Threading fundamental matrices
Shai Avidan, Amnon Shashua · IEEE Transactions on Pattern Analysis and Machine Intelligence · 2001
We present a new function that operates on fundamental matrices across a sequence of views. The operation, we call "threading", connects two consecutive fundamental matrices using the trifocal tensor as the connecting thread. The threading operation guarantees that consecutive camera matrices are consistent with a unique 3D model, without ever recovering a 3D model. Applications include recovery of camera ego-motion from a sequence of views, image stabilization across a sequence, and multi-view image based rendering.
