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.

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.
