Deblurred image quality assesment

3 views (last 30 days)
Hi,
Is there any non reference quality metric for deblurred images?
ie. We have a blurred image of a real scene. We do not have its ground truth of sharp image. We deblurred it. So, is there any quantitative analysis method to find the deblurred image quality without using a reference?

A no reference quality metric for defocus deblurred images can be done based on Natural Scene statistics . We extract both global and local distortions in spatial and frequency domain . A Support Vector Regression can be used to build a model for qualitative analysis
