[Insight-users] auto crop image

[Bradley Lowekamp]

Hello,

Another option would be to use the LabelStatisticsImageFilter to get the bounding box:

http://www.itk.org/Doxygen/html/classitk_1_1LabelStatisticsImageFilter.html#a132a7474536f24a7285950353cfe0e3c

Then combine that with the largest possible region to make the itk::ImageRegion you want. And place that into on of these filters:
