Exploiting polar symmetry in designing equivariant observers for vision-based motion estimation
Tarek Bouazza, Robert Mahony, Tarek Hamel
Accurately estimating camera motion from image sequences poses a significant challenge in computer vision and robotics. Many computer vision methods first compute the essential mat…
State Estimation for Linear Systems with Quadratic Outputs
Soulaimane Berkane, Dionysis Theodosis, Tarek Hamel +1
This letter deals with the problem of state estimation for a class of systems involving linear dynamics with multiple quadratic output measurements. We propose a systematic approac…
Constructive barrier feedback for collision avoidance in leader-follower formation control
Zhiqi Tang, Rita Cunha, Tarek Hamel +1
This paper proposes a novel constructive barrier feedback for reactive collision avoidance between two agents. It incorporates this feature in a formation tracking control strategy…
Equivariant Filter (EqF)
Pieter van Goor, Tarek Hamel, Robert Mahony
The kinematics of many systems encountered in robotics, mechatronics, and avionics are naturally posed on homogeneous spaces; that is, their state lies in a smooth manifold equippe…
