I’ve finished doing perspective corrections on 250 photos of NHCP #HistoricalMarkers! 🎉 I have been doing this sort of photo editing on and off since 2017 and this is in support of the historical markers @wikidata /Commons project I and a few others are working on (e.g., my Panandâ mobile app).
Generating the mosaic image in my previous toot was an interesting micro-coding project. I conjectured but didn't expect that it was possible to arrange photos of varying sizes into a near square. I just used a naïve randomized heuristic to essentially solve a variation of the bin packing problem¹ and the results turned out to be good enough™ though obviously not rigorously optimal. Thanks also to the MediaWiki Action API!
