Member Function Documentation#

extractSelected()#

bool cv::detail::tracking::TrackerContribFeatureHAAR::extractSelected(
const std::vector< int > selFeatures,
const std::vector< Mat > & images,
Mat & response )

Compute the features only for the selected indices in the images collection.

Parameters

selFeatures — indices of selected features
images — The images
response — Collection of response for the specific TrackerContribFeature

getFeatureAt()#

CvHaarEvaluator::FeatureHaar & cv::detail::tracking::TrackerContribFeatureHAAR::getFeatureAt(int id)

Get the feature in position id.

Parameters

id — The position

selection()#

void cv::detail::tracking::TrackerContribFeatureHAAR::selection(
Mat & response,
int npoints )

Identify most effective features.

Note

This method modifies the response parameter

Parameters

response — Collection of response for the specific TrackerContribFeature
npoints — Max number of features

swapFeature()#

bool cv::detail::tracking::TrackerContribFeatureHAAR::swapFeature(
int id,
CvHaarEvaluator::FeatureHaar & feature )

Swap the feature in position id with the feature input.

Parameters

id — The position
feature — The feature

swapFeature()#

bool cv::detail::tracking::TrackerContribFeatureHAAR::swapFeature(
int source,
int target )

Swap the feature in position source with the feature in position target.

Parameters

source — The source position
target — The target position

computeImpl()#

bool cv::detail::tracking::TrackerContribFeatureHAAR::computeImpl(
const std::vector< Mat > & images,
Mat & response )
