Hi,

 If I am dabbling in photogrammetry and using Photomodeler or similar to create a 3D model of an existing building but I want to reskin the building using some spiffed up textures. (Like stone VS brick or something.) Is there a way to not just select areas of photos by color, but to select by representative texture sample ? In other words, is there a tool out there that will match areas by pattern recognition ? Otherwise would using Live Trace in Illustrator help in this regard ?
 
 It's not that selcting wall surfaces on a single building would be terribly time consuming, but we're talking about lots and lots of buildings : ) Any insights on a way to automate the process would be most welcome.

 Thanks,

 there's not a way that i'm  aware of, but then, i've not come across this need, so it's not to say it can't be done, and we've already talked about learning new stuff everyday.

i'll play around and see what i can come up with.

 of course its possible..it asks a lot of patience and time but it can be done..
This is what i do..
You make paths of every textures you like and make alpha masks of them..I guess if you work with illustrator you manage the pentool..
Once you have a path you can for exaple make a brush of your texture or you can convert it to a shape..This is not a method that can be done in a few minutes but its the best way to select the things you want..I hope this makes sense
