simple function to test watermarking

利用matlab GUI设计一款图像处理软件，大作业成果，包括对图像预处理，以及融合(use matlab disgin a matlab gui in order to process image)

此源码主要功能是在图像分析时将8连接边界转换为4连接边界，在图像分割、描述和识别中有较大的用途(The main function of this source is in the image analysis will be 8 to connect the border converted to 4 to connect the border, in the image segmentation, description and identification of a greater use of)

利用MATLAB实现正交滤波器组的设计。(Use MATLAB to achieve the design of orthogonal filter banks.)

利用Matlab工具对巴特沃斯模拟低通滤波器的设计结果进行了验证，Matlab程序见附页。(Matlab simulation tools Butterworth low-pass filter design results were verified, Matlab program Annex.)

概率统计 matlab求解 参数估计 假设检验 方差分析等(Probability and Statistics matlab to solve the parameter estimation and hypothesis testing analysis of variance)

对每一路图像进行小波变换，分别到其水平、垂直、四十五度角方向的高频分量以及其低频分量，得到每路图像的小波金字塔； 按取较大值的原则对两幅图像的不同层次、不同特征层的信息图分别进行融合； 根据融合的各图像分量的小波序列，进行小波逆变换，得到最后的融合图像。 (Road images of each wavelet transform, respectively, to its horizontal, vertical, 45 degree angle the direction of high-frequency components as well as its low-frequency components obtained for each road image wavelet pyramid according to the principles of taking a larger value of the two images different levels of information mapping feature level fusion respectively the basis of integration of various components of the wavelet image sequences, inverse wavelet transform, to be the final fusion image.)

循 环 相 关 谱检 测 法 的 检 测性 能 优 于循环 相 关 谱 系 数 检 测法,但 循环 相 关 谱检 测法 的 性 能 受 噪 声 功 率 估 计 误 差 影 响 大,而 循环 相 关 谱 系 数 检 测 法 不 需 要 已 知 噪 声 功 率,实 用性 更 强(Circular correlation spectrum inspection measurement method of inspection measurement can be optimal in cyclic correlation spectrum coefficient measuring method, but closed loop phase spectrum detection method of measuring performance is affected by the noise power estimation error is large, and cyclic correlation spectrum coefficient test don t need to noise power ratio is known, use sex is stronger)

本程序运用bing yang的PAST算法和PASTD算法跟踪信号子空间，并利用MUSIC算法估计信号的波达方向(DOA)(This procedure utilizes the PAST algorithm and the PASTD algorithm (put forward by Bing Yang)track signal subspace, and uses MUSIC algorithm to estimate signal prameter Direction Of Arrival(DOA) )

图论研究中的独立集问题的matlab程序，实践证明很好用啊！(Graph Theory Research the issue of an independent set of matlab procedures, practice has proved very good with ah!)
