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
.-
__init__
(image, order=3, mode='constant', cval=0.0)¶ - Parameters
- imageImage
Image to be interpolated.
- orderint, optional
order of spline interpolation as used in
scipy.ndimage
. Default is 3.- modestr, optional
Points outside the boundaries of the input are filled according to the given mode (‘constant’, ‘nearest’, ‘reflect’ or ‘wrap’). Default is ‘constant’.
- cvalscalar, 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
- pointsarray
values in self.image.coordmap.output_coords. Each row is a point.
- Returns
- Vndarray
interpolator of self.image evaluated at points
