Detailed Description

Leaf node for ImageMath expressions that represents a deformation (cf Deformation).

Note: To apply a deformation to an image, use the Resample leaf which modifies the coordinates in an expression, this leaf only provides the displacement field.

Constructor & Destructor Documentation

◆ DeformationLeaf()

DeformationLeaf	(	SharedImage &	img,
		std::shared_ptr< Deformation >	deformation )

inline

Use a Deformation as an ImageMath leaf that can be used in ImageMath expressions.

The output of this leaf is the displacement in world coordinates Example, herere si is a SharedImage object:

std::shared_ptr<Deformation> def = si.deformation();
auto defExpr = DeformationLeaf(si,def);
auto defExprX = defExpr.x();

Warning: The CPU implementation calls displacePoint() once for each channel.

Parameters

image must be provided because the Deformation interface requires it.
