Research on DR image denoising algorithm of aeroengine small diameter tube
Aiming at the problem of image blur distortion caused by the characteristics of flat panel detector in Digital Radiog-raphy(DR)imaging,the image denoising research was carried out with the detection image of aeroengine small-diameter tube DR as the experimental object,and the fuzzy model was established and iterated by Lucy-Richardson algorithm.The experimental re-sults show that the image recovery quality is better when the iteration times of the algorithm is 31 and the parameters such as struc-tural similarity and information entropy are taken as objective evaluation indexes.Compared with traditional denoising algorithms such as Wiener filter,the algorithm is suitable for DR image denoising.
