## 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.

## Member Function Documentation

virtual Result<FSDKError> fsdk::IQualityEstimator::estimate | ( | const Image & | warp,
|  | Quality & | quality
| ) |  | const
| pure virtual noexcept

Estimate the quality.

Parameters

  [in] | warp | image with warped face. Format must be R8G8B8.
  [out] | quality | output structure with quality params. Complex quality estimation availible by method getQuality.

Returns
  Error code;

See Also
  FSDKError for details.

virtual Result<FSDKError> fsdk::IQualityEstimator::estimate | ( | const Image & | image,
|  | SubjectiveQuality & | quality
| ) |  | const
| pure virtual noexcept

Estimate the quality.

Parameters

  [in] | warp | image with warped face. Format must be R8G8B8.
  [out] | quality | output structure with subjective quality params.

Returns
  Error code;
