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.
