matlap bwselect to select object from the image you want

用MATLAB编写的读取视频图片的程序。(Using MATLAB program for reading video picture.)

本程序实现Lena图像的压缩传感，测量矩阵为哈达玛测量矩阵，重构算法采用OMP重构算法(This procedure Lena image compression sensing, measurement matrix is ​ ​ Hadamard measurement matrix, reconstruction algorithm using OMP reconstruction algorithm)

关于MATLAB的图像消噪程序，很有用的(MATLAB image denoising procedure, useful)

matlab数字信号与应用源代码6，对初学者有帮助(and application of digital signal matlab source code 6, help for beginners)

Thresholding is used to segment an image by setting all pixels whose intensity values are above a threshold to a foreground value and all the remaining pixels to a background value. Whereas the conventional thresholding operator uses a global threshold for all pixels, adaptive thresholding changes the threshold dynamically over the image. This more sophisticated version of thresholding can accommodate changing lighting conditions in the image, e.g. those occurring as a result of a strong illumination gradient or shadows.

matlab编写的调整svm参数的程序，其中cross是主程序，另两个是自己编写的svm核函数，如果要用matlab自带的核函数就把-t的值改成2即可。Ytrain是标记矩阵，Xtrain是特征矩阵，都由用户自己导入。可利用k倍交叉验证来选择最优的c参数。k可自行更改。(svm matlab prepared to adjust the parameters of the program, which cross the main program, and the other two are themselves prepared svm kernel function, if you use the value of the kernel function matlab own put-t can be changed to 2. Ytrain is labeled matrix, Xtrain is characteristic matrix, imported by the users themselves. K-fold cross-validation can be used to select the optimal c parameter. k can make changes.)
