PSET is a software package for evaluating page
segmentation algorithms. It has two major functions:
automatically training page segmentation algorithms
on a given training dataset, and testing page
segmentation algorithms on a given test dataset.

Three research page segmentation algorithm are included
in the package. We implemented the X-Y cut algorithm by Nagy and
the Docstrum algorithm by O'Gorman. Professor Kise
provided us his implementation of Voronoi-based algorithm.

We also implemented the Textline-based benchmark algorithm
for error counting and scoring and the Simplex-based
optimization algorithm for automatically select a set
of optimal page segmentation algorithm parameter values.

The version of the DAFS library used in the PSET package is
Release 1.0alpha0. The version of the TIFF library is
v3.0. These libraries are included in the PSET package. They
can be downloaded from
"ftp://ftp.cfar.umd.edu/pub/contrib/sources/illuminator/illuminator-vers".

The directory structure of the PSET package is described as follows:
	- \bin		keeps all executables
	- \dafs 	keeps DAFS library and TIFF library files
	- \doc  	keeps all documentations of the PSET package
	- \experiments	keeps experiments related files
	- \include 	keeps the PSET header file
	- \lib		keeps the PSET library 
	- \samples 	keeps several sample application of the PSET API
	- \src  	keeps all PSET source code
	- \tools	keeps five tools generated using the PSET API

Please read the README file under each directory for detailed package 
information, also go to doc directory for related documentations.
and publications.
