+Segmentation works on raw RGB images, but respects and retains
+`AlternativeImage`s from binarization steps, so it's a good idea to do
+binarization first, then perform the textline detection. The used binarization
+processor must produce an `AlternativeImage` for the binarized image, not
+replace the original raw RGB image.
