Constructor & Destructor Documentation

Data()

Data::Data ( const QString & dataPath )

explicit

Construct the data object from a tracking result file.

Parameters

[in]

dataPath

Path to the tracking data file.

Member Function Documentation

deleteData()

void Data::deleteData	(	int	objectId,
		int	from,
		int	to )

Delete the tracking data of one object from a selected index to the end.

• [in] objectId The object id.
• [in] from Start index from which the data will be deleted.
• [in] to End index from which the data will be deleted.

getData() [1/3]

QList< QHash< QString, double > > Data::getData

(

int

imageIndex

)

const

Get the tracking data at the selected image number.

Parameters

[in]

imageIndex

The index of the image where to extracts the data.

Returns

The tracking data at the selected image. The data are stored in a QList<QHash<dataName, value>>.

getData() [2/3]

QHash< QString, double > Data::getData	(	int	imageIndex,
		int	id ) const

Get the tracking data at the selected image number for one selected object.

Parameters

[in]	imageIndex	The index of the image where to extracts the data.
[in]	id	The id of the object.

Returns

The tracking data for the selected object at the selected image. The data are stored in a QHash<dataName, value>.

getData() [3/3]

QList< QHash< QString, double > > Data::getData	(	int	imageIndexStart,
		int	imageIndexStop,
		int	id ) const

Get the tracking data for a range of images and for one selected object.

Parameters

[in]	imageIndexStart	The index of the first image where to extracts the data.
[in]	imageIndexEnd	The index of the last image (excluded) where to extracts the data.
[in]	id	The id of the object.

Returns

The tracking data for the selected object at the selected image. The data are stored in a QHash<dataName, value>.

getDataId()

QHash< QString, QList< double > > Data::getDataId

(

int

id

)

const

Get the tracking data for the selected id.

Parameters

[in]

id

The id of the object.

Returns

The tracking data for for the selected object in a map with the key and a vector with the value for all the images.

getId() [1/2]

QList< int > Data::getId

(

int

imageIndex

)

const

Get the ids of all the objects in the frame.

• [in] imageIndex Index of the frame.

  Returns

getId() [2/2]

QList< int > Data::getId	(	int	imageIndexFirst,
		int	imageIndexLast ) const

Get the ids of all the objects in several frames.

• [in] imageIndexFirst Index of the first frame.
• [in] imageIndexLast Index of the last frame.

  Returns

  List of indexes.

getObjectInformation()

int Data::getObjectInformation

(

int

objectId

)

const

• [in] objectId Id of the object.

  Returns

  First appearance image index.

insertData()

void Data::insertData	(	int	objectId,
		int	from,
		int	to )

Insert the tracking data for one object from a selected index to the end.

• [in] objectId The object id.
• [in] from Start index from which the data will be swapped.
• [in] to End index from which the data will be swapped.

save()

void Data::save	(	bool	force = true,
		int	eachActions = 30 )

Save the data in the tracking result file.

Parameters

[in]	force	Force the saving.
[in]	eachActions	Save every eachActions actions.

setPath()

bool Data::setPath

(

const QString &

dataPath

)

Set the path to a tracking data file.

Parameters

[in]

dataPath

Path to the tracking data file.

swapData()

		int	secondObject,
		int	from )

In the tracking data, swaps two objects from a selected index to the end.

• [in] firstObject The first object id.
• [in] secondObject The second object id.
• [in] from Start index from which the data will be swapped.
