ground_truthscontains the self-reported ground-truths for affect and cognitive load.infocontains additional meta data, e.g., train-val split, pre-study responses, etc. Please find details below.videos/per_participant_per_taskcontains full length videos of each participant per each task. Video length of 2.5-10 minutes, resolution of 640x360 pixel, format.mp4.videos/shorter_segmentscontains segmented clips of the same videos inper_participant_per_task. Video length approximately 6 seconds, resized the shorter side at 256 pixel, format.avi. Note, the shorter clips are prepared for easy and efficient to use to train deep learning models.face_crops/shorter_segments_facecontains the face crops of the participants. To train the baseline models we use just the face-crops instead of the full frames, which works better (at-least for simple models).
Step 1: To access this dataset you must have an account in the Dataverse using an institutional email address. Please go to this link to create an account: https://borealisdata.ca/loginpage.xhtml.
Step 2:
Once you have an account, and signed in on the same browser simply click on this link https://borealisdata.ca/dataverseuser.xhtml?selectTab=apiTokenTab, it will show the your API Token. Alternatively, you can click on the drop down list shown under your name (top right corner), and click API Token. Please note the API Token which will be required at future step.
Step 3:
Once the account is created please go to this link https://borealisdata.ca/dataset.xhtml?persistentId=doi:10.5683/SP3/PSWY62. Select all 1,918 59960 files in this dataset and Request Access. Please read the Terms of Use and Terms of Access and Accecpt to submit a request. Please see the screenshot below. This screenshot was taken before the face crops are uploaded. Now, the number of total files and size are changed.
Step 4: Your request to access this dataset is successfully submitted. It may take 5-7 days to approve the request, if your access is not granted by that time, please write us an email at [email protected] and/or [email protected]. Once your request is approved please proceed to the next step.
Step 1:
We provide a script to download the dataset. Create a directory where you want to download the dataset and go to that directory. Please run the following commands from a terminal mkdir avcaffe and cd avcaffe.
Step 2: Please run the following command to clone the github repository in your current location.
git clone https://github.com/pritamqu/AVCAffe.git
cd AVCAffe
Step 3:
Please open the codes/downloader/downloader.py using a text editor. Please update the API_TOKEN variable with your API Token noted earlier.
Step 4: Next, please ensure you have the required packages installed or you can install them by running
pip install -r codes/downloader/requirements.txt
Step 5: You can download the entire dataset simply running the following command:
python codes/downloader/downloader.py
Step 6: Congratualations! The dataset is downloaded.
Updates on 20 July 2023
We have now released the face crops. In case you have already downloaded this dataset before 20 July 2023, you may just download the face crops by following the given instruction here. If you encounter an error, please create an issue, I will look into it.
We provide supporting codes for easy access of the dataset. A dataloader written in PyTorch is available in avcaffe/codes/dataloader/. A minimum example usage is shown below and details usage is presented here:
db = AVCAffe(ROOT,
subset='train',
return_video=True,
video_clip_duration=2,
video_fps=16.,
return_audio=True,
audio_clip_duration=2,
audio_fps=16000,
return_labels=True,
class_name='mental_demand',
mode='clip',
clips_per_video=1,
)
sample = db.__getitem__(1)
We list some of the additional details here:
- the list of participants who agree to use their faces/images/videos for article or accopanied media contents, are available in
info/public_face_ids.txt. - participants used for training and validation splits are mentioned in
info/train.txtandinfo/val.txtrespectively. - the outcomes of prestudy questionnaire are available in
info/prestudy_response.csv. - some of the clips available in
shorter_segmentshave no speech when the participant were listening to the other participant or thinking or trying to solve the tasks, the file ids of such clips are available ininfo/no_audio_files.txt.
