NAME

       pfsoctavelum - Process luminance in pfs stream using Octave

SYNOPSIS

       pfsoctavelum <octave_program>

DESCRIPTION

       Use  this  command  to execute a GNU Octave program on luminance channel of each frame in the pfs stream.
       octave_program must be given in quotation marks ("") and must not produce any output (it  can  output  to
       stderr,  not  to  stdout).  Color  channels  are scaled proportionaly to the luminance channel. Luminance
       channel is represented by matrix Y.

       Note: This command requires GNU Octave.

EXAMPLES

       pfsinrgbe frames_%04d.hdr | pfsoctavelum "Y = conv2( Y, gaussian( 10, 1/5 )*gaussian( 10, 1/5 )', 'same'
       );" | pfsview

       Blur the sequence of frames with gaussian blur and show the result with pfsview.
