NAME

       pfstmo_pattanaik00 - Time-dependent Visual Adaptation Model

SYNOPSIS

       pfstmo_pattanaik00 [--time-dependence] [--fps <val>] [--mul <multiplier>] [--local] [--cone <val>] [--rod
       <val>] [--verbose] [--help]

DESCRIPTION

       This command implements a tone mapping operator as described in:

       Time-Dependent  Visual  Adaptation  for Realistic Image Display.  S.N. Pattanaik, J. Tumblin, H. Yee, and
       D.P. Greenberg.  In Proceedings of ACM SIGGRAPH 2000.

       This operator requires properly calibrated image  data  (in  cd/m2)  and  its  results  should  be  gamma
       corrected.

       The local version of this operator is based on the following paper:

       Adaptive  Gain  Control For High Dynamic Range Image Display.  S.N. Pattanaik, H. Yee.  In proceedings of
       SCCG 2002.

OPTIONS

       --time-dependence, -t

              Use time dependent model of adaptation. This should be used for tone mapping of an  animation.  It
              has  no  influence  on  single-frame  input.  Switched  off  by default.  Note: it is important to
              correctly set the speed of the input animation (--fps).

       --fps <val>, -f <val>

              Speed of input animation in frames per second. Used when  time-dependence  is  switched  on  (-t).
              Default value: 16.0

       --mul <multiplier>, -m <multiplier>

              Multiply  input  values  by  a  multiplier value.  Useful if input data is not calibrated. Default
              value: 1.0

       --local, -l

              Use local version of the tone mapping. Time-dependent effects  are  cancelled  while  using  local
              version, global version is used by default.

       --cone <val>, -c <val>

              Set  the  adaptation  level  for  cones.  If  --rod  parameter is not used, this will also set the
              adaptation level for rods. By default, the adaptation level is calculated as a logarithmic average
              of luminance in the input image.

       --rod <val>, -r <val>

              Set the adaptation level for rods. By default, the adaptation level is calculated as a logarithmic
              average of luminance in the input image.

       --verbose

              Print additional information during program execution.

       --help

              Print list of command line options.
