reslice_volume

Reslice one image volume along the planes of another.

Syntax:

resliced_volume=reslice_volume(A1, A2, IM1, IM2, padvalue, direction)

Description:

Reslices one image volume along the planes of another, using transformation matrices. The transformation can be used in a "forward" or a "reverse" direction. A1 - transformation matrix from IM1 coordinate frame to common coordinate frame (float, 4x4) A2 - transformation matrix from IM2 coordinate frame to common coordinate frame (float, 4x4) IM1 - image 1 (float, 2D or 3D) IM2 - image 2 (float, 2D or 3D) padvalue - the value to use for padding non-overlapped regions during re-slicing (float) direction - directions of transformation (int, >=0 / <0) >=0: "forward" reslicing, resliced_volume = IM2 -> IM1, transformation A = inv(A1)*A2 <0: "reverse" reslicing resliced_volume = IM1 -> IM2, transformation A = inv(A2)*A1 resliced_volume - resulting image (float, 2D or 3D)
