I have been working on moving automatic classification signature files<br>
(ones used by i.maxlik and i.smap) out of imagery groups. Existing<br>
approach was not flexible enough as there was no official way of how<br>
to reuse signatures from one imagery group in another group (train on<br>
one, classify many).<br>
At the moment I have managed to implement all internal bits of fully<br>
reusable signatures – at the time of creation, band references are<br>
written to the signature file; before signature use, band references<br>
are used to reorder signatures to match band order in the new group<br>
(or bail out if bands do not match).<br>

There are only two bits left before this work is complete:<br>
1) remove current special signature file handling in GUI;<br>
2) signature management.<br></blockquote><div><br></div><div><div class="gmail_quote"></div><div class="gmail_quote">There are 3 add-ons that Luca wrote at OSGeo code sprint in Bonn 2018: i.signature.copy, i.signature.list, i.signature.remove. <br></div><div class="gmail_quote"><div>Would they be of help for any of the options proposed?</div><div><br></div><div>In any case, thanks for your impressive work!</div><div><br></div><div>Cheers,</div><div>Vero<br></div></div></div><div> </div></div><br></div>
