CrowdFix is a dataset of 434 crowd videos with different densities, on which an eye-tracking experiment was conducted to collect human eye fixations from 26 observers. Detail of the dataset and its analysis can be found in our IEEE Access paper here. This dataset is part of the MIT/Tübingen Saliency Benchmark datasets, whose detail can be found here
Here is a demo video for an overview of the dataset:
CrowdFix includes 434 videos with diverse crowd scenes, containing a total of 37,493 frames and 1,249 seconds. The diverse content refers to different crowd activities under three distinct categories - Sparse, Dense Free Flowing and Dense Congested. All videos are at 720p resolution and 30 Hz frame rate. For monitoring the eye movements, an EyeTribe eye tracker was used in our experiment. 26 participants (10 males and 16 females), aging from 17 to 40, participated in the eye-tracking experiment. All participants were non-experts for the eye-tracking experiment, with normal/corrected-to-normal vision. During the experiment, the distance between subjects and the monitor was fixed at 60 cm. Before viewing videos, each subject was required to perform a 9-point calibration for the eye tracker. After the calibration, the subjects were asked to free-view videos displayed in an MTV style. Finally, fixations of all 32 subjects on 538 videos were collected for our eye-tracking database.
Some stills from the dataset videos are shown below:
A sample of resultant heatmaps of eye fixations over a few videos are shown below:

'CategoryInfo.xlsx' lists the information of crowd categories against each video. It includes the following information:
- 'column 1' : Video Number as given in the uploaded video folder.
- 'column 2' : Crowd Category Type (SP for Sparse, DF for Dense Free-Flowing and DC for Dense Congested)
Please have a look at this repo here, which has codes to easily add any visual saliency dataset (image/video), including CrowdFix, to evaluate any given deep learning model's performance for predicting visual saliency.
