Unification ct scan voxel size by using interpolation in Python

Question

I have used interp2 in Matlab, such as the following code, that is part of @rayryeng\'s answer in: Three dimensional (3D) matrix interpolation in Matlab:

Answer 1

You might be interested in scipy.ndimage.zoom. If you are interpolating from one regular grid to another, it is much faster and easier to use than scipy.interpolate.interp2d.

See this answer for an example: https://stackoverflow.com/a/16984081/1295595

You'd probably want something like:

import scipy.ndimage as ndimage
M2D = ndimage.zoom(volume_image, (1, scaleCoeff[0], scaleCoeff[1])
