Image quality estimation#
The image quality estimation evaluates an image based on several key criteria to ensure it meets the necessary standards. These criteria include:
- Blurriness: The image appears out of focus.
- Underexposure: The image is too dark.
- Overexposure: The image is too bright.
To perform the estimation, LUNA ID uses the LUNA SDK SubjectiveQuality estimator. For details, see Image Quality Estimation.
