Hi, I am implementing some shape features Moran's I index and Geary's C
Measure and it is working fine for digital phantom, config C, D and E
but for config A and B these two features are not matching with IBSI
reference values. When I set voxel spacing as (2,2,2) then these two
feature values are matching with IBSI but in config A, resample is
false then the voxel spacing will be the input voxel spacing (i.e.,
(0.977 0.977 3))  and config B performs 2d resampling, the voxel
spacing will be (2,2,3).

I am not sure whether the issue is from my implementation or IBSI
reference value of these two features. My implementation is working
fine for all configs except A and B. Please let me know your
feedback/comments on it.

HELLO,I would like to know if the results of feature extraction using ITK-SNAP are affected by IBSI

Is the initiative still working?
