  With the inclusion of camera in daily life, an automatic no reference image
quality evaluation index is required for automatic classification of images.
The present manuscripts proposes a new No Reference Regional Mutual Information
based technique for evaluating the quality of an image. We use regional mutual
information on subsets of the complete image. Proposed technique is tested on
four benchmark natural image databases, and one benchmark synthetic database. A
comparative analysis with classical and state-of-art methods indicate
superiority of the present technique for high quality images and comparable for
other images of the respective databases.
