You can use them to stitch pictures in any arrangement (rows, columns, grids, random rotations, etc...) if that is what you mean. -- Bruno ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

What you want is a technique like the SIFT algorithm to identify similar features in two images. I recommend the autopano-sift tools: http://user.cs.tu-berlin.de/~nowozin/autopano-sift/ Also available is Autopano (which is a different program) http://autopano.kolor.com/ While you are looking at this, if you are interested in panoramas or even just trying to make a larger image out of two overlapping scans, you should also try Hugin http://hugin.sf.net/ These tools can be used together to streamline panorama generation and can be used to create fabulous (and massive) wide-angle images.

[Gimp-user] fuzzy logic possibly usefull to find almost perfect overlaps?
It regularly so happens I'd like to merge/overlap two digital pictures. Gimp does have tools to fit two pictures by hand (take one picture as a layer, and turn and twist them till they fit almost perfectly). However, almost perfectly may not be good enough, and I wonder if a search proce- dure could be develloped to find margins of two pictures that almost perfectly overlap? I suppose it will be impossible to find regions that really perfectly overlap, as the light may vary, a butterfly might happen to have come inside the picture, and so on. I may be mistaken, but as far as I know photoshop can automaticaly overlap two pictures. Did Gimp ever try to automaticaly achieve perfect overlaps of two pic- tures, and - if this had been considered impossible - have the merits of fuzzy logic been considerd to achieve this aim? -- Julien Michielsen ___ Gimp-user mailing list [EMAIL PROTECTED] https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
