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.
- Background: Plain white, light grey, or light blue background with no objects.
- Image Brightness: The image should not be too bright or too dark.
- Hair: Hair must not cover the face.
- Headgear: Only dark-colored religious headgear that does not cover the face is acceptable.
Deployment
- All BQAT variants are packaged as Docker images and ready to be deployed as Docker containers.
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
