[ITK] Getting a pixel in a labelled region

[Girish, Gavaskar Ruturaj]

Dear all,

If I want to get any random index of a particular label in a labelled binary image, how do I go about it? As an example, let's say have a labelled binary image containing 8 objects labelled 1,2,....,8. I want get the indices of any random pixel with label 5, i.e. any pixel which belongs to the region labelled 5. I tried getting the centroid using LabelGeometryImageFilter, but for objects which are not convex, the centroid may not lie inside the region. Is there any method to get a random pixel index?

Thanks as always & Regards,
Ruturaj
