intersection
(i1, h1, i2, h2)[source]¶ Returns the intersecting parts of two images in real world coordinates. Takes both, voxelspacing and image offset into account.
Note that the returned new offset might be inaccurate up to 1/2 voxel size for each dimension due to averaging.
Parameters: i1 : array_like
i2 : array_like
The two images.
h1 : MedPy image header
h2 : MedPy image header
The corresponding headers.
Returns: v1 : ndarray
The intersecting part of
i1
.v2 : ndarray
The intersecting part of
i2
.offset : tuple of floats
The new offset of
v1
andv2
in real world coordinates.
