Member Function Documentation#

init()#

bool cv::legacy::Tracker::init(
InputArray image,
const Rect2d & boundingBox )

Python:

cv.legacy.Tracker.init(image, boundingBox) -> retval

Initialize the tracker with a known bounding box that surrounded the target.

Parameters

image — The initial frame
boundingBox — The initial bounding box

Returns

True if initialization went succesfully, false otherwise

read()#

void cv::legacy::Tracker::read(const FileNode & fn)

Reads algorithm parameters from a file storage.

update()#

bool cv::legacy::Tracker::update(
InputArray image,
Rect2d & boundingBox )

Python:

cv.legacy.Tracker.update(image) -> retval, boundingBox

Update the tracker, find the new most likely bounding box for the target.

Parameters

image — The current frame
boundingBox — The bounding box that represent the new target location, if true was returned, not modified otherwise

Returns

True means that target was located and false means that tracker cannot locate target in current frame. Note, that latter does not imply that tracker has failed, maybe target is indeed missing from the frame (say, out of sight)

write()#

void cv::legacy::Tracker::write(FileStorage & fs)

Stores algorithm parameters in a file storage.

initImpl()#

bool cv::legacy::Tracker::initImpl(
const Mat & image,
const Rect2d & boundingBox )

updateImpl()#

bool cv::legacy::Tracker::updateImpl(
const Mat & image,
Rect2d & boundingBox )
