Forgot to say: In the other hand, I opened a topic asking for a "color classification". I doesn't work, because some parts of the cliff and some bushes that have the same RGB color (same values to the Green channel). So, deleting this value from the Green channel will also delete some part...

Thanks for your guessing Daniel, you were right after all! :) And Dimitri - even if you called me BrunO...it's BrunA, but its okay, no problem :) - thanks so much for your explanation, I was thinking that it could be a problem with the model and its density, and I'm now totally agree with you that i...

Yes, of course.
Here it is....

Hi again, So my question is... it is REALLY possible to classify a point cloud made not by a LiDAR laser scan but through photogrammetry ? I tried but some subsamples may loose this "dimensionality", causing some errors around trees, bushes and vegetation - even if green areas are correcte...

Okay, gonna try.

Thanks

Hi, It is possible to classify some colored areas? I put some red spots in my scene and they are tinny but I would be glad to separate them from my cliff. It's complicated to do it with CANUPO because they are flat as my cliff, so they won't separate at all. I found something in Edit > Colors > Conv...

Ok, right.
I'll try again later cause I guess it was a density problem, indeed. It also does make sense to me, thanks for your explanation about the descriptors.

Hi, I'm having a problem in CC canupo classifier. When I make the cloud point classification with two samples (grass and rocks) in a scene, the CC sends me a message like that: "some descriptors couldn't be computed (min scale may be too small). I don't really understand what it means and it se...

That works, I've never seen this file so it's much better than the other I have (Maybe not the complete). Thanks a lot :)
I'm gonna take notes from every question I have and I'll send you later for you to create a FAQ.

Thanks for this implementation, that's nice! I've had a lot of dificulties with this tool while using it in the prompt. I'm a very new user of all these tools (like cloudcompare, meshlab, etc.) and I'm not used to manipulate certain values. Can anyone explain to me that thing of scales? I'm sorry bu...
