[Insight-users] Scale estimation of "fuzzy connected image segmentation"(qiuling)

[Ying Zhuge]

Hi:

1) )| B[k](c)-B[k-1](c) | means the number of spels (volume of) B[k](c)
- B[k-1](c). Please see CVIU paper, 145-174 (2000)
2) given the input image, Compute_Scale() in
itkvectorfuzzyconnectedfilter.txx compute the scale vale of each spel in
the image and Compute_Affinity() to compute the affinity of all pairs of
the whole image.

Hope these help.
