But I actually want to know what I'm missing-- what's interesting about this "closed source but available for academic purposes" application which appears to simply be a re-implementation of existing work?
I'm trying to give benefit of the doubt here actually.
- ahknight 12y agoIt's using a very similar technique to pHash, actually. DCT-based hash and all. It's not brand new, but perhaps a variation on a theme. I've actually been working in this domain for the last week or so and DCT-based hashes are quite accurate, but slow as hell. Average hashes (aHash) or Delta Hashes (dHash) are much faster and rather good at weeding out large numbers of images. A mix of ideas is usually a good idea.
- opless 12y agoYup, it's been shown that the accuracy of a set of poor classifiers together can be greater than a known 'good' classifier. The implication is that there's no single 'perfect' classifier for a problem, engineers have used this notion for many years having multiple systems vote for fail-proof operations.
