I am doing my thesis research about analyzing settlements in Mali with Sentinel2 images with the use of the program eCognition (object-based). We have trouble with determining the settlements because they have almost the same spectral values as the surrounding (the houses are from loam, the same as the ground, see picture..).
A few things I already tried / analyzed for inserting conditions for classification:
- Means from all the Sentinel-2 layers
- Standard deviations from all the Sentinel-2 layers
In the picture beneath, the area and two examples of settlements are visible.
I hope you could give some suggestions.
