5. Observing figures 2c and 2f, the neighbourhood prior
successively erodes small areas improving the
smoothness of the DT image, and hence the distance
that a boundary may travel.
The use of the approach would have merit where comment 2
above is satisfied.
Figure 1: a) Original boundary B; b) Latent variable p(B’),
iteration 1; c) Distance transform (DT) of class label boundaries,
iteration 1. This defines the topographic surface used for boundary
movement; d) Boundary (B) at start of iteration 2; e) Latent
variable p(B’), iteration 2; f) Distance transform of class label
boundaries, iteration 2. This defines the topographic surface used
for boundary movement.
