*DESCRIPTION*

-----------

We present a dataset of human visual attention on 2D images during scene free viewing. This dataset includes 1900 images, which are corrputed by various image transformations. This dataset is manually annotated with human eye-movement data recorded by Tobii X120 eye-tracker. This dataset provides a new benchmark to measure the robustness of saliency prediction models on various transformed scenes.
