pfsoctavelum − Process luminance in pfs stream using Octave
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.
frames_%04d.hdr | pfsoctavelum "Y = conv2( Y, gaussian(
1/5 )*gaussian( 10, 1/5 )’, ’same’ );" | pfsview
Blur the sequence of frames with gaussian blur and show the result with pfsview.
