    • A Multi-resolution Approximation for Time Series 
      Sánchez, Heider; Bustos Cárdenas, Benjamín (Springer, 2020)
      Time series is a common and well-known way for describing temporal data. However, most of the state-of-the-art techniques for analysing time series have focused on generating a representation for a single level of resolution. ...
    • A sketch-aided retrieval approach for incomplete 3D objects 
      Lengauer, Stefan; Komar, Alexander; Labrada, Arniel; Karl, Stephan; Trinkl, Elisabeth; Preiner, Reinhold; Bustos Cárdenas, Benjamín; Schreck, Tobías (Elsevier, 2020)
      With the growing amount of digital collections of visual CH data being available across different repositories, it becomes increasingly important to provide archaeologists with means to find relations and cross-correspondences ...
    • A survey on frameworks used for robustness analysis on interdependent networks 
      Bachmann Espinoza, Ivana; Bustos Jiménez, Javier; Bustos Cárdenas, Benjamín (Wiley, 2020)
      The analysis of network robustness tackles the problem of studying how a complex network behaves under adverse scenarios, such as failures or attacks. In particular, the analysis of interdependent networks' robustness ...
    • An efficient algorithm for approximated self-similarity joins in metric spaces 
      Ferrada Aliaga, Sebastián; Bustos Cárdenas, Benjamín; Reyes, Nora (Elsevier, 2020)
      Similarity join is a key operation in metric databases. It retrieves all pairs of elements that are similar. Solving such a problem usually requires comparing every pair of objects of the datasets, even when indexing and ...
    • Combining pixel domain and compressed domain index for sketch based image retrieval 
      Fraga Pimentel Filho, Carlos Alberto; Bustos Cárdenas, Benjamín; Araujo de Albuquerque, Arnaldo; Ferzoli Guimaraes, Silvio Jamil (Springer, 2017)
      Sketch-based image retrieval (SBIR) lets one express a precise visual query with simple and widespread means. In the SBIR approaches, the challenge consists in representing the image dataset features in a structure that ...
    • Improving the space cost of k-NN search in metric spaces by using distance estimators 
      Bustos Cárdenas, Benjamín; Navarro, Gonzalo (2009)
      Similarity searching in metric spaces has a vast number of applications in several fields like multimedia databases, text retrieval, computational biology, and pattern recognition. In this context, one of the most important ...
    • Scalable 3D shape retrieval using local features and the signature quadratic form distance 
      Sipiran, Ivan; Lokoc, Jakub; Bustos Cárdenas, Benjamín; Skopal, Tomas (Springer, 2017)
      We present a scalable and unsupervised approach for content-based retrieval on 3D model collections. Our goal is to represent a 3D shape as a set of discriminative local features, which is important to maintain robustness ...
