Face detection Face detection (Face detection)

典型的LSB水印嵌入和提取算法，它是一个基本的matlab程序，可以帮助初学者入门 (typical LSB embedding and extraction algorithm, which is a basic Matlab procedures, Portal can help beginners)

说明：  特效显示，交叉飞入等。。。来自VC++图像处理程序设计配套光盘(Effects show that such cross-fly. . . From the VC++ image processing program design supporting CD-ROM)

运用本征模式匹配理论研究了声子晶体实际的声学速度沿两个高度对称的方向上的第一布里渊区里的特性。(The effective acoustic velocity along two highly symmetric directions of the first Brillouin zone is studied in a two-dimensional squarely arranged solid-solid phononic crystal.)

计算二维图像的分形维数,将彩色图像灰度处理，然后转换成二值图 进行分形维数计算(calculate the fracture dimensions of the picture)

基于小波变换以及快速傅立叶变换的时频分析程序，很实用(cwt fft)

将保存有灰度图像信息的txt文件转化生成灰度图片。 txt数据只能包含数据，数据用逗号或者空格隔开，所存数据个数应与所生成的图片大小相同。例：要还原的图片大小为640*480，那么txt文件中就应当有307200个数据。(The txt file with information of grayscale image is transformed into gray image. The TXT data can only contain data, separated by commas or spaces, and the number of data stored should be the same as the size of the generated image. Example: the size of the image to restore is 640*480, so there should be 307200 data in the txt file.)

通过在matlab软件平台上进行仿真，实现天线阵列的自适应波束赋形(Realization of adaptive beamforming)

求s=a+aa+aaa+aaaa+aa...a的值，求最大公约数和最小公倍数(Seeking s = a+aa+aaa+aaaa+aa ... a value, find the greatest common divisor and least common multiple)

说明：  对文字识别并计算7个不变矩的matlab源程序(right words to identify and calculate seven unchanged Moments Matlab source)
