Re: Hash list
I wonder whether the people who do this research (and I am seriously glad I am not one of them) has looked at using the 'bag of vectors' approach - I saw some work a few years ago, very impressive at identifying the same types of features - matching objects taken at different angles. Computationally expensive, of course, but that's always something that can be dealt with. I have to say that I'm not surprised to hear of the hashes (from a technical perspective), but it's in contrast with what I heard on the radio the other day about how long it takes the police in the UK to search through devices. I would be interested in looking at the accuracy of taking a cluster of approaches (whole image hashes, partial hashes, feature hashes, even key word analysis).
