Abstract

Abstract

In order to meet the requirement of symmetry tuning and measurement in implosion experiment, a image processing method has been adopted. This method is based on Legendre fitting, with the theory of radiation drive symmetry，which help the analysis of compressed core image. Through a series of data analysis, a detailed comparison of two methods has been processed. The results show the error of the new method is smaller than that of the current applied image processing method, and the new methodcan get more high modes details (neglected in the past).
