Contour and Arrows
he animated figure below shows how contouring is done with a new and improved algorithm in place. The sequence is show in reverse, as the window titles help indicate. Arrows can be put on top of the contour to signal the direction of movement of each landmark point, but arrow can in general add clutter and it may be worth taking a group of several points and study based on these the direction of movement of entire region, then display fewer large arrows.
