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]	type	Method of MatchTemplate function computation.
[in]	scale	Scale parameter for the distance. Final distance is computed as: scale * distance + offset.
[in]	offset	Offset parameter for the distance. Final distance is computed as: scale * distance + offset.
