Yes. Visitor is a convenient pattern to perform a computation over each element of a recursive data structure. This pattern works well for trees. You need to pay attention to cycle when using it on a graph. This might be expensive if you have a large graph and you use a set to keep track of the element you run over.
Do you want to do this on any object of the image?
