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.
