[Insight-users] RelabelComponentImageFilter and objects analysis

[Jens Eickmeyer]

Hi!

I had to do a similar task. I use a map with the label as key and a
struct as the value. The struct holds all the information which are
interesting for a certain object. I iterate over the label image and
use the corresponding pixel values in the original image to compute
the characteristics of each objects. This is pretty fast.
