Detailed Description

Defines an transformation that consists on a simple displacement

Constructor & Destructor Documentation

cv::reg::MapShift::MapShift

(

void

)

Default constructor builds an identity map

cv::reg::MapShift::MapShift

(

const cv::Vec< double, 2 > &

shift

)

Constructor providing explicit values

Parameters

[in]

shift

Displacement

void

)

Destructor

Member Function Documentation

void cv::reg::MapShift::compose ( const 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.

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

inline

Return displacement

Returns

Displacement

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

virtual

Calculates the inverse map

Returns

Inverse map

Implements cv::reg::Map.

void cv::reg::MapShift::inverseWarp ( const cv::Mat &  img1, cv::Mat &  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.

Parameters

[in]	img1	Original image
[out]	img2	Warped image

Implements cv::reg::Map.

void cv::reg::MapShift::scale ( double  factor )

virtual

Scales the map by a given factor as if the coordinates system is expanded/compressed by that factor.

Parameters

[in]

factor

Expansion if bigger than one, compression if smaller than one

Implements cv::reg::Map.
