说明：  线性判别分析（LDA）用于特征选择，可以对数据集或者图像提取有用特征，用于分类或者聚类等机器学习应用中(Linear Discriminant Analysis (LDA) for feature selection, application in dataset or image feature extraction, for classification or clustering applications in machine learning)

光学组件的matlab工具包，利用它，你可以仿真spot，几何像差，如慧差，球差，还有mtf仿真等(Optical components matlab toolkit, use it, you can simulation spot, geometric aberration, such as the Hui poor, spherical aberration, as well as simulation mtf)

内置虑镜功能，包括获取图像的属性，锐化，模糊，浮雕等功能． 可以缩放，优化图片．打开图片带预览功能,使用了gdiplus,能处理gif,bmp,jpg,png图片,处理速度也不错，呵呵,一直找图形格式转换的朋友就不需要东找西找了，它完全可以实现你的需求！ (Built-in lens into account features, including access to the properties of the image, sharpen, blur, emboss and other functions. Can be scaled to optimize picture. Open the image with the preview function, use the gdiplus, can handle gif, bmp, jpg, png images, the processing speed is not bad, huh, huh, graphic format conversion has been looking for friends do not need to look east and west, and it can achieve your needs!)

sobel segmentation, this algorithme has a great effect for segmenting

说明：  光谱分析中的聚类方法和判别方法,包括： 系统聚类、K均值聚类、距离判别、SIMCA法、kNN法等。(Spectroscopy clustering method and discriminant)

说明：  适用于SIFT检测缺陷，检测方法还行，可以调试调试就使用了(Template matching defect detection)

陆吾生教授的压缩感知材料，PPT格式，开始学习基础知识的同学有帮助。(Professor Lu Wusheng compressed sensing materials, PPT format.)

说明：  基于小波变换的数字水印，包含的嵌入与提取代码，原理等(Digital watermarking based on wavelet transform, including embedded and extracted code, principle, etc)

基于Matlab程序的图像细化算法基于Matlab程序的图像细化算法(Matlab program based on the image thinning algorithm based on image thinning algorithm Matlab program)

求一个图像的最大内接矩形面积。 步骤： 1.相机标定。首先根据物像关系式求出其中的参数。注意参数求出后要进行参数校验。 2.从背景中分离出目标 3.边缘检测 4.目标形状参数计算。(For an image of the largest inscribed rectangle area. Steps: 1. Camera calibration. First of all object-image relationship in accordance with the parameters obtained. Attention to the parameters obtained after parameter calibration. 2. From the context of isolated target 3. Edge detection 4. Target shape parameters.)
