ImageInterpolator
(image, order=3, mode='constant', cval=0.0)¶ 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, mode='constant', cval=0.0)¶ Parameters: image : Image
Image to be interpolated.
order : int, optional
order of spline interpolation as used in
scipy.ndimage
. Default is 3.mode : str, optional
Points outside the boundaries of the input are filled according to the given mode (‘constant’, ‘nearest’, ‘reflect’ or ‘wrap’). Default is ‘constant’.
cval : scalar, optional
Value used for points outside the boundaries of the input if mode=’constant’. Default is 0.0.

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
