[Insight-users] Segmentation algorithms

[Harvey Cline]

Hi Elena

In segmentation using region growing a threshold that is too low will
connect to unwanted regions; while, if it is too high it does not completely
segment the region of interest. An algorithm to find the best threshold
involves testing the connectivity between the object to be segmented and
other objects that are not wanted. Often this is done by trial and error;
however, it may be coded using a binary search to find the best connection
between regions.
