java.lang.Object

inra.ijpb.binary.distmap.ChamferMask2D

inra.ijpb.binary.distmap.ChamferMask2DW2Float

public class ChamferMask2DW2Float
extends ChamferMask2D

Implementation of Chamfer Weights that manages two types of offsets, corresponding to orthogonal, and 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<ChamferMask2D.ShortOffset> getForwardOffsets()

Specified by:

getForwardOffsets in class ChamferMask2D

Returns:

the set of offsets defined by this ChamferMask2D for forward iteration using integer weights.

getBackwardOffsets

public Collection<ChamferMask2D.ShortOffset> getBackwardOffsets()

Specified by:

getBackwardOffsets in class ChamferMask2D

Returns:

the set of offsets defined by this ChamferMask2D for backward iteration using integer weights.

getForwardFloatOffsets

public Collection<ChamferMask2D.FloatOffset> getForwardFloatOffsets()

Overrides:

getForwardFloatOffsets in class ChamferMask2D

Returns:

the set of offsets defined by this ChamferMask2D for forward iteration using floating-point weights.

getBackwardFloatOffsets

public Collection<ChamferMask2D.FloatOffset> getBackwardFloatOffsets()

Overrides:

getBackwardFloatOffsets in class ChamferMask2D
