Square-Root Cubature Information Hybrid Consensus Filter With Correlated Noise and Its Applications in Camera Networks

open access: yesIEEE Access, 2019
This paper proposes a hybrid consensus-based square-root cubature information filter for target tracking in camera networks in the case that the process and measurement noises are correlated with each other at the same time. To the best of our knowledge,
