Got opencv to detect eyes from the collection of portraits that I have. Got more than 1700+ eyes, that’s way more than the 100 or so I had. Eye detection with opencv works like a charm. There are false positives but the ratio is very small (10 out of 1500 or so)..
Using those and metapixel, I created a composite which you can see below:
Next step is to use something like zoomify to let you see the actual component eyes in detail.
