Thanks for pointing to the link, which perhaps should be mentioned in
the "individual documentation", which is what
users check to find help.
The actual recipe is using a generic "input_image" as input. I think it
would be better an actual example as done in the "individual documentation".
Also, despite making reference to the article by Michel, Youssefi and Grizonnet,
the actual values of the parameters do not follow the recommended
relationship of 50% value
for range and spatial radii between step 1 and step 2.
Finally,
the sentence "The segmentation will group together adjacent pixels
whose range distance is below the ranger parameter and (optionally)
spatial distance is below the spatialr parameter"
is confusing because adjacent pixels are, by definition, at an spatial
distance of 1. I think you should use "neighboring" instead of
adjacent, or clarify that you use "adjacent" in a generalized
way in which adjacency is assumed for pixels at an spatial distance < spatialr.
