[Insight-users] updating advection and propagation images in each iteration (levelset segmentation)

[alireza akhundi asl]

Hi Niranjan
  I tried to use your hints but as I undrestand ThresholdSegmentationLevelSetImageFilter uses static functions.
  Thanks a lot for attention.

  Hi there,

I am also trying to do the same. so far I have figured out the following:
1. you can modify the ThresholdSegmentationLevelSetImageFilter and 
ThresholdSegmentationLevelSetFunction or
alternatively you can create the new class from scrach from the parent 
classes of the respective filter.
2.you need to redefine the following virtual functions in you class 
definitions: InitializeIteration() and CalculateSpeedImage()

I dont know how to modify the advection term as I am not using it at all.

hope this helps,

Niranjan.
