[Insight-users] A challenge in semi-automatic segmentation

[David Sarrut]

Hello,

you can try to use vv http://www.creatis.insa-lyon.fr/rio/vv/ that allows to
vizualize images and save a list of landmarks that have been selected by
hitting the space key. The list of points is saved in a simple  text ascii
file that you can read with you program.
