Abstract EN
This work presents a no-reference image sharpness metric based on human blur perception for JPEG2000 compressed image.
The metric mainly uses a ringing measure.
And a blurring measure is used for compensation when the blur is so severe that ringing artifacts are concealed.
We used the anisotropic diffusion for the preliminary ringing map and refined it by considering the property of ringing structure.
The ringing detection of the proposed metric does not depend on edge detection, which is suitable for high degraded images.
The characteristics of the ringing and blurring measures are analyzed and validated theoretically and experimentally.
The performance of the proposed metric is tested and compared with that of some existing JPEG2000 sharpness metrics on three widely used databases.
The experimental results show that the proposed metric is accurate and reliable in predicting the sharpness of JPEG2000 images.
