darsia.AffineCorrection

class AffineCorrection(coordinatesystem_src, coordinatesystem_dst, pts_src, pts_dst, fit_options={})

Bases: TransformationCorrection

Affine correction (translation, scaling, rotation).

Set up the affine correction.

Parameters:

coordinatesystem_srcdarsia.CoordinateSystem

Coordinate system of pts_src.

coordinatesystem_dstdarsia.CoordinateSystem

Coordinate system of pts_dst.

pts_srcCoordinateArray, VoxelArray or VoxelCenterArray

Source points.

pts_dstCoordinateArray, VoxelArray or VoxelCenterArray

Target points.

fit_optionsdict, optional

"isometry" (bool) – whether the transformation is an isometry; if so it operates in Coordinate space.

Methods

correct_array(array_src)	Correction routine of array data.
correct_metadata([metadata])	Correction routine on metadata level.
load(path)	Load the correction from npz file.
save(path)	Save the correction to npz file.

Attributes

coordinatesystem_src	Coordinate system corresponding to the input.
coordinatesystem_dst	Coordinate system corresponding to the output/target.
dim	Dimension of the underlying Euclidean spaces.
transformation	Transformation to apply as correction.
