A unique time series library in Python that consists of Kalman filters (discrete, extended, and unscented), online ARIMA, and time difference model. Implementation of Data Fusion through (Extended) Kalman-Filter in OpenCV/C++. $\begingroup$ From what I understand about Kalman Filters EKF is better over KF cause it can handle non gaussian distributions and UKF is better when the data is very non linear.So, I thought about using a UKF but then I say that Ardupilot is using a EKF and I figured an EKF is better suited for the problem.
