ZK矩的计算程序，有MATLAB和C语言两部分。ZK矩在形状识别和分析中有重要应用，可以在特征参数提取中经常使用。(ZK moment calculation procedure, MATLAB and C language has two parts. ZK moments in shape recognition and analysis has important applications, feature extraction can be often used.)

this is a periodogram matlab code

This contains files which has matlab source code for room dereverberation.

Image water marking using Stationary Wavelet Transform with 3-level decomposition. The problem with DWT is lack of shift-invarience and poor spatial resolution of the resultant image. These were reduced with SWT, at the cost of memory requirements

我编写的两相机定标算法，利用matlab toolbox得到初始数据进行一步的标定和优化，其中调用了matlab toolbox里的显示函数和(I prepared two camera calibration algorithm, using matlab toolbox to obtain the initial data calibration and optimization step, which is called the matlab toolbox in the display functions and)

弹性力学中的一些基本概念，应用matlab对其进行求解，方便弹性力学初学者的学习与借鉴(Some of the basic concept of elasticity, the application of matlab them to solve the convenient elasticity beginners and learn from)

ConventionalBeamforming codes and will show us detailed information on it, including some figures

在做复合形法优化时，用到《精通MATLAB最优化设计》一书中的复合形法程序，发现做其他例题时运行不了。去掉bug后，改进如下，如果你遇到同样问题，不妨下来试试。如果你没有Funval.m，可以将程序中的Funval函数换成subs(In doing complex method optimization, use the " Mastering MATLAB Optimization Design," a book of complex method program, found other examples can not do when running. After removing the bug, improvements are as follows, if you encounter the same problem, we might try it. If you do not Funval.m, the program can be replaced by a function of Funval subs)

计算光子二维晶体米卡良透镜折射率分布的程序，同时给出米卡良透镜在径向的晶体柱半径分布(Calculated two-dimensional photonic crystal lens refractive index distribution of Mika good program, and gives good Mika crystalline lens in the radial distribution of column radius)

dct隐写技术matlab实现资料。算法原理：通过在一个图像块中调整两个DCT系数的相对大小，隐藏秘密信息。 将载体图像分为8×8的块，做二维DCT变换 用来表示选中的两个系数的坐标对于第i bit秘密信息 if（要隐藏信息‘1’） make else make 逆DCT变换，还原图像 (dct steganography matlab implementation information. Algorithm principle: an image block by adjusting the relative size of the two DCT coefficients, hidden secret information. The vector image is divided into 88 blocks, making two-dimensional DCT transform coefficients used to represent the coordinates of the selected two for the first i bit secret information if (to hide information ' 1 ' ) make else make the inverse DCT, restore image)
