Detailed Description

template<typename TPixel, int iDimension>
class FREE::CenterInitializer< TPixel, iDimension >

CenterInitializer is a helper class intended to calculate the center of an image.

CenterInitializer is a helper class intended to calculate the center of an image via two ways:

• Geometrically,
• via center of mass

In the first mode, the geometrical center of the image is passed as center. This mode basically assumes that the anatomical objects to be registered are centered in their respective images. Hence the best initial guess for the registration is the one that superimposes those two centers.

In the second mode, the moments of gray level values are computed for the images. The center of mass is then used as center of rotation. The vector between the two centers of mass is passed as the initial translation to the transform. This second approach assumes that the moments of the anatomical objects are similar for both images and hence the best initial guess for registration is to superimpose both mass centers. Note that this assumption will probably not hold in multi-modality registration.
