QuadSync: Quadrifocal Tensor Synchronization via Tucker Decomposition

ArXi:2602.22639v2 Announce Type: replace In structure from motion, quadrifocal tensors capture information than their pairwise counterparts (essential matrices), yet they have often been thought of as impractical and only of theoretical interest. In this work, we challenge such beliefs by providing a new framework to recover $n$ cameras from the corresponding collection of quadrifocal tensors.
