Class ChamferMask3DW3Float

java.lang.Object

inra.ijpb.binary.distmap.ChamferMask3D

inra.ijpb.binary.distmap.ChamferMask3DW3Float

public class ChamferMask3DW3Float
extends ChamferMask3D

Implementation of Chamfer Weights for 3D images that manages three types of offsets, corresponding to orthogonal, square-diagonal and cube-diagonal neighbors. This implementation manages two series of weights, one for integer computation, the other one for floating-point computation.

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.

getForwardFloatOffsets

public Collection<ChamferMask3D.FloatOffset> getForwardFloatOffsets()

Overrides:

getForwardFloatOffsets in class ChamferMask3D

Returns:

the set of offsets defined by this ChamferWeights3D for forward iteration using floating-point weights.

getBackwardFloatOffsets

public Collection<ChamferMask3D.FloatOffset> getBackwardFloatOffsets()

Overrides:

getBackwardFloatOffsets in class ChamferMask3D
