Unified direct visual tracking of rigid and deformable surfaces under generic illumination changes in grayscale and color images

G Silveira, E Malis - International journal of computer vision, 2010 - Springer
The fundamental task of visual tracking is considered in this work as an incremental direct
image registration problem. Direct methods refer to those that exploit the pixel intensities …

Adaptive visual servo control to simultaneously stabilize image and pose error

NR Gans, G Hu, J Shen, Y Zhang, WE Dixon - Mechatronics, 2012 - Elsevier
A novel, Lyapunov-based visual servo controller is presented that stabilizes both the entire
image and pose error vectors simultaneously, rather than a subset of the errors …

Decoupled intensity-based nonmetric visual servo control

G Silveira, L Mirisola, P Morin - IEEE Transactions on Control …, 2018 - ieeexplore.ieee.org
This brief addresses the problem of vision-based robot control where the equilibrium state is
defined via a goal image. Specifically, we consider the class of intensity-based nonmetric …

On intensity-based nonmetric visual servoing

G Silveira - IEEE Transactions on Robotics, 2014 - ieeexplore.ieee.org
This paper considers the problem of vision-based robot stabilization where the equilibrium
state is defined via a reference image. Differently from most solutions, this study directly …

Visual servoing from robust direct color image registration

G Silveira, E Malis - 2009 IEEE/RSJ International Conference …, 2009 - ieeexplore.ieee.org
To date, there exist only few works on the use of color images for visual servoing. Perhaps,
this is due to the difficulties usually found to cope with illumination changes in these images …

The efficient E-3D visual servoing

G Silveira, E Malis, P Rives - International Journal of …, 2008 - Taylor & Francis
A vision-based control technique is proposed to automatically drive a robot to a given
desired pose which has never been reached beforehand. Hence, the corresponding desired …
