The MIT300 dataset contains 300 natural images. Since the official data of eye tracking of 39 observers for each image has not been released, this dataset can only be used as a test dataset and cannot be used to train models. Users can develop eye tracking models and use this dataset as a test set. Send an email to saliency@mit.edu to get official feedback.
