Metric learning from poses for temporal clustering of human motion
(2012)
Comunicació de congrés
Accés restringit per política de l'editorialTemporal clustering of human motion into semantically meaningful behaviors is a challenging task. While unsupervised methods do well to some extent, the obtained clusters often lack a semantic interpretation. In this paper, ... -
Microscopic simulation with AIMSUN for the assessment of incident management strategies
(2002)
Text en actes de congrés
Accés obertPRIME (Prediction of Congestion and Incidents in Real Time, for Intelligent Incident Management and Emergency Traffic Management) was a project of the 5ht Framework Program of the European Union which objectives were to ... -
Morphological filter for lossless image subsampling
(IEEE Computer Society, 1994)
Text en actes de congrés
Accés obertWe present a morphological filter for lossless image subsampling for a given downsampling-upsampling strategy. This filter is applied in a multiresolution decomposition and results in a more efficient scheme for image ... -
Morphological interpolation for texture coding
(. S.N., 1995)
Text en actes de congrés
Accés obertIn this paper a new morphological interpolation technique is presented. It is applied to the coding of the smooth (primary) component in a sketch-based image compression approach for very low bit-rates. The interpolation ... -
Morphological operators for image and video compression
(1996-06)
Article
Accés obertThis paper deals with the use of some morphological tools for image and video coding. Mathematical morphology can be considered as a shape-oriented approach to signal processing, and some of its features make it very useful ... -

Multi-camera multi-object voxel-based Monte Carlo 3D tracking strategies
(HINDAWI, 2011-11-23)
Article
Accés obertThis article presents a new approach to the problem of simultaneous tracking of several people in low-resolution sequences from multiple calibrated cameras. Redundancy among cameras is exploited to generate a discrete 3D ... -
Multi-person tracking strategies based on voxel analysis
(2008-06)
Article
Accés restringit per política de l'editorialThis paper presents two approaches to the problem of simultaneous tracking of several people in low resolution sequences from multiple calibrated cameras. Spatial redundancy is exploited to generate a discrete 3D binary ... -
Multi-resolution illumination compensation for foreground extraction
(2009-11)
Comunicació de congrés
Accés obertIllumination changes may lead to false foreground (FG) segmentation and tracking results. Most of the existing FG extraction algorithms obtain a background (BG) estimation from temporal statistical parameters. Such ... -
Multi-view body tracking with a detector-driven hierarchical particle filter
(Springer, 2012)
Text en actes de congrés
Accés restringit per política de l'editorialIn this paper we present a novel approach to markerless human motion capture that robustly integrates body part detections in multiple views. The proposed method fuses cues from multiple views to enhance the propagation ... -
Multi-view video representation based on fast Monte Carlo surface reconstruction
(2013-09)
Article
Accés restringit per política de l'editorialThis paper provides an alternative solution to the costly representation of multi-view video data, which can be used for both rendering and scene analyses. Initially, a new efficient Monte Carlo discrete surface ... -
New approaches to texture coding in segmentation and feature-based image coding schemes

One shot learning for generic instance segmentation in RGBD videos
(Scitepress, 2019)
Text en actes de congrés
Accés obertHand-crafted features employed in classical generic instance segmentation methods have limited discriminative power to distinguish different objects in the scene, while Convolutional Neural Networks (CNNs) based semantic ... -
Oriented radial distribution on depth data: application to the detection of end-effectors

Person tracking
(Springer-Verlag, 2009-05-31)
Capítol de llibre
Accés restringit per política de l'editorialOne of the most basic building blocks for the understanding of human actions and interactions is the accurate detection and tracking of persons in a scene. In constrained scenarios involving at most one subject, or in ... -
Photo-consistent surfaces from a sparse set of viewpoints
(2010)
Comunicació de congrés
Accés restringit per política de l'editorialWe address the problem of reconstructing 3D shapes from color data available in a sparse set of views from all directions of a scene. As an advantage when compared to multiview stereo approaches, our method is able to ... -
Prediction error image coding using a modified stochastic vector quantization scheme
(IEEE, 1996)
Text en actes de congrés
Accés obertThe objective of this paper is to provide an efficient and yet simple method to encode the prediction error image of video sequences, based on a stochastic vector quantization (SVQ) approach that has been modified to cope ... -
