PHACT: parallel HOG and correlation tracking [PDF]

open access: yes, 2014
Histogram of Oriented Gradients (HOG) based methods for the detection of humans have become one of the most reliable methods of detecting pedestrians with a single passive imaging camera. However, they are not 100 percent reliable. This paper presents an

Online Correction Method for Ratio Methods by Using Geomagnetic Sensors Based on Kalman Filter

open access: yesIEEE Access, 2019
By eliminating the data offset caused by a disturbing magnetic field during the flying condition of a spinning projectile, an adaptive unscented Kalman filter is applied to estimate the actual data of a geomagnetic field and the false value introduced by

Adaptive pose and inertial parameters estimation of free-floating tumbling space objects using dual vector quaternions

open access: yesAdvances in Mechanical Engineering, 2017
The robust parameter estimation of unknown space objects is essential to the on-orbit servicing missions. Based on the adaptive filtering techniques along with the dual quaternions modeling methods for pose estimation, this article proposes a dual vector

Ensemble Kalman filtering with residual nudging: an extension to state estimation problems with nonlinear observation operators [PDF]

open access: yes, 2014
The ensemble Kalman filter (EnKF) is an efficient algorithm for many data assimilation problems. In certain circumstances, however, divergence of the EnKF might be spotted.

Covariance inflation in the ensemble Kalman filter: a residual nudging perspective and some implications [PDF]

open access: yes, 2013
This note examines the influence of covariance inflation on the distance between the measured observation and the simulated (or predicted) observation with respect to the state estimate. In order for the aforementioned distance to be bounded in a certain

Considering spatiotemporal evolutionary information in dynamic multi‐objective optimisation

open access: yesCAAI Transactions on Intelligence Technology, EarlyView., 2023
Abstract Preserving population diversity and providing knowledge, which are two core tasks in the dynamic multi‐objective optimisation (DMO), are challenging since the sampling space is time‐ and space‐varying. Therefore, the spatiotemporal property of evolutionary information needs to be considered in the DMO.

Precise Train Positioning With Unscented Kalman Filter and Low-Cost Sensors

open access: yesIEEE Open Journal of Intelligent Transportation Systems
This contribution is embedded into the challenge of track fault localization with low-cost hardware. For precise localization on the track, with an accuracy of a few decimeters for separating overlapping errors, a high resolution trajectory is needed and
