• closedAccess   ATM-based analysis and recognition of handball team activities 

      Montoliu Colás, Raul; Martín Félez, Raúl; Torres-Sospedra, Joaquín; Rodríguez Pérez, Sergio Elsevier (2015)
      In this paper, a new methodology based on the Author Topic Model (ATM) method is presented to perform team activity recognition and analysis in handball videos. Instead of using players׳ trajectories we just rely on low ...
    • openAccess   Gait recognition from corrupted silhouettes: a robust statistical approach 

      Ortells Lorenzo, Javier; Mollineda, Ramón A.; Mederos, Boris; Martín Félez, Raúl Springer Verlag (2016-07)
      This paper introduces a method based on robust statistics to build reliable gait signatures from averaging silhouette descriptions, mainly when gait sequences are affected by severe and persistent defects. The term robust ...
    • openAccess   Human recognition based on gait poses 

      Martín Félez, Raúl; Mollineda, Ramón A.; Sánchez Garreta, Josep Salvador Springer (2011)
      This paper introduces a new approach for gait analysis based on the Gait Energy Image (GEI). The main idea is to segment the gait cycle into some biomechanical poses, and to compute a particular GEI for eachpose. Pose-based ...
    • openAccess   Melodic track identification in MIDI files considering the imbalanced context 

      Martín Félez, Raúl; Mollineda, Ramón A.; García, Vicente Springer Verlag (Germany) (2009)
      In this paper, the problem of identifying the melodic track of a MIDI file in imbalanced scenarios is addressed. A polyphonic MIDI file is a digital score that consists of a set of tracks where usually only one of them ...
    • openAccess   On the suitability of combining feature selection and resampling to manage data complexity 

      Martín Félez, Raúl; Mollineda, Ramón A. Springer Verlag (2010)
      The effectiveness of a learning task depends on data com- plexity (class overlap, class imbalance, irrelevant features, etc.). When more than one complexity factor appears, two or more preprocessing techniques should be ...
    • closedAccess   Uncooperative gait recognition by learning to rank 

      Martín Félez, Raúl; Xiang, Tao Elsevier (2014)
      Gait is a useful biometric because it can operate from a distance and without subject cooperation. However, it is affected by changes in covariate conditions (carrying, clothing, view angle, etc.). Existing methods suffer ...
