Method Details

dilate

public static ObjectMask dilate(ObjectMask object,
 Optional<Extent> extent,
 boolean useZ,
 int iterations,
 boolean bigNeighborhood)
                         throws CreateException

Dilates an ObjectMask, growing the bounding-box as necessary.

Parameters:

object - the object to dilate.

extent - if present, restricts the object to remain within certain bounds.

useZ - whether to perform dilation in 2D or 3D.

iterations - number of dilations to perform.

bigNeighborhood - if true, uses a big neighborhood, otherwise a small neighborhood, as defined in NeighborhoodFactory.

Returns:

a newly created object-mask with bounding-box dilated in relevant directions by iterations.

Throws:

CreateException - if the object cannot be successfully dilated.

dilate

public static BinaryVoxels<UnsignedByteBuffer> dilate(BinaryVoxels<UnsignedByteBuffer> voxels,
 int iterations,
 DilationContext context)
                                               throws CreateException

Performs a morphological dilation operation.

Parameters:

voxels - input-voxels.

iterations - number of dilations.

context - additional parameters for influencing how dilation occurs.

Returns:

a new buffer containing the results of the dilation-operations.

Throws:

CreateException - if the postcondition cannot be successfully checked.
