Detailed Description

Defines an transformation that consists on a simple displacement

Constructor & Destructor Documentation

◆ MapShift() [1/2]

cv::reg::MapShift::MapShift ( )

Default constructor builds an identity map

◆ MapShift() [2/2]

cv::reg::MapShift::MapShift ( InputArray shift )

Constructor providing explicit values

Parameters

[in] shift Displacement

◆ ~MapShift()

cv::reg::MapShift::~MapShift ( )

Destructor

Member Function Documentation

◆ compose()

void cv::reg::MapShift::compose ( cv::Ptr< Map > map )

virtual

Changes the map composing the current transformation with the one provided in the call. The order is first the current transformation, then the input argument.

Parameters

[in] map Transformation to compose with.

Implements cv::reg::Map.

◆ getShift() [1/2]

const cv::Vec< double, 2 > & cv::reg::MapShift::getShift ( ) const

inline

Return displacement

Returns: Displacement

◆ getShift() [2/2]

void cv::reg::MapShift::getShift ( OutputArray shift ) const

inline

◆ inverseMap()

cv::Ptr< Map > cv::reg::MapShift::inverseMap ( ) const

virtual

Calculates the inverse map

Returns: Inverse map

Implements cv::reg::Map.

◆ inverseWarp()

void cv::reg::MapShift::inverseWarp	(	InputArray	img1,
		OutputArray	img2
	)		const

virtual

Warps image to a new coordinate frame. The calculation is img2(x)=img1(T(x)), so in fact this is the inverse warping as we are taking the value of img1 with the forward transformation of the points.
