采用小波变换基稀疏用正交匹配追踪算法重构的压缩传感(Sparse wavelet transform based algorithm using orthogonal matching pursuit compressed sensing reconstruction)

该程序可以进行扇形的短扫描重建，利用Parker加权函数。得到不错的重建效果。希望对大家有帮助。仅供参考！(This programme is a short-fan reconstruction.On the use of Parker weight function.I hope it will be useful.And the result of this programme is good.)

When doing optimization, GA algorithm was initially selected, but the instability of the GA (or local optimization) is really frustrating, before and after the resulting difference can at times reach more than 30 , at that time due to time reasons, I chose to optimize 1000 times, then the minimum value of the most optimal solution. Although the problems are solved, but an academic, this style of running is pretty embarrassing. So, I downloaded a GA-PSO algorithm, try using the combination of GA and PSO optimizing strategies, results algorithm issues, efficiency and good. I downloaded the original algorithm, there is a problem is that it is aimed at all upper and lower limits of the design variables are the same, so I modified the program and improvements, you can now deal with upper and lower limits of the inconsistency problem and fix the bug. Now, program modifications, and share, hoping to be useful to you

As significant work was done in machine learning in past two decades, we have limited to recent articles in machine learning. A brief review of machine learning and its application can found in [Duttion and Conroy,1996). The most common supervised learning method and major implementation to various machine learning applications is artificial neural network as ANNs.
