I have a general question regarding if there are any existing guidelines on the parameters choice of the spatialr and ranger values. How do I understand the range I need to apply in order to test different values to pick the best results regarding my application etc?
More specifically, consider I use UAV very high resolution ortho images with pixel size of ~8cm with data from a multispectral sensor, and I use e.g. 2 or 3 bands, like RGB.
How do i pick a value range for the params?
I have tried a lot of things, and at some range the outputs do not change at all, not even the number of segments.
More specifically, the only thing that seems to matter in all of my combinational tries with extreme ranges of values is the “ranger” radiometric distance parameter, and neither “spatialr” nor “minsize” make any difference at all in the resulting segmented output.
Thanks in advance for helping me to get a deeper grasp of the segmentation algorithm
