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 AUTHORS

tca_correct - Calculate transverse chromatic aberration SYNOPSIS
tca_correct [options] inputfile <inputfile> is the base name of 4 image files: <inputfile> Colour file to compute TCA parameters red_<inputfile> Red channel of <inputfile> green_<inputfile> Green channel of <inputfile> blue_<inputfile> Blue channel of <inputfile> The channel images must be colour images with 3 identical channels. If any of -R, -G, or -B is given, this file name is used instead of the derived name. Output: commandline arguments for fulla DESCRIPTION
Generates fulla command-line parameters for correction of transverse chromatic aberration (TCA) from sample photos. Ideal sample photos would have a lot of contrast over the entire image area, little saturated colour and no blown highlights. OPTIONS
-h Display help -l input file is PTO file instead of image -m method optimization method (0 normal, 1 newfit) -o optvars string of variables to optimize ("abcvde") -r Reset values (this will zero a,b,c,d,e params and set v to 10) makes sense only with -l option -s <scale> Scale for corner detection -n <number> number of points per grid cell (default: 10) -g <number> divide image in <number>x<number> grid cells (default: 10) -t num Remove all control points with an error higher than num pixels (default: 1.5) -v Verbose -w filename write PTO file -R <r> Use this file as red channel -G <g> Use this file as green channel -B <b> Use this file as blue channel AUTHORS
