[ITK] [ITK-users] Watershed for 3D Image Segmentation - One Seed Point -

[Abdelkhalek Bakkari]

Dear Dr Richard Beare,


I am trying your code source which is published in the insight journal about the " The watershed transform in ITK - discussion and new developments".


I debugged the perf3D and mperf3D. However, in the mperf3D, it needs two input images. Could you please explain for me the way of adopting it for a .mha file ?


Thank you in advance.


Best regards,

The greedy approaches, like MorphologicalWatershedFromMarkers, require 2 seeds. One is the background seed. Sometimes that can be something very simple like the image boundary. The advantage of greedy approaches is that you don't need to specify stopping conditions. The cost is obviously the extra seed. Another advantage is that most  of the methods naturally support lots of independent seeds, if you want them.

Dear ITK users,


I Would like to know if there is an algorithm in ITK that is proposed for a semi-automatic segmentation of three-dimensional images.

One seed location should be chosen like in Region Growing.

Thank you in advance.
