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 quo-
       tation 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.

BUGS
       Please report bugs and comments to Rafal Mantiuk <mantiuk@mpi-sb.mpg.de>.
