Member Function Documentation

on_frame_process_error()

virtual void face_sdk::itracker_events::on_frame_process_error ( const face_sdk::exception &  exc, const std::shared_ptr< face_sdk::video_stream > &  stream, const std::shared_ptr< face_sdk::video_frame > &  frame  )

pure virtual

Raises when failed to process frame in stream.

Parameters

[in]	exc	The exception. Use format_exception function to get error contents
[in]	stream	The stream to which the exception was thrown
[in]	frame	The invalid frame

on_track_appeared()

virtual void face_sdk::itracker_events::on_track_appeared ( const std::shared_ptr< face_sdk::video_stream > &  stream, const std::shared_ptr< face_sdk::track > &  track, const std::shared_ptr< face_sdk::video_frame > &  frame, const std::shared_ptr< face_sdk::face > &  face  )

pure virtual

Raises when a person has appeared in the stream.

Parameters

[in]	stream	The stream where a person has detected
[in]	track	The track of a person
[in]	frame	The frame where a person has detected
[in]	face	The detected face object in the frame

Examples:

tracker.cpp.

on_track_best_frame()

virtual void face_sdk::itracker_events::on_track_best_frame ( const std::shared_ptr< face_sdk::video_stream > &  stream, const std::shared_ptr< face_sdk::track > &  track, const std::shared_ptr< face_sdk::video_frame > &  frame, const std::shared_ptr< face_sdk::face > &  face  )

pure virtual

Raises when the track object find new best face.

Parameters

[in]	stream	The stream where the track object has updated
[in]	track	The updated track
[in]	frame	The frame where track has updated
[in]	face	The detected new best face in the frame

Examples:

tracker.cpp.

on_track_disappeared()

virtual void face_sdk::itracker_events::on_track_disappeared ( const std::shared_ptr< face_sdk::video_stream > &  stream, const std::shared_ptr< face_sdk::track > &  track  )

pure virtual

Raises when a person is lost in the stream.

Parameters

[in]	stream	The stream where a person is lost
[in]	track	The track of a person

Examples:

tracker.cpp.

on_track_updated()

virtual void face_sdk::itracker_events::on_track_updated ( const std::shared_ptr< face_sdk::video_stream > &  stream, const std::shared_ptr< face_sdk::track > &  track, const std::shared_ptr< face_sdk::video_frame > &  frame, const std::shared_ptr< face_sdk::face > &  face  )

pure virtual

Raises when the track object has updated.

Parameters

[in]	stream	The stream where the track object has updated
[in]	track	The updated track
[in]	frame	The frame where track has updated
[in]	face	The detected face in the frame

Examples:

tracker.cpp.
