1. A method for analyzing a reconstructed charged particle image of a volume from charged particle detector measurements to detect objects within the volume, the method comprising: partitioning the reconstructed charged particle image of the volume into a set of voxels wherein each voxel is associated with an intensity value; identifying a subset of the set of voxels as object-candidate voxels for generating objects by performing a segmentation operation on the reconstructed charged particle image of the volume; and identifying one or more objects within the reconstructed charged particle image of the volume by performing a connected-component analysis on the object-candidate voxels.
