Detailed Description

Image quality estimator interface.

Note:
This estimator is designed to work with a person face image; you should pass a warped face detection image.
See also:
IWarper for details. Quality estimator detects the same attributes as all the other estimators:
  • over/under exposure;
  • blurriness;
  • natural/unnatural colors; It is different in the sense that it computes all the estimations at once and returns the results merged somehow into a single value instead of several separate values. This way one can obtain a single scalar quality metric of a person face image. The estimated value is a probability that the image is good for both recognition and viewing purposes.
