摘要
由于图像盲复原过程中先验信息的不足,往往造成复原图像质量不尽如人意,振铃效应就是影响复原图像质量的重要因素之一。振铃效应的存在使得对复原图像的后续处理难于进行,并使得一些图像质量的评价方法失效。针对图像盲复原的特点,提出了一种振铃效应的后处理方法,并基于将振铃与清晰度分别评价的思想,提出了一种复原图像的无参考评价方案。实验证明该去振铃方法简单有效,该复原图像的评价方案也很好地反映了人类的视觉特性。
Because of the shortage of prior information in the blind restoration processing, the result of restoration is usually not satisfactory. Ringing effect is one of the important factors that influence restoration image quality. It is difficult to do the postprocessing and the quality assessment of restoration image because of the ringing effect. Taking the characteristics of blind restoration into account, a ringing effect postprocessing method was proposed. And according to the thought of assessing ringing effect and definition respectively, a non-reference assessment project of restoration image was put forward. Experimental results prove that the ringing postprocessing method is simple and valid, and the assessment project of restoration image reflects human vision characteristics nicely.
