• Exploring the best classification from average feature combination 

      Hou, Jian; Liu, Wei-Xue; Karimi, Hamid Reza (Peer reviewed, 2014)
      Feature combination is a powerful approach to improve object classification performance. While various combination algorithms have been proposed, average combination is almost always selected as the baseline algorithm to ...
    • Research on vocabulary sizes and codebook universality 

      Liu, Wei-Xue; Hou, Jian; Karimi, Hamid Reza (Journal article; Peer reviewed, 2014)
      Codebook is an effective image representation method. By clustering in local image descriptors, a codebook is shown to be a distinctive image feature and widely applied in object classification. In almost all existing works ...
