Public Attributes
int64_t	stream_id
	Integer id of the video stream (0 <= stream_id < streams_count).
int64_t	frame_id
	Integer id of the frame (that was returned by VideoWorker::addVideoFrame).
std::vector< RawSample::Ptr >	samples
	Vector of face samples found by the tracker. Most of the samples are received from the frame_id frame but some samples can be received from the previous frames. Use RawSample::getFrameID to determine which frame the sample belongs to.
std::vector< int >	samples_track_id
	Vector of face IDs (track_id). track_id is equal to sample.getID() for the sample given in any VideoWorker callback. (samples_track_id.size() == samples.size())
std::vector< bool >	samples_weak
	Since this is tracking, some samples may be false, so we mark the samples with the "weak" flag if they haven’t passed one of the rechecks (see: samples_good_face_size, samples_good_angles, samples_depth_liveness_confirmed, samples_ir_liveness_confirmed, samples_detector_confirmed, samples_good_light_and_blur). "Weak" samples are not used for recognition (samples_weak.size() == samples.size())
std::vector< float >	samples_quality
	Quality value for the face sample. The same as from the FaceQualityEstimator (samples_quality.size() == samples.size())
std::vector < SampleCheckStatus::Verdict >	samples_good_light_and_blur
	The result of checking the sample for good lighting conditions and absence of a strong blur (samples_good_light_and_blur.size() == samples.size())
std::vector < SampleCheckStatus::Verdict >	samples_good_angles
	The result of checking the sample for absence of too high yaw/pitch angles (samples_good_angles.size() == samples.size())
std::vector < SampleCheckStatus::Verdict >	samples_good_face_size
	The result of checking the sample for suitable face size, see the min_template_generation_face_size parameter in config file. (samples_good_face_size.size() == samples.size())
std::vector < SampleCheckStatus::Verdict >	samples_detector_confirmed
	The result of checking the sample with the frontal face detector (samples_detector_confirmed.size() == samples.size())
std::vector < DepthLivenessEstimator::Liveness >	samples_depth_liveness_confirmed
	The result of checking the sample with DepthLivenessEstimator, depth frames are required, see VideoWorker::addDepthFrame. See DepthLivenessEstimator::Liveness for details. (samples_depth_liveness_confirmed.size() == samples.size())
std::vector < IRLivenessEstimator::Liveness >	samples_ir_liveness_confirmed
	The result of checking the sample with IRLivenessEstimator, IR frames are required, see VideoWorker::addIRFrame. See IRLivenessEstimator::Liveness for details. (samples_ir_liveness_confirmed.size() == samples.size())
std::vector< bool >	samples_track_age_gender_set
	Flag indicating that age and gender were estimated for this track. (samples_track_age_gender_set.size() == samples.size())
std::vector < AgeGenderEstimator::AgeGender >	samples_track_age_gender
	Estimated age and gender for this track. (samples_track_age_gender.size() == samples.size())
std::vector< bool >	samples_track_emotions_set
	Flag indicating that emotions were estimated for this track. (samples_track_emotions_set.size() == samples.size())
std::vector < EmotionsEstimator::EstimatedEmotionsVector >	samples_track_emotions
	Estimated emotions for this track. (samples_track_emotions.size() == samples.size())
std::vector < ActiveLiveness::ActiveLivenessStatus >	samples_active_liveness_status
	Face active liveness check status. See ActiveLiveness::ActiveLivenessStatus for details. (samples_active_liveness_status.size() == samples.size())
