nabu.preproc.distortion

source module nabu.preproc.distortion

Classes

• DistortionCorrection — A class for estimating and correcting image distortion.

Functions

• correct_distortion_interpn — Correct image distortion with scipy.interpolate.interpn.

source correct_distortion_interpn(image, coords, bounds_error=False, fill_value=None)

Correct image distortion with scipy.interpolate.interpn.

Parameters

• image : array — Distorted image

• coords : array — Coordinates of the distortion correction to apply, with the shape (Ny, Nx, 2)

source class DistortionCorrection(estimation_method='fft-correlation', estimation_kwargs=None, correction_method='interpn', correction_kwargs=None)
