Task impact on the visual attention in subjective image quality assessment
Résumé
Visual attention is a main feature of the Human Visual System (HVS). Knowing and using the mechanisms of the visual attention could help to the improvement of image quality assessment methods. But, which kind of saliency should be taken into account? A free-task visual selective attention or a quality oriented visual selective attention. We recorded and evaluated the discrepancy between these two types of oculomotor behavior. The results show the impact of the viewing task on visual strategy.
