[Tubetk-developers] tubes extraction from binary image

[Stephen Aylward]

Hi,

I recommend

1) Convert the image to a distance map using ITK's Danielsson Distance
measure filter.   This will convert your binary image to an image that is
bright along the center of your binary object

2) Use TubeTK's SegmentTubeUsingMinimalPath (which uses ITK's minimal path
module) to compute the path down the center of your object, given the
distance map and two end points.  You will need to specify the two end
points of the path, but hopefully that will be easy to due if your image
acquisition protocol is somewhat constrained.   The minimal path method
will then return the path that connect those two endpoints along bright
center of your distance map object.

Hope this helps.
