[Insight-users] Homogeneity matrix in VectorFuzzyConnectednessImageFilter

[Ying Zhuge]

Hi,

The homogeneity-based matrix can be estimated from the sample regions or 
from the whole image. Please see paper "Vectorial scale-based fuzzy 
connectedness image segmentation" in Proc. SPIE:Medical Imaging, vol. 
4684, pp. 1476-1487, 2002.
