旋转图像回归，图像拍照时有角度，此程序是将图像置平。(Rotating image regression )

说明：  二维码识别，matlab代码，内附二维码，内有界面，选择输入，注意输入顺序！(Two dimensional code identification, matlab code, two-dimensional code inside, interface inside, select input, pay attention to the input sequence!)

说明：  一种新的图像清晰度评价函数,该函数对经典采用八方向模板Sobel边缘检测算子来检测梯度值(A new image definition evaluation function, which uses eight direction template Sobel edge detection operator to detect gradient value)

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)

基于matlab的RANSAC算法，主要用来拟合二维直线，同时选出非直线的点用于后续曲线拟合。(The RANSAC algorithm based on MATLAB is used to fit two dimensional lines, and the point of non straight line is selected for the subsequent curve fitting.)

西安科技大学，图像处理教程的课件，做成了PDF格式，希望对你们有用(Xi' an University of Technology, image processing tutorial courseware, made the PDF format, hope that is helpful for you)

在Matlab中建了图形用户界面，采用不同特征提取方式，如gray，color，lbp，灰度共生矩阵GLCM等，对数据集中的影像进行场景检索。(Graphic user interface is built in Matlab. Scene retrieval of images in dataset is carried out by using different feature extraction methods, such as gray, color, lbp, gray level co-occurrence matrix (GLCM).)

说明：  本文为图像分割源代码，把一幅在MATLAB中读入的图像分割成任意块(This article image segmentation source code, put a read into the MATLAB image is divided into arbitrary blocks)

提取目标各种特征，图像处理，目标几何特征，纹理特征等(Extract various features, image processing, target geometric features, texture features, etc.)

PCA+SVM，对图像进行降维分类，并在yale库上测试取得比较好的效果(PCA+ SVM, dimensionality reduction of image classification, and yale library to achieve better test results)
