Detailed Description

Defines an affine transformation

Constructor & Destructor Documentation

cv::reg::MapAffine::MapAffine ( void )

Default constructor builds an identity map

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

cv::reg::MapAffine::~MapAffine ( void )

Destructor

Member Function Documentation

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.

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

inline

Return linear part of the affine transformation

Returns: Linear part of the affine transformation

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

inline

Return displacement part of the affine transformation

Returns: Displacement part of the affine transformation

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

virtual

Calculates the inverse map

Returns: Inverse map

Implements cv::reg::Map.

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.

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.
