Webscipy.interpolate.interpn(points, values, xi, method='linear', bounds_error=True, fill_value=nan) [source] #. Multidimensional interpolation on regular or rectilinear grids. Strictly speaking, not all regular grids are supported - this function works on rectilinear grids, that is, a rectangular grid with even or uneven spacing. WebDec 12, 2024 · I have a 3D array holding voxels from a mri dataset. The model could be stretched along one or more directions. E.g. the voxel size (x,y,z) could be 0.5×0.5×2 mm. Now I want to resample the 3D array into an array holding 1,1,1 mm voxels. For this I need to make the x/y dimensions smaller and the z dimension bigger and interpolate the voxel ...

WebCubic spline interpolation assumes that the line and the first derivative are continuous (for each point the first derivative is the same coming from both of the adjoining segments). If your function is well behaved (one x value maps to a unique y and z value) you should be able to just interpolate the y and z coordinates separately as then the ...
