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.
