Comment on Determining image similarity by Brett Spurrier

Interesting post. I have been following image similarity algorithms for a while but I haven’t found any that scale very well. Cross correlation gives great results, but try doing that across a million plus images.

I wrote a small SDK that I use in my iPhone AppStore app (called eyeBuy) which scans 5 million plus images in a few seconds. If you are interested, I can port it to whatever platform you are using. Have a look: http://sites.google.com/site/imagecomparison/

Yes, the images have to be the same size. Btw, this post was more of a thought experiment, I’m sure there’s more robust ways to do image similarity out there.

I tried this, adding zeros as Amit proposed. However, with the images I tested, it did not work.

Are there any restrictions to this? Do the images need to be the same size?

Hey Victor,

Thanks for the suggestion of Scrapy, I’ll definitely check it out. I created a branch for an Erlang-based crawler, but I definitely missed Python’s html parsing niceness. The fact that it uses Twisted (and not threads) is a big plus.

Hi!
You’ve got a cool idea with couchdb crawler.
Have you seen scrapy crawler (scrapy.org)?
It’s built on top of Twisted and it’s smart.

just resize the images to 128×128px and will be much faster
