I just noticed that a question I provided an answer to (How to find face shape and points to fix eye glass ) has been closed as a duplicate of this question: iphone app to recognise eyes in a scanned image of a person).
I don't think my answer is particularly great, though it addresses the question with some specific references to code and to an extensive tutorial. Also, it is addressed to what I estimated as the novice experience level of the OP. On the other hand, the question cited as a possible duplicate has two answers which are very general to the point of a discussion.
Do the moderators closing questions as duplicates make any judgement as to the comparative quality of the questions or which has the better answer (if the possible duplicate has any answers) or is it simply a matter of which was asked first?
In this case I don't think the question is actually a duplicate but appreciate that it doesn't much matter in the scheme of things.
