Method Detail

distanceMap

ij.process.ImageProcessor distanceMap(ij.process.ImageProcessor image)

Computes the distance map from a label image. Distance is computed for each label pixel (with value greater than 0), as the chamfer distance to the nearest pixel 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 label map, where integer values correspond to region labels, and 0 value to background.

Returns:

a new intensity image containing:

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