Objective image quality evaluation model for JPEG2000 coded images based on edge information measures

摘要

In this paper, a no-reference objective quality assessment model is proposed for JPEG2000 coded images. It is well established that human visual system is very sensitive to edge information; consequently we believe that perceptual artifacts of any image are strongly dependent on local features such as edge and non-edge areas. Therefore edge and non-edge area based distortions are evaluated in this model. Performance of the model is evaluated by using the subjective experiment results of the LIVE Texas's database. The performance is also compared with other existing methods and the result is inevitably sufficient.
