Active spline model (mac)
Active spline model is a new approach for model-based segmentation. It uses centripetal Catmull-Rom spline to draw boundary, and after segmentation, the boundary can be easily edited.
.
In the attached files, we have used active spline model to automatically segment posterior-anterior lung x-ray. Besides, we have provided all the necessary codes to train a model, and used ocular thermography as an example to do that.

In regard to the zip file -
1. Run ‘jdemospline.m’ to compare among types of splines.
2. go to ‘sample > lung > gui’, run ‘lgui.m’ to have a quick experience of the segmentation.
3. The points on the curve can be moved; click to move (not drag) and see the changes in the curve.
4. Watch the demo video at

5.The uploaded zip file contains fewer and smaller images for ‘lgui.m’ in order to reduce the file size. To get more images (and more videos and details), go to the below website to download the attached zip file: http://jenh.co/2014/01/09/active-spline-models/
