Detailed Description

Function Documentation

def face_sdk.modules.video_worker.SearchResult.__init__	(	self,
		person_id
	)

Unique id of the person.

Unique id of the element.

Result of template matching.

def face_sdk.modules.video_worker.TrackingCallbackData.__init__ ( self )

Integer id of the video stream (0 <= stream_id < streams_count).

Integer id of the frame (that was returned by VideoWorker.add_video_frame).

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.get_frame_id to determine which frame the sample belongs to.

Vector of face IDs (track_id). track_id is equal to sample.get_id() for the sample given in any VideoWorker callback. (samples_track_id.size() == samples.size())

Since this is tracking, some samples may be false, so we mark the samples with the "weak" flag if they haven’t passed the recheck with the frontal face detector. Weak samples are not used for recognition (samples_weak.size() == samples.size())

Quality value for the face sample. The same as from the FaceQualityEstimator (samples_quality.size() == samples.size())

The result of checking the sample for good lighting conditions and absence of a strong blur (samples_good_light_and_blur.size() == samples.size())

The result of checking the sample for absence of too high yaw/pitch angles (samples_good_angles.size() == samples.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. len(samples_good_face_size) == len(samples)

The result of checking the sample with the frontal face detector len(samples_detector_confirmed) == len(samples.size()

The result of checking the sample with DepthLivenessEstimator, depth frames are required, see VideoWorker.addDepthFrame. See face_sdk_3divi.modules.depth_liveness_estimator.Liveness for details. len(samples_depth_liveness_confirmed) == len(samples)

The result of checking the sample with IRLivenessEstimator, depth frames are required, see VideoWorker.addIRFrame. See face_sdk_3divi.modules.ir_liveness_estimator.Liveness for details. len(samples_ir_liveness_confirmed) == samples.size)

Flag indicating that age and gender were estimated for this track. len(samples_track_age_gender_set) == len(samples)

Estimated age and gender for this track. len(samples_track_age_gender) == len(samples)

Flag indicating that emotions were estimated for this track. len(samples_track_emotions_set) == len(samples)

Estimated emotions for this track. len(samples_track_emotions) == len(samples)

Face active liveness check status. See ActiveLiveness::ActiveLivenessStatus for details. (samples_active_liveness_status.size() == samples.size())

Face sample.

Template created for this sample.

def face_sdk.modules.video_worker.MatchFoundCallbackData.__init__	(	self,
		stream_id
	)

Found elements with a distance less than distance_threshold (but not more than k nearest elements, the value of k is set in the configuration file tagged as search_k tag).

When called after N consecutive mismatches, the first element in search_results will have a zero distance, and person_id and element_id are equal to face_sdk_3divi.modules.video_worker.MATCH_NOT_FOUND_ID.

def face_sdk.modules.video_worker.TrackingLostCallbackData.__init__ ( self )

Integer id of the video stream (0 <= stream_id < streams_count).

Integer id of the frame on which the face was first detected.

Integer id of the frame after which the face tracking was lost.

Best sample quality over all frames.

Integer id of the frame of the best quality.

ID of the lost face (track_id). track_id is equal to sample.get_id() for a sample given in any VideoWorker callback.

The best quality sample from the best_quality_frame_id frame. Will be NULL if "weak_tracks_in_tracking_callback" is enabled and all samples with that track_id are flagged as "weak=true".

Template created from best_quality_sample. Will be NULL if processing_threads_count is zero or best_quality_sample is NULL.

Flag indicating that sti_person_id is set. sti_person_id is not set, if short time identification is disabled or no templates were generated for this track.

ID of "sti_person", which is a set of tracks formed by short time identification. sti_person_id is equal to track_id of the first member of this "sti_person" set of tracks.

def face_sdk.modules.video_worker.StiPersonOutdatedCallbackData.__init__	(	self,
		stream_id,
		sti_person_id
	)

def face_sdk.modules.video_worker.DatabaseElement.__init__	(	self,
		element_id
	)

Unique id of the element.

Unique id of the person.

Face template.

Distance threshold for a MatchFound event.

 Setting a different recognition threshold for different persons may be useful in some cases.
 For example, if there is a particular criminal in the blacklist, who is more dangerous
 than the other criminals, and you want to increase the recognition probability for this very person,
 despite the higher probability of a false acceptance error.

Reset work state for the stream.

It waits for the callbacks, which are currently being executed, therefore, do not synchronize the resetStream call with the code inside the callbacks, otherwise it can cause a deadlock. After resetStream is executed, no callbacks related to the previous frames or tracks will be called. It is necessary to release the memory allocated for all tracks with track_id less than the return value, since there will be no TrackingLost callback for the tracks removed during this reset. Thread-safe.

Parameters

[in] stream_id Integer id of the video stream (0 <= stream_id < streams_count).

Returns: Integer track_id_threshold, which means that all tracks that were removed during resetStream had track_id < track_id_threshold, and all new tracks will have track_id >= track_id_threshold.
