imref3d
Reference 3-D image to world coordinates
Description
An imref3d
object stores the relationship between the
intrinsic coordinates anchored to the columns, rows, and planes of a 3-D image and the
spatial location of the same column, row, and plane locations in a world coordinate
system.
The image is sampled regularly in the planar world-x, world-y, and world-z coordinates of the coordinate system such that intrinsic-x, -y and -z values align with world-x, -y, and -z values, respectively. The resolution in each dimension can be different.
Creation
You can create an imref3d
object in these ways.
affineOutputView
— Store the spatial extent of an image that is warped by a 3-D affine geometric transformation.The
