OkCupid a blog post on detecting similar images that have scale and cropping applied.https://t.co/F0dvINf3WZ

Here is a method to detect basic photo filter manipulation signature, https://t.co/QNEdDmh1OR

Nvidia has a thing that can remove watermarks / text and even de-noise an image quickly. Not sure if it's released, but something like that would be good at removing the stuff OkCupid talked about being thorny problems.https://t.co/nNhQ051UGp

Disney also shows you can use similar ideas against videos (at least the denoising one).https://t.co/9C9IkEx9Jg

I can't find much on the system YouTube uses, but they seem to have rolled out a similar distortion detection mechanism as part of their Content ID apparatus. I can't find anything directly about it, reports say its now being done with 'Google Brain'?https://t.co/vRQqYMa5wL

Noise detection is neathttps://t.co/3jVC9v3FsI

Two Minute Papers covers that Nvidia thing in more detail: https://t.co/PK3L1xoseq

Oooh, it has a link to a knock-off implementation using Kerashttps://t.co/DPWMX4m62m

Anyone know of good sources for information on modern perceptual hashing techniques? This paper talks about using them to track meme lineages.https://t.co/8GZkDBShcvApplying the techniques to a corpus might net interesting patterns like this one: https://t.co/xY3gPE1A2Q

Ah, its seems someone already did what I suspected was possible.https://t.co/bBnDqm7fqU

What's wild to me is that their approach was published only a month after nvidia's denoising one, basically suggested they either used the same technique, or discovered the same roughly similar solution due to similar constraints.

Belhassen Bayarhttps://t.co/GzAnwOPZx7 andMatthew C. Stammhttps://t.co/mhdrj1CDSLHave some great stuff on detecting image manipulation. Some of the latest work accounts for nuances in camera make/model.https://t.co/Km12uBBsiIMight be good to detect deep fakes.

I am excited about algorithms to thwart spoofing of images and fakes.https://t.co/3gczPDFKMZ
