    The organisation of personal data is receiving increasing research attention due to the challenges we face in gathering, enriching, searching, and visualising such data. Given the increasing ease with which personal data ...
  • Multiresolution hierarchy co-clustering for semantic segmentation in sequences with small variations 

    Varas González, David; Alfaro Vendrell, Mónica; Marqués Acosta, Fernando (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    This paper presents a co-clustering technique that, given a collection of images and their hierarchies, clusters nodes from these hierarchies to obtain a coherent multiresolution representation of the image collection. We ...
  • Where is my phone?: personal object retrieval from egocentric images

    Recent research in piecewise linear regression for Super-Resolution has shown the positive impact of training regressors with densely populated clusters whose datapoints are tight in the Euclidean space. In this paper we ...
  • Fast super-resolution via dense local training and inverse regressor search 

    Pérez Pellitero, Eduardo; Salvador, Jordi; Torres Xirau, Iban; Ruiz Hidalgo, Javier; Rosenhahn, Bodo (Springer, 2014)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Regression-based Super-Resolution (SR) addresses the upscaling problem by learning a mapping function (i.e. regressor) from the low-resolution to the high-resolution manifold. Under the locally linear assumption, this ...
  • LEMoRe: A lifelog engine for moments retrieval at the NTCIR-lifelog LSAT task
