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. SEE ALSO

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.

pfsin memorial.hdr | pfstmo_reinhard02 -s | pfsout memorial.png Tone map image and save it in png format. SEE ALSO
