一个快速而精确的一阶稀疏图像复原算法。主要应用于图像去噪声。(A fast and accurate first-order sparse image restoration algorithm. Is mainly used in the image to the noise.)

说明：  为了达到较好的隐藏效果，本文采用游程编码的方法在二值图像中隐藏信息。秘密信息嵌入时修改二值图像的游程长度，如果秘密信息为是0，则修改该游程长度为偶数；如果秘密信息的取值与游程长度的奇偶性相匹配，则不改变游程长度。提取时根据游程长度奇偶性提取出秘密信息。在信息隐藏时，改变游程的奇偶性时通过对下一个游程的第一个像素值进行修改，因此当下一个游程长度为1时通过改变当前有成的值实现。(In order to achieve better hiding effect, we use run length encoding method to hide information in two value images. When the secret information is embedded, the length of the travel length of the two value image is modified. If the secret information is 0, the length of the travel length is even even. If the value of the secret information is matched with the parity of the length of the run, the length of the journey is not changed. The secret information is extracted according to the parity of run length. In information hiding, changing the parity of the journey is modified by the first pixel value of the next run, so the current length is 1 by changing the current value.)

自己做的3-PSS并联机器人可达工作空间绘制的MATLAB程序， workspace_main.m为主程序，在MATLAB中进入解压缩后的文件夹并运行workspace_main即可完成绘图。 另外Trirspace.m为3-RRR平面并联机器人可达工作空间的绘图程序，调用方法相同。(The 3-PSS parallel robot designed by myself can reach the MATLAB program drawn in workspace. The workspace_main.m is the main program. The drawing can be completed by entering the decompressed folder in MATLAB and running workspace_main. In addition, the drawing program of 3-RRR planar parallel robot reachable workspace is called by the same method.)

保铮院士的《雷达成像技术》一书，对雷达成像原理等方面做了较详的介绍，对学习微波方面的有借鉴。(Bao Zheng academician of the radar imaging technology, a book on the radar imaging principle, etc. have done a more detailed description of the study area are from the microwave.)

说明：  HU的七个不变矩，每个文件是一个子程序，对应冈萨雷斯的数字图像处理教程的(HU)

在图像中加入某个分数值（int），然后检测这个分数，要求在图像受到攻击时能有效（100％）提取这个值(In the image by adding a Score value (int), then detection of the scores, the requirements in the image can be attacked effectively (100) extraction of this value)

基于分数阶微分的图像增强技术，代码可以根据图像的梯度信息，更好地增强图像的高频部分，非线性地保留低频部分。(Fractional differential enhancement technology-based image code according to the gradient information of the image can better enhance the high frequency part of the image, to retain the low-frequency part of the non-linear.)
