Spectral super-resolution for multispectral image based on spectral improvement strategy and spatial preservation strategy Vrije Universiteit Brussel
While hyperspectral (HS) images play a significant role in many applications, they often suffer from issues such as low spatial resolution, low temporal resolution, and some of the acquired spectral bands are either with low signal-to-noise ratio (SNR) or invalid because of the very high-noise level. To address this issue, a spectral super-resolution method is proposed in this paper to recover a high-spectral-resolution HS image from ...
Automatic Depression Analysis using Dynamic Facial Appearance Descriptor and Dirichlet Process Fisher Encoding Vrije Universiteit Brussel
Depression causes mood disorders with noticeable problems in day-to-day activities. Current methods of assessing depression depend almost entirely on clinical interviews or questionnaires. They lack systematic and efficient ways of incorporating behavioral observations that are strong indicators of a psychological disorder. To help clinicians effectively and efficiently diagnose depression severity, automated systems, using objective and ...
The Variable Boundary Layer Sliding Mode Control: A Safe and Performant Control for Compliant Joint Manipulators Vrije Universiteit Brussel
challenging for two reasons. First, the elastic elements of the
compliant actuators can store an important amount of energy
which can be potentially dangerous and needs therefore to
be controlled. Second, the compliance introduces nonlinearities
and uncertainties in the system. In this paper, we propose a
new control scheme, the Variable Boundary layer ...
Reasoning about object capabilities with logical relations and effect parametricity Vrije Universiteit Brussel KU Leuven
Object capabilities are a technique for fine-grained privilegeseparation in programming languages and systems, with importantapplications in security. However, current formal characterisations donot fully capture capability-safety of a programming language and arenot sufficient for verifying typical applications. Usingstate-of-the-art techniques from programming languages research, wedefine a logical relation for a core calculus of JavaScript ...
Continuous Wave Treshold Characteristics of Coupled-Cavity VCSELs: Experiment and Model Vrije Universiteit Brussel
Body Conducted Speech Enhancement by Equalization and Signal Fusion Vrije Universiteit Brussel
MLEM and OSEM deviate from the Cramer-Rao bound at low counts Vrije Universiteit Brussel
Step Length and Velocity Control of A Dynamic Bipedal Walking Robot with Adaptable Compliant Joints Vrije Universiteit Brussel
extends the passive walking by adapting the compliance of the
joints. Natural motions can be chosen in order to obtain a
controllable and energy efficient walking motion. In this paper,
actuators with online adaptable compliance are used based on
the concept of Controlled Passive Walking, to obtain adjustable
step length and velocity during dynamic bipedal ...
