VIG_OPTIMIZE(1) 						       HUGIN							   VIG_OPTIMIZE(1)

NAME

       vig_optimize - Optimise photometric parameters

SYNOPSIS

       vig_optimize [options] -o output.pto input.pto

DESCRIPTION

       Photometric calculation can be performed on the command-line with the vig_optimize tool. This functionally is configured via 'v' variable
       lines in the .pto project file in a similar way to the autooptimiser tool:

       The camera response curve is simplified using the EMoR sensor model which reduces the variation to five numbers, these are the Ra, Rb, Rc,
       Rd & Re image (i) parameters (the default values of 0.0 are equivalent to an 'average' generic sensor).

       The vignetting model is represented by a polynomial with four parameters: Va (this is always 1.0 and doesn't need to be optimised) and Vb,
       Vc & Vd (which default to 0.0 - equivalent to no vignetting). The vignetting centre can also be different from the geometrical centre, this
       is specified by Vx & Vy (both default to 0.0).

       Exposure (EV) is represented by a single value Ev (defaults 0.0, equivalent to no-change).

       The white balance is represented by multipliers for the red and blue channels Er and Eb (the defaults of 1.0 are equivalent to no-change).

       A typical 'v' variable line configuration would look like this, i.e. optimise camera response curve and vignetting for image 0 and exposure
       for images 1, 2, 3 and 4:

	 v Ra0 Rb0 Rc0 Rd0 Re0 Vb0 Vc0 Vd0
	 v Ev1 Ev2 Ev3 Ev4

       (vignetting centre and white balance are left unchanged)

OPTIONS

       General options:

       -o file
	   Write results to output project

       -v  Verbose, print progress messages

       -p n
	   Number of points to extract

       -r  Extract random point (faster, but less accurate)

       -s level
	   Work on downscaled images, every step halves width and height

       -h  Display help summary.

       Expert and debugging options:

       -i file
	   Read corresponding points from file

       -w file
	   Dump corresponding points to file

NAME

       hugin_hdrmerge - Merge overlapping images

SYNOPSIS

       hugin_hdrmerge [options] -o output.exr input-files

DESCRIPTION

       TODO.

OPTIONS

       -o prefix
	   Output file

       -m mode
	   Merge mode, can be one of: avg, avg_slow, khan (default), if avg, no -i, -s, or -d options apply

       -i iter
	   Number of iterations to execute (default is 1)

       -c  Only consider pixels that are defined in all images (avg mode only)

       -s file
	   Debug files to save each iteration, can be one of:

	   a - all debug files (can only be used alone)
	   w - calculated weights from each iteration
	   r - result image from each iteration
	   s - source images before processing

	   If verbose >= 3, all debug files are output unless specified

       -a calcs
	   Apply one or more advanced calculations, can be one or more of:

	   b - biasing weights logarithmically
	   c - choose pixels with highest weight instead of averaging (overrides options -a b and -a d)
	   d - choose a pixel with the highest weight instead of averaging when all pixel weights are within 10% of each other
	   h - favour a high signal to noise ratio
	   i - ignore alpha channel
       -e  Export each initial weight to <input_file_paths>_iw.<ext>

       -l  Load a previously exported initial weight with respect to the input file names

	   NOTE: if both -e and -l options are on, the program will calculate and save the initial weights, then wait until user indicates that it
	   can continue by loading the previously saved weights

       -v  Verbose, print progress messages, repeat for even more verbose output

       -h  Display help summary.
