计算SENSE重建图像中的g-factor,这是并行磁共振成像SENSE算法的关键一步(G-factor is the metric to quantify the amplificaiton of noise power in reconstructing SENSE accelerated image. The detail was presented in Pruessmann s 1999 Magn. Reson. Med. paper. In theory, g-factor is the pixel-by-pixel ratio of the image variance between the SENSE reconstructed image and un-accelerated image. And g-factor depends on: (1) the k-space data trajectory (2) coil sensitivit profiles (3) noise covariance matrix of the array coil)

该Matlab程序给出了Schmidt-Kalman filter和标准Kalman filter之间的性能对比，不是函数的形式，是直接的可执行程序，如有需要，直接更改文件中的参数就可以了(The Matlab program gives the Schmidt-Kalman filter and standards of performance comparison between the Kalman filter is not a function of the form is directly executable program, if necessary, change the file directly to the parameters can be a)

地震剖面图的显示程序，使用matlab编写 ！(Seismic profile display program, the use of matlab !)

matlab读取dbf格式文件，使用成功可以。(matlab read dbf format file)

计算视频图像中每一帧的能量,matlab 代码，可以用于分析图像原能量与编码解码后，误差与原图像能量的倍数关系(computing the energy of each frame in image processing)

这个算法是matlab里面压缩感知OMP算法的程序，对一个信号进行采样。(This algorithm is inside compressed sensing OMP algorithm matlab program, a signal is sampled.)

绘图并还有指定的legends and colorbars(his function will create a new figure containing the axes/uipanels specified, and also their associated legends and colorbars. )

MPSK调制体制在黑障信道下的MATLAB/Simulink仿真(MPSK modulator simulate in blackout using MATLAB/Simulink)

说明：  对二维图像去噪，使用分数阶傅里叶变换算法。(For two-dimensional image denoising, fractional Fourier transform algorithm is used.)
