NAME

SYNOPSIS

9       pfstmo_pattanaik00  [--time-dependence]  [--fps  <val>]  [--mul <multi‐
10       plier>] [--local] [--cone <val>] [--rod <val>] [--verbose] [--help]

DESCRIPTION

13       This command implements a tone mapping operator as described in:
14
15       Time-Dependent Visual Adaptation for  Realistic  Image  Display.   S.N.
16       Pattanaik,  J.  Tumblin, H. Yee, and D.P. Greenberg.  In Proceedings of
17       ACM SIGGRAPH 2000.
18
19       This operator requires properly calibrated image data  (in  cd/m2)  and
20       its results should be gamma corrected.
21
22       The local version of this operator is based on the following paper:
23
24       Adaptive  Gain Control For High Dynamic Range Image Display.  S.N. Pat‐
25       tanaik, H. Yee.  In proceedings of SCCG 2002.

OPTIONS

29       --time-dependence, -t
30
31              Use time dependent model of adaptation. This should be used  for
32              tone  mapping  of  an  animation. It has no influence on single-
33              frame input. Switched off by default.  Note: it is important  to
34              correctly set the speed of the input animation (--fps).
35
36       --fps <val>, -f <val>
37
38              Speed  of  input animation in frames per second. Used when time-
39              dependence is switched on (-t). Default value: 16.0
40
41       --mul <multiplier>, -m <multiplier>
42
43              Multiply input values by a multiplier value.   Useful  if  input
44              data is not calibrated. Default value: 1.0
45
46       --local, -l
47
48              Use  local  version  of the tone mapping. Time-dependent effects
49              are cancelled while using local version, global version is  used
50              by default.
51
52       --cone <val>, -c <val>
53
54              Set  the  adaptation  level for cones. If --rod parameter is not
55              used, this will also set  the  adaptation  level  for  rods.  By
56              default,  the  adaptation  level  is calculated as a logarithmic
57              average of luminance in the input image.
58
59       --rod <val>, -r <val>
60
61              Set the adaptation level for rods. By  default,  the  adaptation
62              level is calculated as a logarithmic average of luminance in the
63              input image.
64
65       --verbose
66
67              Print additional information during program execution.
68
69       --help
70
71              Print list of command line options.
