Audio-based nonlinear video diffusion
We propose a novel non-linear video diffusion approach which is able to focus on parts of a video sequence that are relevant for applications in audio-visual analysis. The diffusi...

Robust trajectory tracking for a reversing tractor trailer
Tractor-trailer reversing is a classical non-linear control problem in which many of the solutions proposed in the literature perform poorly in the presence of real-world constrai...

Noise filtering method for color images based on LDA and nonlinear diffusion
The purpose of noise filtering for images is to preserve features such as edge or corners in images, while reducing noise. Recent noise filtering algorithms based on diffusion e...

Local feedback passivation of nonlinear discrete-time systems through the speed-gradient algorithm
This paper proposes a method in order to render passive discrete-time nonlinear multiple-input multiple-output (MIMO) systems which are affine in control. The methodology is base...

Dynamics morphing from regulator to oscillator on bipedal control
— A stable non-linear oscillator for autonomous biped stepping control is designed in a top-down manner by morphing dynamics of standing regulator. It resolves three problems whi...
