Description

Hello everybody,

it would be good (at least for the Semi-Automatic Classification Plugin) to allow for the selection of the statistics source (STATS_SRC) for the supervised classification and the selection of the table containing class statistics (STATS).
Maybe something like this:

ParameterSelection|STATS_SRC|Get class statistics from|[0] Training Areas;[1] Class Table

This way the classification process would be rapider because class statistics can be calculated only once, saved in a .txt file, and used for the following classifications.
Also, it allows for the classification of image subsets that are outside the extension of training areas.

Thank you.

Cheers!
