As the title reads, I would like to use bwdistgeodesic by providing a volume and seed locations. Currently, this function returns the distance to the nearest seed location, but no the index. Does anyone know a way to return the nearest seed index?

This could be a good enhancement request. The same is true for graydist.

bwdistgeodesic function does not return nearest index to point. If you want to get index, use bwdist. You can refer to this documentation link for bwdist: https://www.mathworks.com/help/images/ref/bwdist.html

Hello,

Thank you for your answer, but the point of my question is that I would like to know if there is a way to retrieve the index from bwdistgeodesic as I want the geodesic closest point to my source points but still be bounded by the boundaries of my voxels.
