[Insight-users] Automatic seed point generation

[Luis Ibanez]

Hi OTL,

It is hard to tell without looking at the image...

...and ultrasound are probably the hardest type of image to deal with...

I would think that the chances of this working are rather slim,
but... hey... the trying to do it will be relatively easy,
so it is better just to go for it and do the experiment.

BTW you may find useful to play with your input image and the
application


    InsightApplications/ShapeDetectionLevelSet

(it does require you to build/install FLTK)



  Please let us know what you find,


     Thanks


        Luis
