pfstmo_durand02(1)	    General Commands Manual	    pfstmo_durand02(1)

NAME
       pfstmo_durand02	-  Fast	bilateral filtering for	the display of HDR im-
       ages

SYNOPSIS
       pfstmo_durand02 [--sigma-s <val>]  [--sigma-r  <val>]  [--base-contrast
       <val>] [--quiet]	[--verbose] [--help]

DESCRIPTION
       This command implements a tone mapping operator as described in:
	      F. Durand	and J. Dorsey.
	      Fast  Bilateral  Filtering for the Display of High-Dynamic-Range
	      Images.
	      In: In ACM Transactions on Graphics, 2002.

       According to paper, results of this TMO require gamma correction.

       Unless -g option	is specified, this operator also employs color correc-
       tion mechanism from:
	      Radoslaw Mantiuk,	Rafal Mantiuk, Anna Tomaszewska, Wolfgang Hei-
	      drich.
	      Color Correction for Tone	Mapping.
	      In: Computer Graphics Forum (Proc. of  EUROGRAPHICS'09),	28(2),
	      2009.
	      http://zgk.wi.ps.pl/color_correction/

OPTIONS
       --sigma-s <val>,	-s <val>
	      Sigma value for spatial kernel. Default value: 40

       --sigma-r <val>,	-r<val>
	      Sigma value for range kernel. Default value: 0.4

       --base-contrast <val>, -c <val>
	      Contrast	of  the	base layer. Default value is 5.0f. Lower value
	      causes higher contrast compression and results in	darker picture
	      -	can help if after tone mapping too many	 pixels	 remain	 satu-
	      rated.

	      Increasing  this	value  will  results in	brighter and more 'dy-
	      namic' picture.

       --original, -g
	      Use original algorithm as	described in the paper with no	exten-
	      sions.  For  this	operator the switch will disable color correc-
	      tion.

       --verbose
	      Print additional information during program execution.

       --quiet,	-q
	      Do not display progress report.

       --help, -h
	      Print list of commandline	options.

EXAMPLES
       pfsin memorial.hdr | pfstmo_durand02 | pfsgamma -g 2.2 |	pfsout memor-
       ial.png
	      Tone map image and save it in png	format.
