A no-reference perceptual blur metric
We present a no-reference blur metric for images and video. The blur metric is based on the
analysis of the spread of the edges in an image. Its perceptual significance is validated …

Analyzing spatially-varying blur
A Chakrabarti, T Zickler… - 2010 IEEE Computer …, 2010 - ieeexplore.ieee.org
Blur is caused by a pixel receiving light from multiple scene points, and in many cases, such
as object motion, the induced blur varies spatially across the image plane. However, the …
