This repository contains an API for saliency prediction datasets along with most common evaluation metrics. This code will download required files from the website of the original publisher of datasets.
- Python (2.7, 3.4+)
- Python package manager (pip)
- Matlab (optional - required for some of the metrics.)
-
Clone the repository using the following command:
`git clone git@github.com:rAm1n/saliency.git`or download a zip version from master.zip
-
Install required packages using pip
pip install -r requirements -
Follow the tutorial: help.ipynb
At this moment, the following datasets are covered. I have plan to add more and complete this list. Some of them have other very useful annotations but given the variety of types, I have decided to not include external information at this point.

Note: To make things run smoother, scanpaths has already been preprocessed and stored on dropbox. If you own one of the datasets and you don't like your data to be included in this package, please send a short message to fahimi72 At gmail and it will be taken care of. we do not own any of the data and the rights belong to the original publisher of the datasets. Please make sure to cite the appropriate paper if you are using them.
