Linear space-invariant image restoration algorithms often introduce ringing artifacts near sharp intensity transitions. It is shown that these artifacts are attributable to the noise

the different of the restoration parameters and the restoration algorithms. This paper presents a blind deconvolution image ringing metric. According to different ringing artifact types

two ringing metrics are presented to measure the ringing artifacts in restoration images by using Gabor filter and Co-occurrence vector etc. Finally

a whole ringing metric is proposed. The experimental results validate the proposed method perform well over a wide range of restoration image ringing levels and restoration algorithms. And the proposed model is in good agreement with MOS.
