TLDR; If I had to guess performance will be a bit higher on raw imagery for detection and maybe a lot better for classification, but it introduces complexities if you want to count or estimate the size of trees.
This is something that we're actively experimenting with for a project on birds using DeepForest. I'm fairly sure we've run DeepForest for people on tree data that isn't in an orthomosaic and it works fine, but we haven't done any analysis on differences for the trees.
Intuitively here's my guesses, but I'd also be curious what @bw4sz thinks:
We're working on solutions that integrate the two approaches but that's early phase work (based on https://easyidp.readthedocs.io/en/latest/index.html) and so I wouldn't recommend waiting for it to get started.
Hey :)
I am about to use DeepForest for a University Project. Therefore I have a question regarding the input data and the resulting perfomance: Do you have any knowledge if the model performs better if the input data is a tile from an orthomosaic? I have several RGB Images from a UAV. Now I have the option to take the raw images and label them and take them as an Input for the model or I first create an orthomosaic and then get tiles from that and the label them and take them as an Input. Surely I could try both approaches, but that would mean I have to label twice, what is time consuming -> so the question is, if you have any experience on that and on the perfomance? (Of course the perfomance depends on several factory)
Thanks
