Intel applied machine learning to GTA V, and it looks too real

[McMurdeR]

Why are the ML pix so green, flat, and dull? I must be missing something because well, this seems obvious.

I think my area looks more like the GTA V pix. But - no graphics expertise.

Yea, they look like they were taken with a bad camera on a very dull day. Colour is miles off. Still impressive though.

Does look like the training images have soured the results. Should have had used Cali footage instead.

Is it just me or did they just use a lot of computational power to make it look worse? The renders do not look more realistic to me at all. I prefer the images generated by the game.

Well no, green is a primary color. So, Green is green, and all of those pictures are too green..

When "green goes to blue", that color is called, "cyan". An when "red goes toward violet", that color is called, "magenta".

It helps if you try and remember a gentleman named, "Roy.G.Biv",.

To recap. there are three primary colors, and three "secondary" colors, in this order: Red, yellow, Green, cyan, Blue, and magenta, then back to red.

This explains "subtractive" color printing theory:

And here's "additive" color theory:

I can assure you that, (IMHO), all of those " AI interpreted images", are too green. My monitors are set at about 5600 K (daylight color film balance, slightly warm), and I was able to neutralize the color by dialing back the drive on the green color channel. (via a "levels layer", in Photoshop..(see photo in post #22)

FWIW, there is no such thing as "windshield color balance", since your eyes (in concert with the brain) adjust to any reasonable color offset the windscreen may introduce. Thus,while any color recording device, (film or digital) may "see" color differently than a human, those results have to be adjusted back to what a person expects to see.to be realistic. A classic example of this is the "skylight 1A" filter, which removes blue from pictures taken in shade, which a human would interpret as, "too blue"

it helps English being your first language, which to me it's not. But I will just say this - I do monitor calibrations, I have hardware calibration device etc. Images have blue hue added to them. Period. That's calibrated for color critical work, 6500K 120cd/m2.

Everybody else here thinks it's blatantly too green. So, I guess you're the only person here who knows what they're talking about, period..

Yet somehow, and very oddly I might add, I transferred the photo to another machine, (with obviously a different monitor), and it still appeared the same way too green on that.

I don't have a color spider, but I do have an AAS degree in photography.

Looks great to me (with further refinement to be done), just wish they had uploaded to Youtube in a higher resolution.

The research team were probably unable to get hold of a RTX 3090 required to run ML at a high enough resolution.

And I have one bachelors in graphic design... I can remove the blue tint and get the correct colors. You can too. If you go and remove green, well..good luck with that. 120cd/m2, 6500K. Photography lesson for free, to you, from me.

"A color temperature of 5000 K (D50) is standard in the field of desktop publishing (DTP) for printing or publishing. This is the color temperature recommended for lighting by the Japanese Society of Printing Science and Technology when evaluating colors for print applications. While this standard might give a distinct reddish cast to whites in pictures prepared to the standards of television video or similar images, it is intended to reproduce the look printed colors have when viewed under conditions close to direct sunlight".

Courtesy these guys :https://www.eizo.com/library/basics/color_temperature_on_an_LCD_monitor/#:~:text=A color temperature of 6500,among their color temperature options.

The reason you're getting "too blue", is because your monitor is set too blue, by photographic and publishing standards, or you're color blind.

The only earthly reason to set one definitive standard for all the camera and monitors to one white point in a given industry, is so everybody "sees", the same thing inbitially. Any given producer is likely to interpret the final output colors seen,, to his (or her) personal taste, or for creating the mood desired. anyway.

Still, all of us here, (besides you), interpret the AI scenes as "too green".

Not to mention the fact that so many people are complaining of eye strain, from monitors with "too much blue" in them.

Ramp the color temperature down to 5600 K (noon in June daylight), and the problem goes away.

 

[Ludak021]

Well the standard in every firm I worked for was the one I wrote here at least two times already. And this is both for print and web, but print is so much more complicated we should leave it alone.
PS. I have never met a designer following 5000K or using anything but 6500K and 120 candles. Don't just paste random stuff like that. I am sure LG will recommend using OLED and nothing else...I mean..

now that's completely unfounded and you kinda lashing out a bit. Chill man.

 

[alexnode]

They trained the machine learning algorithm with dash cam footage or cctv. Bad colours, bad camera, no definition , sunlight inexistant. Even a 5 year old phone will have better colour grading and definition.

Lashing out? Hardly. The photos done with the AI are too green. Everybody here, save for >you<, say they are "too green" I fixed one in Photoshop with a levels layer by ramping down ONLY the green center point. I then uploaded it. See post #23

Disregarding whatever color temp my monitor is set to, it's a whole lot nearer to correct than it was

Now, you're the person who started the "monitor color temperature issue", NOT me. Thus, you reap what you sow

Your monitor needs color calibration. :/
The whole thing has blue tint, green is blueish, red is pulling into violet and so on, like you've put monitor to 9600K instead of 6500K

Incidentally, the color temp setting of a monitor, is at least partially dependent on the color temp and level of the ambient light in which it is used.

Which means, the quality of the ambient light, will also affect your perception of the colors on your monitor
