Some Weighted Distance Transforms in Four Dimensions
[chapter]
2000
Lecture Notes in Computer Science
In a digital distance transform, each picture element in the shape (background) has a value measuring the distance to the background (shape). In a weighted distance transform, the distance between two points is defined by path consisting of a number of steps between neighbouring picture elements, where each type of possible step is given a length-value, or a weight. In 4D, using 3×3×3×3 neighbourhoods, there are four different weights. In this paper, optimal real and integer weights are
