  • A closed-loop approach for tracking a humanoid robot using particle filtering and depth data 

    Martínez González, Pablo Arturo; Lin, Xiao; Castelan, Mario; Casas Pla, Josep Ramon; Arechavaleta, Gustavo (Springer, 2017-05-24)
    Article
    Accés obert
    Humanoid robots introduce instabilities during biped march that complicate the process of estimating their position and orientation along time. Tracking humanoid robots may be useful not only in typical applications such ...
  • Distributed training strategies for a computer vision deep learning algorithm on a distributed GPU cluster 

    Campos, Victor; Sastre, Francesc; Yagües, Maurici; Bellver, Míriam; Giró Nieto, Xavier; Torres Viñals, Jordi (Elsevier, 2017)
    Article
    Accés obert
    Deep learning algorithms base their success on building high learning capacity models with millions of parameters that are tuned in a data-driven fashion. These models are trained by processing millions of examples, so ...
  • Multiscale combinatorial grouping for image segmentation and object proposal generation 

    Pont Tuset, Jordi; Arbelaez, Pablo Andrés; Barron, Jonathan; Marqués Acosta, Fernando; Malik, Jitendra (2017-01-01)
    Article
    Accés obert
    We propose a unified approach for bottom-up hierarchical image segmentation and object proposal generation for recognition, called Multiscale Combinatorial Grouping (MCG). For this purpose, we first develop a fast normalized ...
  • From pixels to sentiment: fine-tuning CNNs for visual sentiment prediction 

    Campos Camunez, Victor; Jou, Brendan; Giró Nieto, Xavier (2017-02-05)
    Article

    Visual multimedia have become an inseparable part of our digital social lives, and they often capture moments tied with deep affections. Automated visual sentiment analysis tools can provide a means of extracting the rich ...
  • Optimum graph cuts for pruning binary partition trees of polarimetric SAR images 

    Salembier Clairon, Philippe Jean; Foucher, Samuel (Institute of Electrical and Electronics Engineers (IEEE), 2016-09-01)
    Article
    Accés obert
    This paper investigates several optimum graph-cut techniques for pruning binary partition trees (BPTs) and their usefulness for the low-level processing of polarimetric synthetic aperture radar (PolSAR) images. BPTs group ...
  • Description schemes for video program, user and devices 

    Salembier Clairon, Philippe Jean; Richard, Qian; O'Connors, N Et Al; Correia, P. (2000-09)
    Article
    Accés restringit per política de l'editorial
    This paper presents a set of description schemes (DS) dealing with video programs, users and devices. Following MPEG-7 terminology, a description of an AV document includes descriptors (termed Ds), which specify the syntax ...
  • Extensive operators in partition lattices for image sequence analysis 

    Garrido Ostermann, Luis; Salembier Clairon, Philippe Jean; García Vizcaíno, David (1998-04)
    Article
    Accés restringit per política de l'editorial
    This paper deals with the class of extensive operators in the lattice of partitions. These operators are merging techniques. They can be used as filtering tools or as segmentation algorithms. In the first case, they are ...
  • Object-based image coding 

    Pardàs Feliu, Montse (1997-03)
    Article
    Accés restringit per política de l'editorial
    Object-based compression methods describe images in terms of a set of regions (a partition), and of some information for each region to be used by the receiver to reconstruct the image (its texture). Different techniques ...
  • Segmentation of video sequences for partition tree generation 

    Pardàs Feliu, Montse; Salembier Clairon, Philippe Jean (1997-07)
    Article
    Accés restringit per política de l'editorial
    In this paper we propose a segmentation structure to generate a partition tree with multiple partition proposals. These multiple partitions are obtained for every image in a hierarchical way, from the coarsest one to the ...
  • Morphological tools for segmentation: connected operators and watersheds 

    Meyer, F; Oliveras Vergés, Albert; Salembier Clairon, Philippe Jean; Vachier, C (1997-08)
    Article
    Accés restringit per política de l'editorial
    The paper makes a survey of the morphological tools which are useful for image simplification and segmentation. It starts presenting the connected filters, which have the unique feature to simplify the images without ...
