摄像头录制功能

在此文档中，可以实现图形字母的识别，采用特征匹配的 方法，求取特征向量，一共13个(ocr)

说明：  实现了监控视频图像的去隔行算法，使隔行扫描的图像插值成为逐行扫描(The realization of the surveillance video images Deinterlacing Algorithm, so deinterlacing Image Interpolation become progressive scan)

You can generate image with colored bars and u can analise signals of image

迭代阈值方法进行图象分割的函数,有测试程序和图片(threshold iterative method of image segmentation function, test procedures and Photo)

说明：  程序代码说明 P0401：用Prewitt算子检测图像的边缘 P0402：用不同σ值的LoG算子检测图像的边缘 P0403：用Canny算子检测图像的边缘 P0404：图像的阈值分割 P0405：用水线阈值法分割图像 P0406：对矩阵进行四叉树分解 P0407：将图像分为文字和非文字的两个类别 P0408：形态学梯度检测二值图像的边缘 P0409：形态学实例——从PCB图像中删除所有电流线，仅保留芯片对象 (some imageprocessing sourcecode)

说明：  用于粒子图像测速技术的图像处理，分析得到流场信息(Image Processing for Particle Image Velocimetry and Flow Field Information Analysis)

可以设置图像分块的大小和分块数，然后来分块保存图像到文件目录下面(You can set the size of the image sub-block and sub-blocks, and then to block to save the image to a file directory)

说明：  注：运行前自己准备图像，修改I = imread('')单引号中的路径 1. 给一张灰度图添分别添加高斯噪声和椒盐噪声。然后分别进行均值滤波和中值滤波，并把处理后的图片保存。 2. 图像频域处理，对图像进行傅里叶变换，进行高通滤波，显示处理结果。 3. 图像平移和旋转 4. 分别用OSTU阈值法和全局阈值法分割图像，然后进行腐蚀和膨胀处理，显示处理结果。(Note: Prepare the image by yourself before running, modify the path in single quotes of I = imread('')1. Add Gaussian noise and salt and pepper noise to a grayscale image. Then perform mean filtering and median filtering respectively, and save the processed pictures.2. Image frequency domain processing, Fourier transform of the image, high-pass filter, and display the processing result.3. Image translation and rotation4. Separate the image with OSTU threshold method and global threshold method, and then perform corrosion and dilation processing, and display the processing results.)

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.)
