## Dataset
**OpenSAL360** sample dataset is the largest omnidirectional video saliency dataset with the following key features:
* Large scale: **500** videos with mean **18.1s** duration;
* Fixations from **>2000** observers (**>84** per video);
* **Audio** track saved and played to observers;
* High resolution: all streams are **3840x1920**;
* Diverse content from **YouTube**;
* License: **CC-BY**;

### File Structure

1) `videos` — 500 mp4 omnidirectional videos in ERP, 30 FPS videos with audio streams;

2) `saliency` — 500 mp4 almost losslessly (crf 0, 10bit, min-max normalized) compressed continuous saliency maps videos;

3) `fixations` — 500 json files with per-frame fixation coordinates, from which saliency maps were obtained;

4) `metadata.json` — meta information about each video (e.g. license, source URL, etc.);
