    Data Set Information:

    The 5473 examples comes from 54 distinct documents. Each observation concerns one block. All attributes are numeric. Data are in a format readable by C4.5.


    Attribute Information:

    height:   integer.         | Height of the block.
      lenght:   integer.     | Length of the block.
      area:     integer.    | Area of the block (height * lenght);
      eccen:    continuous.  | Eccentricity of the block (lenght / height);
      p_black:  continuous.  | Percentage of black pixels within the block (blackpix / area);
      p_and:    continuous.        | Percentage of black pixels after the application of the Run Length Smoothing Algorithm (RLSA) (blackand / area);
      mean_tr:  continuous.      | Mean number of white-black transitions (blackpix / wb_trans);
      blackpix: integer.    | Total number of black pixels in the original bitmap of the block.
      blackand: integer.        | Total number of black pixels in the bitmap of the block after the RLSA.
      wb_trans: integer.          | Number of white-black transitions in the original bitmap of the block.
