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.
