说明：  Image Watermarking. It is used to water mark digital images using asymmetric method

说明：  Matlab,图像识别，计算图像中物体的个数。测试图片读入图像程序图像识别计数主程序 (objectrecog)

说明：  例题运行步骤:在Matlab命令窗口将本章目录置于当前目录；在Matlab命令窗口的当前目录中打开本章目录中的M文件Exam.m；在Exam.m文件中，将待运行例题前的注释符号“ ”去掉，并保留其他例题前的注释符号“ ”；在命令窗口键入：Exam 并回车即可运行该例题。(Example run these steps: In the Matlab command window will be placed in this chapter directory the current directory in the Matlab command window to open the current directory in the directory of this chapter M files Exam.m in Exam.m file, will be run before the note symbol example &quot &quot removed and reserved comment symbol in front of the other examples, &quot &quot in the command window, type: Exam and press Enter to run the examples.)
