代码说明：

压缩感知CS——采用小波变换进行稀疏表示，高斯随机矩阵为观测矩阵，重构算法为OMP算法，对256*256的lena图处理，比较原图和OMP算法在不同采样比例(0.74、0.5、0.3)下的重构效果，并各运行50次，比较算法性能PSNR和每次的运行时间 (Compressed sensing CS- using wavelet transform as sparse representation, Gaussian random matrix as the observation matrix and OMP algorithm as the reconstruction algorithm. Compare lena figure and the reconstruction results using OMP algorithm at different sampling ratio (0.74,0.50.3),then each runs 50 times, compare the performance of PSNR and each running time)

幻方的构造及幻方实现的程序，对于其他双偶阶的幻方，只是在作‘*’标记时，应把4N阶方阵分为N个4阶方阵进行标记，数字填入仍按从左到右，自上而下填入(Magic Square and the magic square implementation procedures for other pairs of even order magic square, just as ' *' mark should be put into N 4N square matrix of order 4 squares labeled, digital still fill left to right, top to bottom fill)

ImproveCanny
一个改进的自适应canny算法，该方法采用改进的开关型中值滤波器对图像做去噪工作，再把整幅图像分割为若干子图像，最后在充分考虑全局以及各子图像的边缘梯度信息后，自适应地生成动态阈值。(The new Canny adaptive method divides image into sub-images,then determinates the thresholds automatically according to the whole image edge information and the sub-images edge information.)
