这是一个MATLAB工具箱包括32个降维程序，主要包括 pca,lda,MDS等十几个程序包，对于图像处理非常具有参考价值！！( ，This Matlab toolbox implements 32 techniques for dimensionality reduction. These techniques are all available through the COMPUTE_MAPPING function or trhough the GUI. The following techniques are available: - Principal Component Analysis ( PCA ) - Linear Discriminant Analysis ( LDA ) - Multidimensional scaling ( MDS ) - Probabilistic PCA ( ProbPCA ) - Factor analysis ( FactorAnalysis ) - Sammon mapping ( Sammon ) - Isomap ( Isomap ) - Landmark Isomap ( LandmarkIsomap ) - Locally Linear Embedding ( LLE ) - Laplacian Eigenmaps ( Laplacian ) - Hessian LLE ( HessianLLE ) - Local Tangent Space Alignment ( LTSA ) - Diffusion maps ( DiffusionMaps ) - Kernel PCA ( KernelPCA ) - Generalized Discriminant Analysis ( KernelLDA ) )

二维码扶正,对不同光照图片都有较好结果，涉及几种不同的二值化方法，采用霍夫检测直线和双线性变换扶正二维码，内含的7张图片都能扶正(Two-dimensional code righting, have a better picture of the different light result, involving several different binarization method using Hough transform to detect linear and bilinear righting two-dimensional code, embedded image 7 can be righting)

图像SURF特征提取，用于图像拼接和篡改检测，注释比较详细，程序很好理解(SURF feature extraction, image is used for image matching and tamper detection, comments are detailed, the program is easy to understand)

基于形状的灰度共生矩阵的图像检索，利用基元扫描图像(Shape-based image retrieval GLCM, using primitive scanned image)

用扩散滤波实现图像增强，包括高斯滤波预处理，梯度计算，结构张量计算，扩散张量计算，数值离散以及增强效果评估代码(Diffusion-image enhencement)

在matlab环境下对图像进行处理，运用霍夫变换方法得到图像分割的阈值，并进行圆形的检测(In the matlab environment for image processing, using Hough transform method for image segmentation threshold and for the detection of circular)

图像基础处理——透视矫正的程序代码，把图像还原(Image basic processing- perspective correction code to restore image)

C#调用DLL实现图像文字识别(OCR)(C # call DLL realize image character recognition (OCR))

opencv安装指导文件，针对vs2010版本和opencv2.2版本(opencv installation guidance document for vs2010 version, and opencv2.2 version)

说明：  采用积分图算法的归一化互相关匹配，大大减少了计算时间。(Normalized cross correlation matching)
