    • Activities of daily living monitoring via a wearable camera: toward real-world applications 

      Cartas Ayala, Alejandro; Radeva, Petia; Dimiccoli, Mariella (Institute of Electrical and Electronics Engineers (IEEE), 2020)
      Article
      Open Access
      Activity recognition from wearable photo-cameras is crucial for lifestyle characterization and health monitoring. However, to enable its wide-spreading use in real-world applications, a high level of generalization needs ...
    • Behavioural and neurophysiological signatures in the retrieval of individual memories of recent and remote real-life routine episodic events 

      Nicolás, Berta; Wu, Xiongbo; Garcia-Arch, Josué; Dimiccoli, Mariella; Sierpowska, Joanna; Saiz-Masvidal, Cristina; Soriano Mas, Carles; Radeva, Petia; Fuentemilla, Lluís (2021-08)
      Article
      Open Access
      Autobiographical memory (AM) has been largely investigated as the ability to recollect specific events that belong to an individual's past. However, how we retrieve real-life routine episodes and how the retrieval of these ...
    • Enhancing temporal segmentation by nonlocal self-similarity 

      Dimiccoli, Mariella; Wendt, Herwig (2019)
      Conference report
      Open Access
      Temporal segmentation of untrimmed videos and photo-streams is currently an active area of research in computer vision and image processing. This paper proposes a new approach to improve the temporal segmentation of ...
    • Introduction to the special issue: egocentric vision and lifelogging 

      Dimiccoli, Mariella; Gurrin, Cathal; Crandall, David; Giró Nieto, Xavier; Radeva, Petia (2018-06-15)

    • Learning event representations for temporal segmentation of image sequences by dynamic graph embedding 

      Dimiccoli, Mariella; Wendt, Herwig (2021)
      Article
      Open Access
      Recently, self-supervised learning has proved to be effective to learn representations of events suitable for temporal segmentation in image sequences, where events are understood as sets of temporally adjacent images that ...
    • LEMoRe: A lifelog engine for moments retrieval at the NTCIR-lifelog LSAT task 

      de Oliveira Barra, Gabriel; Cartas Ayala, Alejandro; Bolaños, Marc; Dimiccoli, Mariella; Giró Nieto, Xavier; Radeva, Petia (2016)
      Conference lecture
      Open Access
      Semantic image retrieval from large amounts of egocentric visual data requires to leverage powerful techniques for filling in the semantic gap. This paper introduces LEMoRe, a Lifelog Engine for Moments Retrieval, developed ...
    • Modeling long-term interactions to enhance action recognition 

      Cartas Ayala, Alejandro; Radeva, Petia; Dimiccoli, Mariella (Institute of Electrical and Electronics Engineers (IEEE), 2021)
      Conference report
      Open Access
      In this paper, we propose a new approach to understand actions in egocentric videos that exploits the semantics of object interactions at both frame and temporal levels. At the frame level, we use a region-based approach ...
    • Neighborhood filters and the recovery of 3D information 

      Digne, Julie; Dimiccoli, Mariella; Salembier Clairon, Philippe Jean; Sabater, Neus (2011)
      Part of book or chapter of book
      Restricted access - publisher's policy
      Following their success in image processing (see Chap. 26), neighborhood filters have been extended to 3D surface processing. This adaptation is not straightforward. It has led to several variants for surfaces depending ...
    • Neighborhood filters and the recovery of 3D information 

      Digne, Julie; Dimiccoli, Mariella; Sabater, Neus; Salembier Clairon, Philippe Jean (2015-09-01)

    • Seeing and hearing egocentric actions: how much can we learn? 

      Cartas Ayala, Alejandro; Luque, Jordi; Radeva, Petia; Segura, Carlos; Dimiccoli, Mariella (2019)
      Conference report
      Open Access
      Our interaction with the world is an inherently multi-modal experience. However, the understanding of human-to-object interactions has historically been addressed focusing on a single modality. In particular, a limited ...
    • Semantic summarization of egocentric photo stream events 

      Lidon, Aniol; Bolaños, Marc; Dimiccoli, Mariella; Radeva, Petia; Garolera Freixa, Maite; Giró Nieto, Xavier (2017)
      Conference report
      Restricted access - publisher's policy
      With the rapid increase of users of wearable cameras in recent years and of the amount of data they produce, there is a strong need for automatic retrieval and summarization techniques. This work addresses the problem of ...
    • Smartphone picture organization: a hierarchical approach 

      Lonn, Stefan; Radeva, Petia; Dimiccoli, Mariella (2019-10-01)
      Article
