar to the ways the human feel color, can more accurately identify the shadow, and keep it simple in calculation. )

关于图像处理程序，它能实现对破损图像的提取和修复，速度快( Image processing program, it can achieve the extraction and repair damaged images, fast)

国外写的knn-matting，图像抠图的源程序，有实例，可直接使用(knn-matting looking abroad to distinct the image layer, there are instances, can be used directly)

用于图像检测的正态分布计算的c代码实现，现在将这个函数写在头文件中了(Normally distributed computing for image detection of the c code, this function will now be written in the header file in the)
