Hello, I would like to know if it exists a package including something equivalent to this page: http://www.developpez.net/forums/d740403/autres-langages/algorithmes/contribuez/image-geometrie-projective-homography/ http://www.developpez.net/forums/d740403/autres-langages/algorithmes/contribuez/image-geometrie-projective-homography/ I've searched with these keywords: R-project homography warping, but with no success. I'm not very good at R and I don't know java. So any help is welcome. Have a nice week-end, Ptit Bleu. -- View this message in context: http://r.789695.n4.nabble.com/Homography-with-R-tp3837111p3837111.html Sent from the R help mailing list archive at Nabble.com.

It illustrates the use of the 'trans3d' function which I think does the transformations described in the paper that the first poster linked to. Mind you, I don't read French so I cannot be sure this will satisfy.> I'm not very good at R and I don't know java. > So any help is welcome. > > Have a nice week-end, > Ptit Bleu. > > > > -- > View this message in context: http://r.789695.n4.nabble.com/Homography-with-R-tp3837111p3837111.html > Sent from the R help mailing list archive at Nabble.com. > > ______________________________________________ > R-help at r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code.David Winsemius, MD West Hartford, CT
