Interpolate and transform blocks of the standard ImgLib2 RealTypes using an affine-transformed displacement field.

Only 2D and 3D are supported currently!

The returned factory function creates an operator matching the type a given input BlockSupplier<T>.

Type Parameters:

D - displacement field type

T - the source/target type

Parameters:

transformFromField - a 2D or 3D affine transform from displacementField coordinates to target coordinates

displacementField - the (normalized) displacement field

interpolation - which interpolation method to use for lookup in the source image. (displacement field is always linearly interpolated)

Returns:

factory for UnaryBlockOperator to transform blocks of type T

Interpolate and transform blocks of the standard ImgLib2 RealTypes using an affine-transformed displacement field.

Only 2D and 3D are supported currently!

The returned factory function creates an operator matching the type a given input BlockSupplier<T>.

Type Parameters:

D - displacement field type

T - the source/target type

Parameters:

transformFromField - a 2D or 3D affine transform from displacementField coordinates to target coordinates

displacementField - the (normalized) displacement field

interpolation - which interpolation method to use for lookup in the source image. (displacement field is always linearly interpolated)

computationType - For n-linear interpolation, this specifies in which precision intermediate values should be computed. For AUTO, the type that can represent the input/output type without loss of precision is picked. That is, FLOAT for u8, i8, u16, i16, i32, f32, and otherwise DOUBLE for u32, i64, f64. For nearest-neighbor interpolation, computationType is not used.

Returns:

Combines an affine transformation into a (linearly interpolated) displacement field, and look-up with resulting position field vectors in a source image of type T, to produce an output image of type T.

Type Parameters:

D - displacement field type

T - the source/target type

Parameters:

type - instance of the source/target type

transformFromField - a 2D or 3D affine transform from displacementField coordinates to target coordinates

displacementField - the (normalized) displacement field

interpolation - which interpolation method to use for lookup in the source image. (displacement field is always linearly interpolated)

computationType - For n-linear interpolation, this specifies in which precision intermediate values should be computed. For AUTO, the type that can represent the input/output type without loss of precision is picked. That is, FLOAT for u8, i8, u16, i16, i32, f32, and otherwise DOUBLE for u32, i64, f64. For nearest-neighbor interpolation, computationType is not used.

clampType - For n-linear interpolation this specifies how interpolated values (which are always float or double) should be clamped when converting back to the source/target type. For nearest-neighbor interpolation, clampType is not used.
