    • Identification of damaged wheat kernels and cracked-shell hazelnuts with impact acoustics time-frequency patterns 

      Ince, N. F.; Onaran, I.; Pearson, T.; Tewfik, A. H.; Çetin, A. Enis; Kalkan, H.; Yardimci, Y. (American Society of Agricultural and Biological Engineers, 2008)
      A new adaptive time-frequency (t-f) analysis and classification procedure is applied to impact acoustic signals for detecting hazelnuts with cracked shells and three types of damaged wheat kernels. Kernels were dropped ...
    • Subset selection with structured dictionaries in classification 

      İnce, N. F.; Göksu, F.; Tewfik, A. H.; Onaran, İbrahim; Çetin, A. Enis (EURASIP, 2007)
      This paper describes a new approach for the selection of discriminant time-frequency features for classification. Unlike previous approaches that use the individual discrimination power of expansion coefficients, the ...
