DistanceTransform3D4WeightsFloat

public DistanceTransform3D4WeightsFloat(ChamferWeights3D weights)

Deprecated.

Default constructor that specifies the chamfer weights.

Parameters:

weights - an array of four weights direction orthogonal, diagonal, cube diagonal, and (+-2,+-1,+-1).

DistanceTransform3D4WeightsFloat

public DistanceTransform3D4WeightsFloat(float[] weights)

Deprecated.

Default constructor that specifies the chamfer weights.

Parameters:

weights - an array of four weights direction orthogonal, diagonal, cube diagonal, and (+-2,+-1,+-1).

DistanceTransform3D4WeightsFloat

public DistanceTransform3D4WeightsFloat(ChamferWeights3D weights,

DistanceTransform3D4WeightsFloat

public DistanceTransform3D4WeightsFloat(float[] weights,

Deprecated.

Constructor specifying the chamfer weights and the optional normalization.

Parameters:

weights - an array of two weights for orthogonal and diagonal directions

normalize - flag indicating whether the final distance map should be normalized by the first weight

Method Details

distanceMap

public ij.ImageStack distanceMap(ij.ImageStack image)

Deprecated.

Computes the distance map from a 3D binary image. Distance is computed for each foreground (white) pixel, as the chamfer distance to the nearest background (black) pixel.

Specified by:

distanceMap in interface DistanceTransform3D

Parameters:

image - a 3D binary image with white pixels (255) as foreground

Returns:

a new 3D image containing:

• 0 for each background pixel
• the distance to the nearest background pixel otherwise
