QuadSync recovers n cameras from quadrifocal tensors by showing the block tensor admits a Tucker decomposition of multilinear rank (4,4,4,4) independent of n and solving it with ADMM and IRLS, while also enabling joint synchronization with trifocal and bifocal tensors.

QuadSync: Quadrifocal Tensor Synchronization via Tucker Decomposition
QuadSync recovers n cameras from quadrifocal tensors by showing the block tensor admits a Tucker decomposition of multilinear rank (4,4,4,4) independent of n and solving it with ADMM and IRLS, while also enabling joint synchronization with trifocal and bifocal tensors.
