Listen friend, I'm using it as a concrete example of a technology in every case.
Today I'm using it as a concrete example of H.265 (BPG) as an astonishingly good alternative to JPEG in applications where you control the encoder and decoder.
This account exists ONLY to talk about that app. Every one of my projects is isolated from the others by using different accounts, etc. We should all be meticulous about compartmentalizing our online identity.
This app uses an unusual image codec (BPG) which illustrates that if you control the encoder and decoder, you can choose a format with no mainstream support. I think it is a good point.
Be careful working in this field (pornography). In 2017 I wrote a mildly pornographic app (http://driftwheeler.com) and it appears on my resume. When hiring managers or recruiters take a look, some of them get upset.
For example, a scheduled interview was abruptly cancelled the night before. I pursued the matter through a friend who had a senior role at the hiring company and it was determined that the (middle-aged female) in-house recruiter had been deeply offended when she followed the link on my resume and had cancelled everything. Eventually, I received a sincere apology from the CEO.
There is a real stigma, and it will affect you. Beware.
In 2017, on a low-end GPU, the indexing took about 10 minutes of 100% utilization, for a dozen patches covering each of 50,000 images (feature vectors were 1,024 32-bit floats).
After that, the app just queries a precomputed list (256 precomputed matches per query) depending on where in the image the user pressed. Even with hundreds of simultaneous users, it can hardly keep a $5 Linode busy.
Similarly, I've been writing respectable software for decades but I'm fairly certain that my most widely used piece of software, by a wide margin, is a mildly pornographic app (http://driftwheeler.com)
This app, published in 2017, has a continuously growing population of users from all over the world. I get email every day asking whether soft1 is the only server, thanking me, suggesting improvements, etc.
It's ironic, and there is a lesson to be learned here.

Not safe for work. Pornography advertising.
I get a cut of the monthly fees when somebody signs up for MetArt.
