Defines an transformation that consists on a projective transformation
cv::reg::MapProjec::MapProjec | ( | void | ) |
Default constructor builds an identity map
cv::reg::MapProjec::MapProjec | ( | const cv::Matx< double, 3, 3 > & | projTr | ) |
Constructor providing explicit values
[in] | projTr | Projective transformation |
cv::reg::MapProjec::~MapProjec | ( | void | ) |
Destructor
|
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.
[in] | map | Transformation to compose with. |
Implements cv::reg::Map.
|
inline |
Returns projection matrix
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.
[in] | img1 | Original image |
[out] | img2 | Warped image |
Implements cv::reg::Map.
|
inline |
Normalizes object's homography
|
virtual |
Scales the map by a given factor as if the coordinates system is expanded/compressed by that factor.
[in] | factor | Expansion if bigger than one, compression if smaller than one |
Implements cv::reg::Map.
