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.
