Detailed Description

Defines an affine transformation

Constructor & Destructor Documentation

MapAffine() [1/2]

cv::reg::MapAffine::MapAffine

(

void

)

Default constructor builds an identity map

MapAffine() [2/2]

cv::reg::MapAffine::MapAffine	(	const cv::Matx< double, 2, 2 > &	linTr,
		const cv::Vec< double, 2 > &	shift
	)

Constructor providing explicit values

Parameters

[in]	linTr	Linear part of the affine transformation
[in]	shift	Displacement part of the affine transformation

Member Function Documentation

compose()

void cv::reg::MapAffine::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.

getLinTr()

const cv::Matx<double, 2, 2>& cv::reg::MapAffine::getLinTr

(

)

const

Return linear part of the affine transformation

Returns

Linear part of the affine transformation

getShift()

const cv::Vec<double, 2>& cv::reg::MapAffine::getShift

(

)

const

Return displacement part of the affine transformation

Returns

Displacement part of the affine transformation

inverseMap()

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

virtual

Calculates the inverse map

Returns

Inverse map

Implements cv::reg::Map.

inverseWarp()

void cv::reg::MapAffine::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.

scale()

void cv::reg::MapAffine::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.
