特征提取，主要是灰度共生矩阵和不变矩特征提取的程序，openCV下可直接运行(Feature extraction, mainly GLCM and invariant moments feature extraction procedures can be run directly under openCV)

对全息图进行卷积法的再现，利用matlab计算全息图模拟仿真(Reappearance of convolution method for hologram)

小波基的构造，每步均有说明，讲解很详细，值得学习(Wavelet construction, each step that has to explain in great detail, it is worth learning)

数学形态学去噪 有效地还原了原始信号 去除了振动噪声和基线漂移(signal denoising )

基于小波变换以及快速傅立叶变换的时频分析程序，很实用(cwt fft)

说明：  python实现人脸识别，通过pca进行降维然后使用SVM算法进行分类(Python realizes face recognition, dimensionality reduction through pca and classification by SVM algorithm)

说明：  该算法实现了数字水印的嵌入与提取，然后对图像进行均衡化处理，分析均衡化处理后的图像对数字水印嵌入和提取效果的影响。(The algorithm realizes the embedding and extraction of digital watermark, and then carries on the equalization processing to the image, analyzes the influence of the equalization processed image on the embedding and extraction effect of digital watermark.)

说明：  虚拟内窥镜关键技术研究 虚拟内窥镜技术（Virtual Endoscopy）是虚拟现实技术在现代医学中 的应用。它利用医学影像作为原始数据，融合图像处理、计算机图形学、科 学计算可视化、虚拟现实技术，模拟传统光学内窥镜的一种技术。它克服了 传统光学内窥镜需把内窥镜体插入人体内的缺点，是一种完全无接触式的检 查方法。虚拟内窥镜的研究旨在为医生提供诊断依据，还可应用于辅助诊断、 手术规划、实现手术的精确定位和医务人员的培训等。(Research on key technologies of virtual endoscopy virtual endoscopy (Virtual Endoscopy) is a virtual reality technology in modern medicine. It has made use of medical imaging as an original data, the integration of image processing, computer graphics, scientific visualization, virtual reality technology to simulate a conventional optical endoscope technology. It overcomes the traditional optical endoscope to be inserted into the endoscope body of the shortcomings of the human body is a no-contact inspection method. Virtual Endoscopy of the study was to provide diagnosis for doctors, but also applies to diagnosis, surgical planning, to achieve precise positioning of surgical and medical personnel training.)

DLT标定算法的matlab程序，对学习标定的人有用(DLT algorithm matlab calibration procedures)

nca,近邻成分分析，距离度量学习里常用的。(nca)
