6 ptoclean - prune improbable control points
7
9 ptoclean [options] --output better.pto notgood.pto
10 Options:
12 -o | --output Filename of pruned project (can be the the same as the input)
13 -n | --amount Distance factor for pruning (default=2)
14 -f | --fast Don't run the optimiser for each image pair (similar to APClean)
15 -v | --verbose Report some statistics
16 -h | --help Outputs help documentation

19 ptoclean takes a hugin .pto project and removes inconsistent control-
20 points. 'Bad' points are determined by calculating the average error
21 distance and standard deviation (Sigma), then removing any points with
22 an error distance greater than the average by n * sigma. This pruning
23 is performed on each pair of images in turn and then finally on the
24 project as a whole.
25 Additionally the autooptimiser tool is run on each pair of images
27 separately before each calculation, so there is no need for the project
28 to be 'nearly aligned' beforehand.
29 NOTE: although optimisation plays a part in the pruning process, the
31 output project is exactly the same as the input except with 'bad'
32 points removed, you probably want to optimise the geometry of this
33 project with hugin or autooptimiser afterward.
34 This tool is heavily inspired by APClean, a similar tool for PTGui
36 project files by Fulvio Senore. If you want a similar behaviour to
37 APClean without the optimisation steps, use the --fast option.
