Abstract

In this paper, the relationship between Landweber iteration and the generalized inverse has been analyzed, and it is shown that Landweber iteration is, in fact, a modification of the generalized inverse that is implemented by using the iteration solution. At the same time, a new reconstruction algorithm, termed the pre-iteration method, is proposed, which splits the image reconstruction process into two steps that are the off-line pre-iteration and the on-line one-step reconstruction. The speed of image reconstruction is remarkably increased.
电阻抗层析反演问题的预迭代方法
本文分析了Landweber迭代与广义逆的关系,证明了Landweber迭代实际上是广义逆的一种修正,是利用迭代解实现的。同时,提出了一种新的图像重建算法——预迭代法,该算法将图像重建过程分为离线预迭代和在线一步重建两步。图像重建速度显著提高。
