Method Detail

distanceMap

ij.ImageStack distanceMap(ij.ImageStack image)

Computes the distance map from a 3D label image. Distance is computed for each label voxel (with value greater than 0), as the chamfer distance to the nearest voxel with a different value. The other value value can be 0 (the background) or another positive integer value (corresponding to another region).

Parameters:

image - a 3D label map, where integer values correspond to region labels, and 0 value to background.

Returns:

a new 3D image containing:

• 0 for each background voxel
• the distance to the nearest voxel from another region
