Ringing effect postprocessing and quality assessment method of blind restoration image
一种盲复原图像振铃效应的后处理与质量评价方法

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.
