Detailed Description

mitkScaleTransform - a concrete transform to perform anisotropic scaling transform

mitkScaleTransform is a concrete transform to perform anisotropic scaling transform to 2D and 3D image space. User should use the constructor to specify the image dimensions, e.g. mitkScaleTransform(2) (default) for 2d image, mitkScaleTransform(3) for 3d image. To improve the behavior of the scaling parameters when they are modified by optimizers, a logarithm based scaling transform was implemented.

Transform Mode Number of parameters p[0] p[1] p[2]

MITK_TRANSFORM_SCALE (2D) 2 sx sy -

MITK_TRANSFORM_SCALE (3D) 3 sx sy sz

MITK_TRANSFORM_SCALE_LOGARITHMIC (2D) 2 sx sy -

MITK_TRANSFORM_SCALE_LOGARITHMIC (3D) 3 sx sy sz
