pfstmo_durand02(1)	     General Commands Manual	      pfstmo_durand02(1)

NAME
     pfstmo_durand02 - Fast bilateral filtering for the display of HDR images

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 Im-
	    ages.
	    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  correction
     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 saturated.

	    Increasing this value will results in brighter  and  more  'dynamic'
	    picture.

     --original, -g
	    Use original algorithm as described in the paper with no extensions.
	    For this operator the switch will disable color correction.

     --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.
