变分不等式求解算法之一，投影算法是将变分不等式的解进行投影，然后进行迭代。(One of the variational inequality solution algorithm, the projection method for variational inequality solution to the projection, and then iterate)

matlab解决多参数优化问题，已经调通过，可以直接使用。并且目标函数有微分构成。(matlab to solve the multi-parameter optimization problems, have been transferred through, can be used directly. And the objective function differential constitute.)

SLEP稀疏学习算法工具，对图像进行降噪处理，有明显效果(SLEP sparse learning algorithm tool for image noise reduction, a significant effect)

增广最小二乘的递推算法对应的噪声模型为滑动平均噪声，扩充了参数向量和数据向量H（k）的维数，把噪声模型的辨识同时考虑进去。最小二乘法只能获得过程模型的参数估计，而增广最小二乘法同时又能获得噪声模型的参数估计，若噪声模型为平均滑动模型，，则只能用RELS算法才能获得无偏估计。当数据长度较大时，辨识精度低于极大似然法。(Augmented least squares of recursion algorithm corresponding noise model for moving average noise, expanded parameter vector and data vector H (k) of the dimension, the noise model identification and at the same time into consideration. Least square method can only obtain process model parameter estimation, and augmented least squares method at the same time can obtain noise model parameter estimation, if noise model for the average sliding model,, it can only use RELS algorithm to obtain unbiased estimation. When the data length is bigger, the identification accuracy is lower than maximum likelihood method.)

本文是编程来实现中值滤波，从而达到图像去噪的目的(This is a program to achieve the median filter, so as to achieve the purpose of image denoising)

基于压缩传感的匹配追踪重建算法研究。给出了OMP的一种改进方案。OMP算法本身耗时过长速度过慢，本文的改 进方案将图像进行分块后再处理，从而大大降低了OMP算法每次迭代的矩阵规模。 实验结果表明，该方案在不明显降低重建效果的同时提高了运算速度。(Matching track reconstruction algorithm based on compressed sensing)
