Which is completely wrong by the way, JPEG-XL quantizes its coefficients after the DCT transform like every other lossy codec. Most codecs have at least some amount of range expansion in their DCT as well, so the values quantized might be greater bit depth than the input data.
I do not understand the connection between the patent concerns in the article and open-source 3D printing. In particular, the patent issues seem to be the case for all non-Chinese 3D printer companies, whether open source or not. I am not sure how sharing your designs makes this worse (I suppose with the original drawings it's a bit easier to write a patent in bad faith - but certainly not necessary). Something like a defensive patent grant might make a lot of sense (see Opus, AV1 etc) but that's also independent of whether the implementation is open source or not.
The AR coefficients described in the paper are what allow basic modeling of the scale of the noise.
> In this case, L = 0 corresponds to the case of modeling Gaussian noise whereas higher values of L may correspond to film grain with larger size of grains.
Almost none of the games pictured are actually "doujin" games - they are commercial publishers.
Also, the reason we don't remember PC-98 is because it was never sold in the US (except for the very unpopular APC-III). It was the most popular computer on Japan from late 80s to early 90s and is well remembered there. Being the most popular PC, there is a huge amount of software for it, including huge amounts of office and productivity software, many genres of games, and plenty of Western ports.
I agree. I posted a documentary on actual doujin gamedev in Japan, but it looks like the documentary was removed from Youtube. You can still find it on archive.org though for those that are interested in the scene.
And there similarly was a market for relatively low-budget and/or pornographic and/or copyright-infringing computer games in western markets, it's just that people today find weird old ecchi VNs with anime art more interesting than weird old strip poker games with digitized photos.
I agree. Whilst it's great to see a mention of PC-98 the article views it through a very odd lens, and gets a lot of things confused or even just plain wrong.
You don't need to store two whole independent images. The high quality image can predict from the low quality image, and the low quality image can be a lower resolution, too. It is less efficient than storing one image, but more efficient than storing two independent images.
Digital video tape formats (e.g. DV, HDV) are an example. Other containers that operate in this mode are TS and Ogg (and optionally, MKV). Any sort of live streaming format generally is, too.
Depends on the car. My Bolt battery takes a LONG time to get warm just from driving, even with the battery heater running. You can speed it up a bit with yoyo driving (speed up to use power, then regen brake to dump power back into the battery, repeat as necessary) for about a half hour.
