    • A robust stochastic approach to mineral hyperspectral analysis for geometallurgy 
      Egaña, Álvaro F.; Santibáñez Leal, Felipe A.; Vidal, Christian; Díaz, Gonzalo; Liberman, Sergio; Ehrenfeld, Alejandro (MDPI, 2020)
      Most mining companies have registered important amounts of drill core composite spectra using different acquisition equipment and by following diverse protocols. These companies have used classic spectrography based on ...
    • Analysis and Classification of Natural Rock Textures based on New Transform-based Features 
      Lobos, Rodrigo; Silva Sánchez, Jorge; Ortiz Cabrera, Julián; Díaz, Gonzalo; Egaña, Álvaro (2016)
      This work develops a mathematical method to extract relevant information about natural rock textures to address the problem of automatic classification. Classical methods of texture analysis cannot be directly applied in ...
    • Geological Facies Recovery Based on Weighted l(1)-Regularization 
      Calderón, Hernán; Santibáñez, Felipe; Silva Sánchez, Jorge; Ortiz, Julian; Egaña, Álvaro (Springer, 2020)
      A weighted compressed sensing (WCS) algorithm is proposed for the problem of channelizetl facies reconstruction from pixel-based measurements. This strategy integrates information from: (i) image structure in a transform ...
