projection operator

Analyzed the number of iteration, the threshold size, projection operator and other factors that affect the result of POCS reconstruction algorithm, and the experiments have been done.

分别对POCS重建算法中的迭代次数、阈值大小、投影算子等影响结果的因素进行分析并进行实验。

First, through the Fourier expansion, the expansion of the function u ∈ H 3 ( e) was obtained. Then, the three-dimensional interpolation operator of projection type was introduced. Finally, an equivalent construction method of this operator was given.
