Fecha de publicación: | 15-feb-2018 | Editor: | Elsevier | Citación: | Journal Visual Communication and Image Representation | Resumen: | The Anisotropic Quality Index (AQI) was previously introduced by the authors as a non-distortion-specific, no- reference image quality measure. AQI is based on measuring the variance of the expected entropy of a given image over a predefined set of orientations. In this paper, a statistical evaluation of AQI is provided using standard bench- marking parameters showing good match with observer’s response. Some AQI extensions are proposed for tackling ill-posed noise types that provide fair or poor performance. A comparison with other no-reference methods has been included showing good competitiveness with many of them. | Versión del editor: | https://doi.org/10.1016/j.jvcir.2018.02.008 | URI: | http://hdl.handle.net/10261/160757 | DOI: | 10.1016/j.jvcir.2018.02.008 |
