Calibration with concurrent PT axes
(2009-02)
Text en actes de congrés.
Accés obert
Text en actes de congrés.
Accés obert
The introduction of active (pan-tilt-zoom or PTZ) cameras in Smart Rooms in addition to fixed static cameras
allows to improve resolution in volumetric reconstruction, adding the capability to track smaller objects ...
Segmentation-based multi-scale edge extraction to measure the persistence of features in unorganized point clouds
(2017)

Text en actes de congrés.
Accés obert
Edge extraction has attracted a lot of attention in computer vision. The accuracy of extracting edges in point clouds can be a significant asset for a variety of engineering scenarios. To address these issues, we propose ...
SLAM-based 3D outdoor reconstructions from lidar data
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Text en actes de congrés.
Accés obert
Text en actes de congrés.
Accés obert
The use of depth (RGBD) cameras to reconstruct large outdoor environments is not feasible due to lighting conditions
and low depth range. LIDAR sensors can be used instead.
Most state of the art SLAM methods are devoted ...

Collaborative voting of 3D features for robust gesture estimation
(Institute of Electrical and Electronics Engineers (IEEE), 2017)
Comunicació de congrés.
Accés obert
Comunicació de congrés.
Accés obert
Human body analysis raises special interest because it enables a wide range of interactive applications. In this paper we present a gesture estimator that discriminates body poses in depth images. A novel collaborative ...
Prediction error image coding using a modified stochastic vector quantization scheme
(IEEE, 1996)
Text en actes de congrés.
Accés obert
Text en actes de congrés.
Accés obert
The 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 ...
Multi-view body tracking with a detector-driven hierarchical particle filter
(Springer, 2012)
Text en actes de congrés.
Accés restringit per política de l'editorial
Text en actes de congrés.
Accés restringit per política de l'editorial
In 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 ...
Representing and retrieving regions using binary partition trees
(Institute of Electrical and Electronics Engineers (IEEE), 1999)
Text en actes de congrés.
Accés obert
Text en actes de congrés.
Accés obert
This paper discusses the interest of Binary Partition Trees for image and region representation in the context of indexing and similarity based retrieval. Binary Partition Trees concentrate in a compact and structured way ...
Multi-resolution illumination compensation for foreground extraction
(2009-11)
Comunicació de congrés.
Accés obert
Comunicació de congrés.
Accés obert
Illumination 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 ...
