The Square-Root Unscented and the Square-Root Cubature Kalman Filters on Manifolds [PDF]

open access: yesSensors
Estimating the state of a system by fusing sensor data is a major prerequisite in many applications. When the state is time-variant, derivatives of the Kalman filter are a popular choice for solving that task.

An O(N²) Square Root Unscented Kalman Filter for Visual Simultaneous Localization and Mapping [PDF]

open access: yesIEEE Transactions on Pattern Analysis and Machine Intelligence, 2009
This paper develops a square root unscented Kalman filter (SRUKF) for performing video-rate visual simultaneous localization and mapping (SLAM) using a single camera. The conventional UKF has been proposed previously for SLAM, improving the handling of nonlinearities compared with the more widely used extended Kalman filter (EKF).
