Public Attributes
ulong	stream_id
	Integer id of the video stream (0 <= stream_id < streams_count).
ulong	frame_id
	Integer id of the frame (that was returned by VideoWorker.addVideoFrame).
RawSample[]	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.
int[]	samples_track_id
	Vector of face IDs (track_id). track_id is equal to sample.getID() for a sample given in any VideoWorker callback. (samples_track_id.Length == samples.Length)
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_detector_confirmed, samples_good_light_and_blur). "Weak" samples are not used for recognition (samples_weak.Length == samples.Length)
float[]	samples_quality
	Quality value for the face sample. The same as from the FaceQualityEstimator (samples_quality.Length == samples.Length)
SampleCheckStatus[]	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.Length == samples.Length)
SampleCheckStatus[]	samples_good_angles
	The result of checking the sample for absence of too high yaw/pitch angles (samples_good_angles.Length == samples.Length)
SampleCheckStatus[]	samples_good_face_size
	The result of checking the sample for suitable size of a face, see the min_template_generation_face_size parameter in the configuration file. (samples_good_face_size.Length == samples.Length)
SampleCheckStatus[]	samples_detector_confirmed
	The result of checking the sample with the frontal face detector (samples_detector_confirmed.Length == samples.Length)
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.Length == samples.Length)
bool[]	samples_track_age_gender_set
	Flag indicating that age and gender were estimated for this track. (samples_track_age_gender_set.Length == samples.Length)
AgeGenderEstimator.AgeGender[]	samples_track_age_gender
	Estimated age and gender for this track. (samples_track_age_gender.Length == samples.Length)
bool[]	samples_track_emotions_set
	Flag indicating that emotions were estimated for this track. (samples_track_emotions_set.Length == samples.Length)
List < EmotionsEstimator.EmotionConfidence >[]	samples_track_emotions
	Estimated emotions for this track. (samples_track_emotions.Length == samples.Length)
ActiveLiveness.ActiveLivenessStatus[]	samples_active_liveness_status
	Face active liveness check status. See ActiveLiveness::ActiveLivenessStatus for details. (samples_active_liveness_status.size() == samples.size())
