SYNOPSIS

10       pfstmo_durand02 [--sigma-s <val>]  [--sigma-r  <val>]  [--base-contrast
11       <val>] [--quiet] [--verbose] [--help]

DESCRIPTION

14       This command implements a tone mapping operator as described in:
15              F. Durand and J. Dorsey.
16              Fast  Bilateral  Filtering for the Display of High-Dynamic-Range
17              Images.
18              In: In ACM Transactions on Graphics, 2002.

20       According to paper, results of this TMO require gamma correction.
21
22       Unless -g option is specified, this operator also employs color correc‐
23       tion mechanism from:
24              Radoslaw Mantiuk, Rafal Mantiuk, Anna Tomaszewska, Wolfgang Hei‐
25              drich.
26              Color Correction for Tone Mapping.

OPTIONS

32       --sigma-s <val>, -s <val>
33              Sigma value for spatial kernel. Default value: 40
34
35       --sigma-r <val>, -r<val>
36              Sigma value for range kernel. Default value: 0.4
37
38       --base-contrast <val>, -c <val>
39              Contrast  of  the base layer. Default value is 5.0f. Lower value
40              causes higher contrast compression and results in darker picture
41              -  can  help  if after tone mapping too many pixels remain satu‐
42              rated.
43
44              Increasing  this  value  will  results  in  brighter  and   more
45              'dynamic' picture.
46
47       --original, -g
48              Use  original algorithm as described in the paper with no exten‐
49              sions. For this operator the switch will disable  color  correc‐
50              tion.
51
52       --verbose
53              Print additional information during program execution.
54
55       --quiet, -q
56              Do not display progress report.
57
58       --help, -h
59              Print list of commandline options.
