Method Details
- 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
