Changes from beta to version 1.0
                     ================================

Listed below are the major changes which have been made from the beta
version to version 1.0.  I have listed only those changes which affect
the framework and its operation.  Other minor changes have occured but
do not significantly alter the framework.

1. Added the suffix .ts to all test suite directories in the imgs
subdirectory.  This allows valid test suites to be easily
distinguished from documentation or anciliary files and directories.
To update the test suite directories from Beta version to version 1.0,
simply append the suffix .ts to existing test suite directory names.

Scripts/programs affected:
           bin/collateResults
           bin/genAlgHTML
           bin/runalg
           bin/runscore
           bin/runtest
           bin/runtype
           imgs/_artBrick/buildBombMortar
           imgs/_artBrickL/buildLattice

2.  Added the suffix .alg to all algorithm result directories in the
algs subdirectory.  This allows valid algorithm directories to be
easily distinguished from documentation or anciliary files and
directories.  To retain existing results from Beta version, append
.alg to all algorithm result directories in MEASTEX_ROOT/algs.  Also,
for each algorithm directory, append .ts to all test suite
subdirectory names.

Scripts/programs affected:
           bin/cleanalg
           bin/collateResults
           bin/genAlgHTML
           bin/genResHTML
           bin/processAllScores
           bin/runalg
           bin/runscore
           bin/runtest
           bin/runtype

3. Added three environment variables (MEASTEX_ROOT, MEASTEX_ALGS and
MEASTEX_IMGS) to allow more flexibility when running tests.  When
MEASTEX_ROOT is set, the user no longer needs to be in the top-level
directory to run any of the scripts.  Also, the MEASTEX_ALGS and
MEASTEX_IMGS environment variables allow multiple users to access the
framework, saving their own results in a private algorithm directory
and accessing individual test suites.  The MEASTEX_IMGS directory may
just be a directory with links to a subset of the global test suites.
See http:www/for_using.html for usage information.

Scripts/programs affected:
           bin/cleanalg
           bin/collateResults
           bin/genAlgHTML
           bin/genResHTML
           bin/processAllScores
           bin/processScores
           bin/runalg
           bin/runscore
           bin/runtest
           bin/runtype


4. Modified performance metric to add normalization option.  Scores
can now be normalized with respect to the probabilistic prior
probabability score or normalized with respect to the binary
(winner-take-all) prior probability score.  The score can also be left
un-normalized.  This option must also be handled by runscore,
processScores and processAllScores.

Scripts/programs affected:
           bin/scoretest
           bin/runscore
           bin/processScores
           bin/processAllScores
           src/general/scoretest.c

5. Distribution method for visTex and newTex test suites have been
changed to reduce size of distribution.  The original images are no
longer distributed, just instructions on where and how to obtain the
full image files, the .Test and .Valid files, and scripts to extract
the subimages.

6. The operation to make the GLCM symmetric did not correctly handle
the diagonal elements.  This bug has been fixed.  

NOTE: If you obtained results using the beta version of this
algorithm, then they will be invalid.  The bug has a reasonably minor
effect on the results but an improvement is generally achieved with
the correct implementation.

Scripts/programs affected:
           src/glcm/glcmClass.c

7. The set of standard Nth order symmetric masks (N = 1,7) have been
added as optional masks for the Gaussian Markov Random Fields
algorithm.

Scripts/programs affected:
           src/markov/markovClass.c, markovClass.h

8. Addition feature set options were added to the GLCM algorithm.
Three commonly used glcm feature sets were implemented.

Scripts/programs affected:
           src/glcm/glcmClass.c

9. A new test suite, demo.ts has been added to test the installation.

10. A second classifier (K-Nearest Neighbour) has been added to all
algorithms to complement the multivariate Gaussian Bayesian classifier

Scripts/programs affected:
           src/glcm/glcmClass.c, glcmClass.h
           src/gabor/gaborClass.c, gaborClass.h
           src/markov/markovClass.c, markovClass.h
           src/lib/Makefile
           src/lib/KNNClass.c
           src/lib/MVGClass.c
           src/lib/MeasTex.h

11. A new algorithm, fractalClass, has been added which implements a
classifier using features based on Fractal Dimension of an image.

Scripts/programs affected:
           src/fractal/fractalClass.c, fractalClass.h, Makefile
           src/Makefile
