Evaluation
Primary metric: Equal Error Rate (EER)
Participants must submit a JSON file like:
{
"video_file": "sample_01.mp4",
"score": 0.87,
"user_id": "U001",
"spoken_word": "open"
}
Dataset Structure
Each user has a folder with multiple videos containing correct and incorrect passphrases. The system must identify valid users and reject impostors or invalid phrases.
Example of the Training Set filename format: <ID>_<NUM_PROG>_<T/F>.mp4, where ID is the user identifier, NUM_PROG is the progressive number, and T/F indicates whether the video contains a correct (T) or incorrect (F) passphrase.
Research Topics
Lip feature extraction
Audio-visual fusion
Temporal modeling
Privacy-preserving authentication
Cross-device generalization
Explainability
Rules
- Participants can receive the training set and its annotations after team registration
- The test set will be released after the submission of 1 page abstract about the method.
- Particpant will submit the test results (in JSON) format within 5 days after test set release.
- The participants are strongly encouraged to submit a paper by the deadline of 30th June, 2025 (extended).
The paper can be submitted through OpenReview (link soon available). Authors can find complete instructions of how to format their papers here. The maximum number of pages is 12 including references. Accepted papers will be included in the ICIAP 2025 Workshops Proceedings. Camera-ready submission: July 10th, 2025 (extended)
