Database Description

Eye-tracking data was collected in order to better understand how people look to images when assessing image quality. In the experiment, people were shown images and were given two different tasks. One was to simply look at the images as if they were looking at a photo album. The other was to assess the quality level of the images. With the eye tracker it was possible to track the eye movement of the viewers and map the salient regions for images given different tasks and with different levels of image quality.
More details on the experimental set-up and results can be found in the references given above.
