labels ? As in a legend? Or every area of a given type should have a text label drawn on the area if it is large enough and a label with an arrow pointing to the location if the area is not large enough to contain the label ?

hh(1) = line(nan, nan, 'color', 'b')
same for the other two colors into hh 2 and hh 3
legend(hh,{'water','tree','rock'})

@DANAH, that is way too vague. Add an image to what? Also, start your own discussion thread rather than here in @dakhli mohamed's 5 year old thread on an unrelated topic.
If you have any more questions, then attach your data and code to read it in with the paperclip icon in your new question/thread after you read this:

Ran in:
% add an image in matlab
sum('an image in matlab')
ans = 1658
