Dear Mr. Luis,
Thanks for your help in implementing the Fillholes algorithm.
We used confidence connectedImageFilter on your suggestion. We find that =
it is working fine for an image. But when we use a volume of about =
256X256x120 the ouput is not correct and the process is very slow.=20
I feel the problem is with connectivity.
For a slice, identifying 4 /8 connected pixels could be done easily =
using the above filter.
But for a volume, it should identify 6 / 26 connected pixels which I =
feel the class is not able to do.=20
How to specify the connectivity when we use the confidence =
connectedImage filter.
Regards,
Valli
