    • 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 ...
    • Automatic space object detection on all-sky images from a synoptic survey synthetic telescope array 
      San Martín, Felipe; Pérez, Claudio; Tapia, Juan E.; Virani, Shahzad; Holzinger, Marcus J. (Elsevier, 2020)
      Detection, classification, and characterization of Space Objects (SOs) are important tasks in many areas of research. Detection of SOs is important in predicting collisions with debris that could become hazards for satellites ...
    • Brain development parameters and intelligence in Chilean high school graduates 
      Ivanovic, Daniza M.; Leiva, Boris P.; Castro, Carmen G.; Olivares, Manuel G.; Jansana, Joan Manuel M.; Castro, Verónica G.; Almagià, Atillo Aldo F.; Toro, Triana D.; Urrutia, María Soledad C.; Miller, Patricio T.; Bosch, Enrique O.; Larraín, Cristián G.; Pérez, Herná (2004)
      The hypothesis that independently of sex, brain volume (BV) and head circumference (HC) are positively and significantly associated with intellectual quotient (IQ) was examined in a sample of 96 high school graduates of ...
    • Improving signal-to-noise in the direct imaging of exoplanets and circumstellar disks with MLOCI 
      Wahhaj, Zahed; Cieza, Lucas; Mawet, Dimitri; Yang, Bin; Canovas, Héctor; Boer, Jozua de; Casassus Montero, Simón; Ménard, Francois; Schreiber, Matthias; Liu, Michael; Biller, Beth; Nielsen, Eric; Hayward, Thomas (EDP Sciences, 2015)
      We present a new algorithm designed to improve the signal-to-noise ratio (S/N) of point and extended source detections around bright stars in direct imaging data. One of our innovations is that we insert simulated point ...
    • Monitoring and controlling saturation zones in heap leach piles using thermal analysis 
      Daud, Omar; Correa Pérez, Mauricio; Estay Cuenca, Humberto; Ruíz del Solar San Martín, Javier (MDPI, 2021)
      This manuscript describes a method that is based on the implementation and setup of a mechatronic system that can recognize and detect, through thermal analysis, the zones where heap leaching piles may become locally ...
    • Optimising adjacent membrane segmentation and parameterisation in multicellular aggregates by piecewise ... 
      Jara Wilde, Jorge; Castro, I.; Lemus, C.G.; Palma, K.; Valdés, F.; Castañeda Zeman, Víctor; Hitschfeld Kahler, Nancy; Concha Nordemann, Miguel Luis; Härtel, Steffen (Wiley, 2020)
      In fluorescence microscopy imaging, the segmentation of adjacent cell membranes within cell aggregates, multicellular samples, tissue, organs, or whole organisms remains a challenging task. The lipid bilayer is a very thin ...
    • Structural characterization of microcin E492 amyloid formation: Identification of the precursors 
      Arranz, Rocío; Mercado, Gabriela; Martín-Benito, Jaime; Giraldo, Rafael; Monasterio Opazo, Octavio; Lagos Mónaco, Rosalba; Valpuesta, José M. (2012)
      Microcin E492 is a low-molecular weight, channel-forming bacteriotoxin that generates amyloid structures. Using electron microscopy and image processing techniques several structural conformations can be observed. Prior ...
