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.

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.
