ENH: Clamp STAPLEImageFilter maximum iterations

jhlegarreta · dzenanz · commit a7546b667d70 · 2022-09-26T09:22:11.000-04:00
Clamp `STAPLEImageFilter` maximum iterations to avoid setting a 0 value, and thus giving rise dynamic memory defects when querying about non-existing vector indices for the sensitivity and specifity. Related to commit 5b5d85e.
