Class DisplacementFieldBlockSupplier<D extends net.imglib2.type.NativeType<D> & net.imglib2.type.numeric.RealType<D>,T extends net.imglib2.type.NativeType<T>>

java.lang.Object

net.imglib2.algorithm.blocks.AbstractBlockSupplier<T>

net.imglib2.algorithm.blocks.dfield.DisplacementFieldBlockSupplier<D,T>

Type Parameters:

D - displacement field type

T - target pixel type

All Implemented Interfaces:

BlockSupplier<T>, net.imglib2.EuclideanSpace, net.imglib2.Typed<T>

public class DisplacementFieldBlockSupplier<D extends net.imglib2.type.NativeType<D> & net.imglib2.type.numeric.RealType<D>,T extends net.imglib2.type.NativeType<T>>
extends AbstractBlockSupplier<T>

A BlockSupplier that combines a AbstractDispFieldAffineProcessor and a PositionFieldFunction to compute (blocks of) the transformation of a function with a displacement field.

The AbstractDispFieldAffineProcessor interpolates and affine transforms the displacement field to get a position field.

The PositionFieldFunction computes target values using the position field vectors.

Create a BlockSupplier that transforms displacementField into a position field and produces target values by applying positionFieldFunction to the resulting position vectors.

transformFromField is an affine transform from displacementField coordinates to target coordinates. For example, this can be used to upscale a downsampled displacement field.

Type Parameters:

D - displacement field type

T - the target type

Parameters:

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

displacementField - the (normalized) displacement field

positionFieldFunction - maps position vectors to target values

Returns:

a BlockSupplier that transforms displacementField into a position field and produces target values by applying positionFieldFunction to the resulting position vectors

copy

public void copy(net.imglib2.Interval interval,
                 Object dest)

Description copied from interface: BlockSupplier

Copy a block from the (T-typed) source into primitive arrays (of the appropriate type).

Parameters:

interval - the block to copy

dest - primitive array to copy into. Must correspond to T, for example, if T is UnsignedByteType then dest must be byte[].

numDimensions

public int numDimensions()

getType

public T getType()

independentCopy

public BlockSupplier<T> independentCopy()

Description copied from interface: BlockSupplier

Returns an instance of this BlockSupplier that can be used independently, e.g., in another thread or in another place in the same pipeline.
