Image interpolators using ndimage.

ImageInterpolator

class nipy.algorithms.interpolation.ImageInterpolator(image, order=3)

Bases: object

Interpolate Image instance at arbitrary points in world space

The resampling is done with scipy.ndimage.

Methods

evaluate(points) Resample image at points in world space
__init__(image, order=3)
Parameters :

image : Image

Image to be interpolated

order : int, optional

order of spline interpolation as used in scipy.ndimage. Default is 3.

evaluate(points)

Resample image at points in world space

Parameters :

points : array

values in self.image.coordmap.output_coords. Each row is a point.

Returns :

V : ndarray

interpolator of self.image evaluated at points
