Interface ResolutionLevel3D<T>

Type Parameters:

T - pixel type

All Superinterfaces:

net.imglib2.EuclideanSpace, Typed<T>

public interface ResolutionLevel3D<T>
extends net.imglib2.EuclideanSpace, Typed<T>

One resolution level of a MultiResolutionStack3D

This may be used as part of a cache key, so equals() and hashCode() should be overridden such that ResolutionLevel3Ds referring the same image data are equal.

Method Summary

Modifier and Type	Method and Description
net.imglib2.RandomAccessibleInterval<T>	getImage() Get the image data for this resolution level.
int	getLevel() Get the index of this resolution level in the MultiResolutionStack3D By default, index 0 is the full resolution, and resolution level at index i>j has lower resolution (more down-sampled) than index j.
net.imglib2.realtransform.AffineTransform3D	getLevelTransform() Get the transformation from image coordinates of this level to image coordinates of level 0 (full resolution).
int[]	getR() Get per-dimension down-sampling factors with respect to full resolution.
double[]	getS() Get per-dimension scale factors with respect to full resolution.
default int	numDimensions()

Method Detail

getLevel

int getLevel()

Get the index of this resolution level in the MultiResolutionStack3D By default, index 0 is the full resolution, and resolution level at index i>j has lower resolution (more down-sampled) than index j.

Returns:

index of resolution level

getR

int[] getR()

Get per-dimension down-sampling factors with respect to full resolution.

Returns:

down-sampling factors

getS

double[] getS()

Get per-dimension scale factors with respect to full resolution. This must always be the inverse of getR(), i.e., getS()[i] == 1.0 / getR()[i].

Returns:

scale factors

getLevelTransform

net.imglib2.realtransform.AffineTransform3D getLevelTransform()

Get the transformation from image coordinates of this level to image coordinates of level 0 (full resolution). For DEFAULT_BLOCK_AVERAGE down-sampling this is

     rx   0   0  (rx-1)/2
      0  ry   0  (ry-1)/2
      0   0  rz  (rz-1)/2
 

Returns:

transformation from image coordinates of this level to image coordinates of level 0 (full resolution).

getImage

net.imglib2.RandomAccessibleInterval<T> getImage()

Get the image data for this resolution level.

Returns:

image data for this level.

numDimensions

default int numDimensions()

Specified by:

numDimensions in interface net.imglib2.EuclideanSpace
