1. A system for compound object separation, comprising: a compound object splitter component configured to generate, from a representation of a potential compound object, a first representation of a first potential sub-object and a second representation of a second potential sub-object by eroding a first set of voxels from the representation of the potential compound object; and a volume reconstructor component configured to generate a first image representing the first potential sub-object from the first representation and a second image representing the second potential sub-object from the second representation, the volume reconstructor component comprising: a neighboring eroded voxel identifier component configured to group one or more voxels, of the first set of voxels, that are spatially connected to the first representation to generate a second set of voxels; and an eroded voxel dissolver component configured to dissolve the second set of voxels to generate at least a first portion of the first image.
