Detailed Description

Computes distance between images using MatchTemplate function from OpenCV library and its cross-correlation computation method in particular.

Constructor & Destructor Documentation

◆ MatchTemplateDistance()

cv::detail::tracking::tbm::MatchTemplateDistance::MatchTemplateDistance ( int  type = cv::TemplateMatchModes::TM_CCORR_NORMED,
float  scale = -1,
float  offset = 1 
)
inline

Constructs the distance object.

Parameters
[in]typeMethod of MatchTemplate function computation.
[in]scaleScale parameter for the distance. Final distance is computed as: scale * distance + offset.
[in]offsetOffset parameter for the distance. Final distance is computed as: scale * distance + offset.

Member Function Documentation

◆ compute() [1/2]

float cv::detail::tracking::tbm::MatchTemplateDistance::compute ( const cv::Mat descr1,
const cv::Mat descr2 
)
overridevirtual

Computes distance between image descriptors.

Parameters
[in]descr1First image descriptor.
[in]descr2Second image descriptor.
Returns
Distance between image descriptors.

Implements cv::detail::tracking::tbm::IDescriptorDistance.

◆ compute() [2/2]

std::vector<float> cv::detail::tracking::tbm::MatchTemplateDistance::compute ( const std::vector< cv::Mat > &  descrs1,
const std::vector< cv::Mat > &  descrs2 
)
overridevirtual

Computes distances between two descriptors in batches.

Parameters
[in]descrs1Batch of first descriptors.
[in]descrs2Batch of second descriptors.
Returns
Distances between descriptors.

Implements cv::detail::tracking::tbm::IDescriptorDistance.
