中值滤波：采用5*5窗口对噪声污染的图像进行去噪处理。(Median filter: 5* 5 window on the noise pollution to deal with the image de-noising.)

维纳滤波对图像模糊的处理以及对加入噪声的图像进行清晰处理(Wiener filter for image processing and fuzzy image on a clear noise added deal)

角点检测程序，能够标记出图像中的角点。角点检测是图像匹配对第一步(corner detection procedures can mark up images of the corner. Corner detection is the first step in image matching)

说明：  该算法主要包含PCA算法和K-Means聚类算法，用于SAR变化检测,包含数据图片。(The algorithm mainly includes PCA algorithm and K-means clustering algorithm for SAR change detection, including data images.)

用六种算子(分别是gabor、拉普拉斯、priwitt、robert、sobel、wallis),对三种图象进行边缘检测比较，强烈推荐哦，是本人的毕业设计中的关键程序(The six operators (respectively gabor, Laplace, priwitt, robert, sobel, wallis), images of three edge detection comparison, strongly recommend Oh, my graduation project is a key process)

very useful toolbox for the matlab user

通过求差分曲线，利用阈值分割算法对图像进行自动多阈值分割(image segment method)

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 ) )

图像分割，显著性算法的precision，recall 和ROC的评价指标计算。(Image Segmentation, significant precision,recall and ROC assessment index calculation algorithm.)

说明：  简单的介绍了基于matlab的QR码的识别，包括图像的预处理，图像定位，图像的识别等(This paper briefly introduces the recognition of QR code based on matlab, including image preprocessing, image positioning, image recognition and so on.)
