图像重建迭代算法的研究

对于图像重建中的代数迭代算法而言,松弛因子的选择会影响图像重建的质量。经典算法一般采用常数形式的松弛因子进行重建,给出一种动态选择松弛因子的方法。实验结果表明,使用该方法进行图像重建时,有较好的边界效果。

In image reconstruction, the choice of flabby coefficient of ART will influence the reconstruction quality. The traditional algorithms use constant flabby coefficient. In this paper, dynamic flabby coefficient was introduced. The result expresses that dynamic flabby coefficient iterative algorithm can reconstruct the boundary more clearly.
