Improvements of Motion Estimation and Coding using Neural Networks

Raz Birman, Yoram Segal, Ofer Hadar, Jenny Benois-Pineau ยท 2020

Inter-Prediction is used effectively in multiple standards, including H.264 and HEVC (also known as H.265). It leverages correlation between blocks of consecutive video frames in order to perform motiโ€ฆ

Sharp images from diffuse beams: factorisation of the discrete delta function

I. D. Svalbe, D. M. Paganin, T. C. Petersen ยท 2019

Discrete delta functions define the limits of attainable spatial resolution for all imaging systems. Here we construct broad, multi-dimensional discrete functions that replicate closely the action of โ€ฆ

The homunculus for proprioception: Toward learning the representation of a humanoid robot's joint space using self-organizing maps

Filipe Gama, Matej Hoffmann ยท 2019

In primate brains, tactile and proprioceptive inputs are relayed to the somatosensory cortex which is known for somatotopic representations, or, "homunculi". Our research centers on understanding the โ€ฆ

A Nitsche-based cut finite element method for the coupling of incompressible fluid flow with poroelasticity

Christoph Ager, Benedikt Schott, Magnus Winter, Wolfgang A. Wall ยท 2018

The focus of this contribution is the numerical treatment of interface coupled problems concerning the interaction of incompressible fluid flow and permeable, elastic structures. The main emphasis is โ€ฆ

Bitstream-Based JPEG Image Encryption with File-Size Preserving

Hiroyuki Kobayashi, Hitoshi Kiya ยท 2018

An encryption scheme of JPEG images in the bitstream domain is proposed. The proposed scheme preserves the JPEG format even after encrypting the images, and the file size of encrypted images is the exโ€ฆ

Random Switching for High Performance DC-DC Power Converters

Jacques Naude, Ivan Hofsajer ยท 2018

Random Pulse Width Modulation (RPWM) has been successfully applied in power electronics for nearly 30 years. The effects of the various possible RPWM strategies on the Power Spectral Density have beenโ€ฆ

Efficient reduction of Kappa models by static inspection of the rule-set

Andreea Beica, Calin Guet, Tatjana Petrov ยท 2015

When designing genetic circuits, the typical primitives used in major existing modelling formalisms are gene interaction graphs, where edges between genes denote either an activation or inhibition relโ€ฆ

Model-order reduction of biochemical reaction networks

Shodhan Rao, Arjan van der Schaft, Karen van Eunen, Barbara M. Bakker, Bayu Jayawardhana ยท 2012

In this paper we propose a model-order reduction method for chemical reaction networks governed by general enzyme kinetics, including the mass-action and Michaelis-Menten kinetics. The model-order redโ€ฆ
