Thanks for the explanation.
What I think is important to note here is that there are two types of users who will use this
feature:
1. Users who simply want to know if there is a match (i.e. a bool return value is sufficient)
2. Users who want to know the details of the differences
The object return type that Kamil mentioned was something I was considering as well, but I was
concerned that it would be a bit verbose for type 1 users and would necessarily incur the overhead
of object creation. (This is probably an unnecessary concern, as image analysis takes much longer.)
