Using SAMGeo with RGB Sentinel-2 for Pixel-wise Regression and Fine-tuning?

[josephxlp]

Hi,
I’m working with RGB Sentinel-2 imagery, and I’d like to know if SAMGeo can be used or adapted for my use case.

Specifically:

Can SAMGeo operate effectively using only the RGB bands from Sentinel-2?

Is it possible to adapt SAMGeo for pixel-wise regression (rather than segmentation/classification)?

Can SAMGeo be fine-tuned on Sentinel-2 RGB data for a regression task?

Any clarification, limitations, or pointers to example workflows would be very helpful.
Thanks!

SamGeo supports 3 channels and segmentation tasks only.

For more than 3 channels, check out the GeoAI package: https://github.com/opengeos/geoai. However, it does not support regression tasks yet.

Thanks very much for your reply. I will try work implementing the regression and if it works, I will let you know
