Supported biometric modalities include:

Fingerprint
Face
Iris
Voice

Output Results

Results are provided in CSV format.

EDA Report

Includes exploratory data analysis (EDA) of biometric sample quality.

Quality Metrics (Face)

Customised Attributes:

Position: Image is vertically and horizontally centered.
Composition: Minimum 50% of the image must contain the face.
Eye: Eyes must be open, visible, looking straight into the camera, and free of red-eye.
Expression: Neutral or slight smile (with lips closed).
Head Orientation: Variability is no more than 5% in any three directions.
Shadow: No shadows on the image.

Prerequisites:

Windows / Linux (preferred)
Docker engine installed

Installation:

Refer to the manual to download Docker containers and run BQAT.

Potential Technical Errors

"Server not found": Verify the URL.
Frozen tasks: If the BQAT task is taking too long, large datasets may require more processing time. If significantly delayed, cancel and restart the task.

Outlier Detection (Beta)

Beta feature for identifying outliers based on metrics.
Multiple outlier detection algorithms available.
Consistent algorithm usage is recommended.

Example:

Metric: "Head size"
- Bigger than others
- Smaller than others
