    • Comparing samples from the 𝒢0 distribution using a geodesic distance 

      Frery, Alejandro C.; Gambini, Juliana (2019)
      "The 𝒢0 distribution is widely used for monopolarized SAR image modeling because it can characterize regions with different degrees of texture accurately. It is indexed by three parameters: the number of looks (which can ...
    • Estudio sobre la aplicación del método SIFT en imágenes SAR 

      Agopian, Michel; Colloca, Tomás; Di Nucci, Nicolás Santiago (2017)
      "En este trabajo se estudia la aplicación del método SIFT y su variante: el algoritmo SAR-SIFT desarrollado para aplicarse en imágenes SAR. Se introduce primero el motivo de interés del uso de este tipo de imágenes, ...
    • The geodesic distance between 𝒢I0 models and its application to region discrimination 

      Naranjo-Torres, José; Gambini, Juliana; Frery, Alejandro C. (2017-03)
      "The 𝒢I0 distribution is able to characterize different regions in monopolarized SAR imagery. It is indexed by three parameters: the number of looks (which can be estimated in the whole image), a scale parameter, and a ...
    • Methods and frameworks for sampling 𝒢I0 data 

      Chan, Debora; Rey, Andrea; Gambini, Juliana; Cassetti, Julia; Frery, Alejandro C. (2017-12)
      "The 𝒢I0 distribution is a competitive tool for SAR image description. This distribution is useful for describing speckled imagery because it models adequately areas with different degrees of texture. Data simulation is ...
    • Sampling from the 𝒢I0 distribution 

      Chan, Debora; Rey, Andrea; Gambini, Juliana; Frery, Alejandro C. (2018-12)
      "Synthetic Aperture Radar (SAR) images are widely used in several environmental applications because they provide information which cannot be obtained with other sensors. The 𝒢I0 distribution is an important model for ...
    • SAR Image segmentation based on multifractal features 

      Pacheco, Cristian; Gambini, Juliana; Delrieux, Claudio (2019)
      "Synthetic Aperture Radar (SAR) imaging is based on airborne or satellite active microwave sensors that can capture the earth surface by emitting a signal and receiving the backscattered signal that forms the resulting ...
