自己编写的字幕提取代码，matlab简单易用(Caption extraction)

一款完全免费的专业级屏幕捕捉软件，能够让您得心应手地捕捉到需要的屏幕截图。捕捉图像方式灵活，主要可以捕捉整个屏幕、活动窗口、选定区域、固定区域、选定控件、选定菜单、选定网页等，图像输出方式多样，主要包括文件、剪贴板、画图和打印机。软件具有捕捉光标、设置捕捉前延时、显示屏幕放大镜、自定义捕捉热键、图像文件自动按时间或模板命名、捕捉成功声音提示、重复最后捕捉、预览捕捉图片、图像打印、图像裁切、图像去色、图像反色、图像翻转、图像旋转、图像大小设置、常用图片编辑、墙纸设置等功能。捕捉到的图像能够以保存图像文件、复制到剪贴板、输出到画图、打印到打印机等多种方式输出。 (A completely free professional screen capture software that allows you to be able to adequately capture the need for a screenshot. A flexible way to capture the image, the main can capture the entire screen, active window, selected regions, fixed region, the selected control, the selected menu, select Web pages, images, various output methods, mainly including documents, clipboard, drawing and printers. Software has to capture the cursor, set the delay before the capture, display screen magnifier, custom capture hotkeys, image file names automatically by time or templates to capture the success of the voice prompts, repeat last capture, preview captured pictures, image print, image cut , the image to the color, the anti-color images, image flip, image rotation, image size setting, commonly used photo editing, wallpaper settings and other functions. Images can be captured to save the image file, copy to the clipboard, export to the drawing, print to a printer output of a variety of ways)

基于DCT的jsteg图像隐写及分析算法，MATLAB实现。 JSteg的算法主要思想是将秘密消息嵌入在量化后的DCT系数的最低比特位上，但对原始值为O、1的DCT系数不进行嵌入。提取秘密消息时，只需将载密图像中不等于0、l的量化DcT系数的LSB取出即可。(The main idea of the JSteg algorithm is to embed secret messages in the lowest bit of the quantized DCT coefficients, but the DCT coefficients of the original values are O and 1 are not embedded. When extracting secret messages, only the LSB of the quantized DCT coefficients not equal to 0 and l in the encrypted image can be taken out.)

图像分割，双峰法.显示直方图，根据直方图确定阈值，并根据次阈值进行图像的风格(segmation)

基于仿射变换的图像匹配程序，这是基于mablab的一个主程序(Affine transformation based on the image matching process, which is based on a main mablab)

图像处理领域有很多滤波器，好的滤波器可以很快的提取有效的特征，MR8是一组特别好的滤波器组，比gabor filter更好，这里是MR8的源码，有需要的可以下载一用！(There are a lot of image processing filter, a good filter can quickly extract effective feature, MR8 is a particularly good filter group, better than gabor filter, here is MR8 source, there is a need to download a use!)

数字图像抠图源代码,是由一个外国人写的，非常好用，我希望能和大家一起分享(digital image matting matlab code written by a foreigner,it is very useful and I would like to share with everyone)

中值滤波是一种非线性数字滤波器技术，经常用于去除图像或者其它信号中的噪声

说明：  图像处理的位图操作，256色转为灰度图，图像处理入门源程序(Bitmap image processing operations, 256-color to grayscale, image processing, entry-source)

载入一副图像并进行平滑处理与高斯或其他核函数进行卷积有效的减少图像信息内容(Loading an image and smoothed with a Gaussian or other nuclear convolution function effectively reduce the information content of the image)
