[vtkusers] Seed landmark on 2D CT image

[Xiaopeng Yang]

Thank you guys very much on the overlay of mask image over the grayscale image. Couple of days ago I raised another question, but so far I haven’t get any reply. Maybe the problem is kind of too easy one? But for me I spent very long time on it still cannot figure it out.

 

If you guys have any good ideas, please let me know.

 

Thanks,

Yang

Dear friends,

 

Greetings!

 

For applying ITK segmentation algorithm, interactive seed picking is needed. Thus the vtkSeedWidget and vtkPointHandleRepresentation2D are used to put landmarks on the 2D CT image. For navigation between different CT image slices, the vtkSliderRepresentation2D is utilized.

 

The problem is that the previous landmarks marked on a previous image slice also appear on the current slice. How to make the previously marked landmarks stay on that image slice only?

 

Any idea would be greatly appreciated!!

 

Best regards,

Yang
