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.
