Detailed Description

ImageViz SoImagePreAlignmentTransform3d image filter

SoImagePreAlignmentTransform3d estimates a transformation (translation and rotation) that aligns a moving image with a fixed image based on their intensity values. This transformation is particularly useful as an initial transformation value for the IntensityParametricRegistration engine.

SoImagePreAlignmentTransform3d first computes the centers of gravity and (optionally) the principal axes of both images (model and reference) using the image intensity values as a mass density. In the second step, the translation and the rotation that align the centers of gravity and the principal axes of both images are estimated. Note that if the computation of principal axes is omitted, only a translation is estimated.
