NAME

       pfstmo_reinhard02 - Photographic Tone Reproduction for Digital Images

SYNOPSIS

       pfstmo_reinhard02  [--scales] [--key <val>] [--phi <val>] [--range <val>] [--lower <val>] [--upper <val>] [--temporal-coherent] [--verbose]
       [--help]

DESCRIPTION

       This command implements a tone mapping operator as described in:

       Photographic Tone Reproduction for Digital Images.  E. Reinhard, M. Stark, P. Shirley, and J. Ferwerda.	In ACM Transactions  on  Graphics,
       2002.

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

OPTIONS

       [--scales]

	      Use scales to calculate local adaptation. That means: use local version of this operator. By default, global version is used.

       [--key <val>]

	      Set key value for the image (refer to paper for details).  Default value: 0.18, accepted range <0..1>.

       [--phi <val>]

	      Set phi value (refer to paper for details).  Default value: 1.0, accepted range >=0.0.

       [--range <val>]

	      Set range size (refer to paper for details).  Default value: 8, accepted range >1.

       [--lower <val>]

	      Set lower scale size (refer to paper for details).  Default value: 1, accepted range >=1.

       [--upper <val>]

	      Set upper scale size (refer to paper for details).  Default value: 43, accepted range >=1.

       [--temporal-coherent], [-t]

	      When  this option is specified, tone mapping is time coherent for video sequences. Currently the option imposes that the average and
	      maximum luminance value can change at most by 1% between two consecutive frames.

       --verbose

	      Print additional information during program execution.

       --help

	      Print list of commandline options.

EXAMPLES

       pfsin memorial.hdr | pfstmo_reinhard02 -s | pfsout memorial.png

	      Tone map image and save it in png format.

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 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 correction mechanism from:
	      Radoslaw Mantiuk, Rafal Mantiuk, Anna Tomaszewska, Wolfgang Heidrich.
	      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 memorial.png
	      Tone map image and save it in png format.
