Description

ABSTRACT:

we propose a new intraand- inter-constraint-based video enhancement approach aiming to: 1) achieve high

intraframe quality of the entire picture where multiple regions-of-interest (ROIs) can be adaptively and 

simultaneously enhanced, and 2) guarantee the interframe quality

consistencies among video frames. We first analyze features from different ROIs and create a piecewise tone

mapping curve for the entire frame such that the intraframe quality can be enhanced. We further introduce new

interframe constraints to improve the temporal quality consistency.
