Fragile-watermarking-based-on-DWT

基于马尔可夫随机场的图像恢复，给出产生MRF的程序并应用于图像去噪(GMRF based on the image restoration, MRF is generated and applied to the procedures Image Denoising)

实现不规则形状碎纸片的拼接，并展示出原图像(The splicing of irregular shaped pieces of paper is realized and the original image is displayed.)

进行纯净信号和加噪信号的时频域显示，及其包络图显示，并计算加噪信号的信噪比、互相关系数、峭度值，对信号进行离散余弦变换。(The time-frequency domain display of pure signal and noise-added signal and its envelope diagram display are carried out, and the signal-to-noise ratio, correlation coefficient and kurtosis value of noise-added signal are calculated.Making Discrete CoSine transform for signal)

说明：  图象压缩方面的论文 可用于毕业设计方面的工作(Image compression can be used for graduate thesis work of design)

说明：  很好用的三维重建软件，VisualSFM软件允许上传一系列图像，它从这些图像中找到每一个图像的特定特征，利用这些特征信息重建出3D模型的稀疏点云，而后还可进行稠密点云重建。(The VisualSFM software, a good 3D reconstruction software, allows uploading a series of images. It finds the specific features of each image from these images, and USES these feature information to reconstruct the sparse point cloud of the 3D model, and then it can reconstruct the dense point cloud.)

对比两张图片上的散斑的变化来确定被测材料的变形和相关位移(Change of speckle contrast two images to determine the detected material deformation and displacement)

自己编的nsct和pcnn结合的融合程序,简单易懂，pcnn采用的不是改进型的，传上来供大家参考，运算复杂，出结果很慢。(A fusion algorithm based on NSCT-PCNN.It is easy to understand,but the quantity of arithmetic is large, and it costs a long time.)

截断核范数程序，admm和apg的实现过程(Truncation of kernel norm programs, the implementation of ADMM and APG)

说明：  包括几种基于多项式插值的图像处理matlab代码，包括双三次插值，样条差值等(Includes several image processing based on polynomial interpolation matlab code, including double-cubic interpolation, spline difference, etc.)

说明：  MATLAB实现的图像处理算法,计算图像中的欧拉数,(MATLAB realize the image processing algorithm to calculate the Euler number of images,)
