Detailed Description

Head pose angles estimator interface.

Note

This estimator is designed to work with 68 facial landmarks or with raw image data;

See Also

IDetector for details.

Estimated angles are:

• pitch;
• yaw;
• roll.

  See Also

  HeadPoseEstimation structure for details about how exactly the estimations are reported.
