inra.ijpb.binary.distmap.ChamferMask3DW3

public class ChamferMask3DW3
extends ChamferMask3D

Implementation of Chamfer Weights for 3D images that manages three type offset types, corresponding to orthogonal, square-diagonal and cube-diagonal neighbors. By default, computation is performed using integers.

Constructor Detail

ChamferMask3DW3

public ChamferMask3DW3(int w0,
                       int w1,
                       int w2)

Creates a new ChamferWeights3D object by specifying the weights associated to orthogonal, square-diagonal and cube-diagonal neighbors, respectively.

Parameters:

w0 - the weight associated to orthogonal neighbors

w1 - the weight associated to square-diagonal neighbors

w2 - the weight associated to cube-diagonal neighbors

ChamferMask3DW3

public ChamferMask3DW3(short[] weights)

Creates a new ChamferMask3D object by specifying the weights associated to orthogonal and diagonal neighbors.

Parameters:

weights - the weights associated to the different types of offset

Method Detail

getForwardOffsets

public Collection<ChamferMask3D.ShortOffset> getForwardOffsets()

Specified by:

getForwardOffsets in class ChamferMask3D

Returns:

the set of offsets defined by this ChamferWeights3D for forward iteration using integer weights.

getBackwardOffsets

public Collection<ChamferMask3D.ShortOffset> getBackwardOffsets()

Specified by:

getBackwardOffsets in class ChamferMask3D

Returns:

the set of offsets defined by this ChamferWeights3D for backward iteration using integer weights.

getShortNormalizationWeight

public short getShortNormalizationWeight()

Specified by:

getShortNormalizationWeight in class ChamferMask3D

Returns:

the weight associated to orthogonal offsets, that can be used to normalize the distance map.
