TrackingPointSelector() [2/2]

TrackingPointSelector::TrackingPointSelector	(	std::vector< cv::Point2f >	pts,
		int	width,
		int	height,
		int	markerTemplateWidth,
		int	width0,
		int	height0 )

Parameters

pts	Location of Harris corners in the image.
width	Width of the image in which pts are measured.
height	Height of the image in which pts are measured.
width0	Width of the image at level 0 of the image pyramid. If larger than width (i.e. width does not represent level 0), the output of all Get*Features*() functions will be scaled to level 0 image dimensions.
height0	Height of the image at level 0 of the image pyramid. If larger than height (i.e. height does not represent level 0, the output of all Get*Features*() functions will be scaled to level 0 image dimensions.

CleanUp()

void TrackingPointSelector::CleanUp

(

)

DistributeBins()

void TrackingPointSelector::DistributeBins

(

int

markerTemplateWidth

)

Iterates over _pts, the location of Harris corners in the image, and for each one, provided it doesn't intersect the image border, creates a TrackedPoint representing a template with a serially-increasing id from 0, and put it into the trackingPointsBin structure (a vector of pairs of (binIndex, trackingPoint)).

GetAllFeatures()

std::vector< cv::Point2f > TrackingPointSelector::GetAllFeatures

(

)

Get all points from all bins that are candidates for selection.

GetInitialFeatures()

std::vector< cv::Point2f > TrackingPointSelector::GetInitialFeatures

(

)

If reset, then selects an initial random template from each bin for tracking, and returns this set.

If not reset then returns the same set as GetTrackedFeatures.

Here is the call graph for this function:

GetTrackedFeatures()

std::vector< cv::Point2f > TrackingPointSelector::GetTrackedFeatures

(

)

GetTrackedFeatures3d()

std::vector< cv::Point3f > TrackingPointSelector::GetTrackedFeatures3d

(

)

GetTrackedFeaturesWarped()

std::vector< cv::Point2f > TrackingPointSelector::GetTrackedFeaturesWarped

(

const cv::Mat &

homography

)

Gets the projected location in the video frame of the currently tracked features, when projected via the supplied homography.

Parameters

3x3	cv::Mat (of type CV_64FC1, i.e. double) containing the homography.

Here is the call graph for this function:

ResetSelection()

void TrackingPointSelector::ResetSelection

(

)

Signal that the next call to GetInitialFeatures should return a new selection.

UpdatePointStatus()

void TrackingPointSelector::UpdatePointStatus

(

std::vector< uchar >

status

)
