Detailed Description

A class for storing multiple object data objects. The object data objects are handled as a path. All objects are stored sorted ascending by their frame index.

Constructor & Destructor Documentation

core::Tracklet::Tracklet ( )

Creates a empty tracklet to store path object in. This is NOT a virtual object.

Member Function Documentation

void core::Tracklet::AddPathObject	(	ObjectDataPtr	obj,
		bool	overwrite = `false`
	)

Adds the path object sorted into the tracklet.

Parameters

obj	The path object to add
overwrite	If true and an object in the same frame as the given object already exists, the old one will be replaced by the new one

void core::Tracklet::Combine ( TrackletPtr other )

Copies all detections from the specified tracklet to this tracklet

Parameters

other The tracklet to copy the detections from

double core::Tracklet::CompareTo ( ObjectDataPtr obj ) const

overridevirtual

Compares this object with the given object.

Parameters

obj	A pointer to the object to compare this object to

Returns: A double value indicating the comparison result

Reimplemented from core::ObjectData.

void core::Tracklet::Flatten ( )

Flattens the current tracklet one level. That means, that if this tracklet contains other tracklets as path objects, their path objects are all extracted and used as the new path objects of this tracklet. The old tracklet path objects are removed.

size_t core::Tracklet::GetFirstFrameIndex ( ) const

Gets the lowest frame index of all path objects.

Returns: The lowest frame index

ObjectDataPtr core::Tracklet::GetFrameObject ( size_t frame_index )

Gets the detected object at the given frame index or a nullptr if there is not detection.

Parameters

frame_index The index of the frame to take the detection from

Returns: A pointer to the detection in the given frame

size_t core::Tracklet::GetLastFrameIndex ( ) const

Gets the highest frame index of all path objects.

Returns: The highest frame index

ObjectDataPtr core::Tracklet::GetPathObject ( size_t i )

Gets the path object at the given index. The index is NOT the frame index

Returns: A pointer to the path object

size_t core::Tracklet::GetPathObjectCount ( ) const

Gets the count of all path objects.

Returns: The path object count

ObjectDataPtr core::Tracklet::Interpolate	(	ObjectDataPtr	obj,
		double	fraction
	)		const

overridevirtual

Linearly interpolates between this and the given object. Creates a new object to fit between the two objects.

Parameters

obj	A pointer to the target object
fraction	Describes where the interpolation should be done. A fraction of zero is a clone of this object, a fraction of one is a clone of the target object.

Returns: The interpolated object

Reimplemented from core::ObjectData.

void core::Tracklet::InterpolateMissingFrames ( )

Interpolates between the current path objects until every missing frame has an object. Only frames between the first frame index and the last frame index are interpolated.

void core::Tracklet::Visualize	(	cv::Mat &	image,
		cv::Scalar &	color,
		size_t	frame,
		size_t	predecessor_count,
		size_t	successor_count
	)		const

Visualizes the tracklet by visualizing the path object in the given frame and the number of path objects in the given range before and after the given frame.

Parameters

image	The image to write into
color	The color to use
frame	The frame index to visualize the path objects from
predecessor_count	The number of path objects to visualize before the given frame
successor_count	The number of path objects to visualize after the given frame

void core::Tracklet::Visualize	(	cv::Mat &	image,
		cv::Scalar &	color
	)		const

overridevirtual

Visualizes the object in the given image with the given color. This method does nothing, it needs to be overwritten to visualize something.

Parameters

image	The image to write into
color	The color to use

Reimplemented from core::ObjectData.
