一种用于射电图像重建的改进RLTV算法
Improved RLTV algorithm used to radio image reconstruction
摘要
Abstract
This article simply introduces the basic theory of total variation and the Richardson-Lucy algorithm based on Total Variation.When this algorithm is applied to radio image reconstruction,accumulated discrepancy rises gradually during the iterations as the result of the approximation in derivation;hence the recovered images are often unsatisfactory.Aiming at this problem,this article comes up with a new Richardson-Lucy algorithm based on nonlinear projection and it is successfully applied to the heliograph image reconstruction.The simulation experiment shows that it turns out to be more effective to restore the image measured by using the improved Richardson-Lucy algorithm.关键词
