Detailed Description

template<typename TScalar = double>
class itk::CenteredSimilarity2DTransform< TScalar >

CenteredSimilarity2DTransform of a vector space (e.g. space coordinates)

This transform applies a homogenous scale and rigid transform in 2D space. The transform is specified as a scale and rotation around a arbitrary center and is followed by a translation. given one angle for rotation, a homogeneous scale and a 2D offset for translation.

The main difference between this class and its superclass Similarity2DTransform is that the center of transformation is exposed for optimization.

The serialization of the optimizable parameters is an array of 6 elements ordered as follows: p[0] = scale p[1] = angle p[2] = x coordinate of the center p[3] = y coordinate of the center p[4] = x component of the translation p[5] = y component of the translation

There are no fixed parameters.
