Hi, I am trying to use Octrees on ITK, I saw that ITK have an Octree object. However, I can not find the methods of Octree to get the closest points.
My problem is that I have a region of interest composed of several voxels with x,y,z coordinates in a .nrrd image. I want to put several voxels of this image into an octree structure to query the closest distance to my region of interest. I thought to use Octrees similar to VTK object, but I couldn’t find methods to encode my idea. I saw KD-tress but I am not sure if that structure is the same concept that octree.
Thanks in advance.
