23/02/2009 PFSTMO 1.4
* mantiuk08: added color correction method from (http://zgk.wi.ps.pl/color_correction/)
* mantiuk08: fixed dependency on libgsl (thanks to Niels)
* durand02: added color correction method from (http://zgk.wi.ps.pl/color_correction/)
04/11/2008
* all: variables with underscore replaced with "n<variable name>"
as they caused compilation problems under cygwin
21/09/2008
* mantiuk08: Refactored for exception safety
21/09/2008
* build: Removed bogus flag -march=nocona; added CPU detection and
--disable-portable option for enabling non-portable optimizations.
Tunes for local CPU by default, can be disabled using
--without-gcc-arch
21/09/2008
* pfstmo.h: Templatized Array2D; added copy constructor,
assignment operator, and function `allocate' for re-initializing
array after construction
09/09/2008 PFSTMO 1.3.2
* durand02: removed downsampling option - introduced large errors
into the results
08/09/2008
* durand02: division by zero bug fixed (fastbilateral)
* durand02: range boundary bug fixed (fastbilateral)
* durand02: added progress reporting (fastbilateral)
* durand02: performance imrovements in fastbilateral
* mantiuk08: found the cause for the uninitialized value in the cqpminimizer.
Initialization moved to more a suitable code location
05/09/2008
* durand02: disabled fast_bilateral after finding some bugs. A
slow bilateral filter will be used until bugs are fixed.
04/09/2008
* all: removed dependency on pfs::Array2D[Impl], replaced by new
class pfstmo::Array2D. Apart from getting rid of the dependency,
this also speeds thing up considerably because pfstmo::Array2D is
non-virtual and thus can be inlined.
03/09/2008
* durand02: added missing delete in fastBilateralFilter. All TMOs
are now valgrind memcheck-clean.
03/09/2008
* mantiuk08: fixed uninitialized value in gsl_cqpminimizer_alloc.
02/09/2008
* fattal02: replaced delete with correct delete[] operators in PDE
solver.
27/08/2008
* fixed: added missing FFTW3F_CFLAGS for durand02 operator
* pattanaik00: Fixed a bug that would cause every frame to be
treated as the first frame, never invoking
VisualAdaptationModel::calculateAdaptation.
27/08/2008
* configure.ac: Added missing likely/unlikely macros
26/08/2008 PFSTMO 1.3.1
* mantiuk06: Ed Brambley's bug-fix and convergence patch:
- There was a bug in the upsampling code that could cause an
out-of- bound read past the end of allocated memory. This was
occasionally causing NaNs to creep in, at least in a few runs I
did. This has been fixed.
- The patch adds some code to monitor how we're converging to a
solution, and to reset the iteration if necessary. In the few
examples I've tried, this has made the convergence much more
robust.
- The patch changes the start point of the iteration. Before, we
started from a uniform gray ("x" was initialized to 0.0f
everywhere). Now, we start from the original image. I found
this also helps the iteration be more robust, although
sometimes its quicker and sometimes its slower this way.
- The clipping prevention code has been modified to be scale
independent. A badly-scaled input file should no longer cause
a loss of dynamic range.
Overall, the code runs sometimes a little more slowly and
sometimes about the same speed as before, although it is, I
believe, now far more robust and much more likely to converge.

* mantiuk06: Ed Brambley's OpenMP patch:
I've attached a second patch (which depends on the first one).
This patch is a first attempt at parallelizing the code to run on
OpenMP. I've tried to avoid assuming how many processors there
will be, so it should scale to 4 or 8 processors quite happily.
I'll let you know when I get my Quad core set up :-)
There are probably more efficient ways to parallelize the code;
for example, having only one or two "#pragma omp parallel"
sections and lots of "#pragma omp for" or "#pragma omp sections"
sections, but I've not tried to do this. It happily uses 100% of
both cores on the dual-core box I tried it on, and gives knocks
about 20 seconds of a typical 1 minute tone mapping.
* mantiuk06: fixed references to exp10f (missing in some compilers)
* mantiuk06: added branch prediction optimizations (thanks to Lebed Dmytry)
* mantiuk08: better handling of zero-values in HDR images - previously it could fail on some images
* mantiuk08: removed some debug code
* mantiuk08: added branch prediction optimizations
* added: autoconf checks for OpenMP and some gcc optimization options
16/06/2008 PFSTMO 1.3
* added: mantiuk08 - display adaptive tone mapping
* mantiuk06: updated documentation, added --quiet option,
can now process more than one image in a loop
19/02/2008 PFSTMO 1.2
* mantiuk06: fixed some serious bugs in the solver and subsampling
procedure the artifacts found in some odd-sized images
should be gone
* mantiuk06: faster up-/down-sampling functions make the
algorithm 25% faster. Thanks to Ed Brambley.
* mantiuk06: performance improvements from Ed Brambley: lower
memory consumption, faster solver, better convergence,
additional scale parameter for the contrast equalization
method.
11/07/2007 PFSTMO 1.1
* pfstmo-1.1: first release on sourceforge
* small fixes with parameters (Miguel Granados)
* reinhard05: renamed from reinhard04 to correct publication year.
substantial corrections to the code

added noise level parameter (Przemyslaw Bazarnik),
manpage updates - explanation of parameters
* mantiuk06: new gradient domain operator
implementation by Radoslaw Mantiuk
* ashikhmin02: implementation temporarily dropped
imposible to reproduce results from paper
05/12/2005

29/11/2005
* fixed ansi compatibilities (fattal02)
14/12/2004
* new algorithms
ashikhmin02, fattal02
* durand02
corrected interpretation of compression factor
percentile to estimate min and max in final mapping -> more stable
* pattanaik02
