Enhancing Photorealism Enhancement
Stephan R. Richter, Hassan Abu AlHaija, and Vladlen Koltun

Paper: https://arxiv.org/abs/2105.04619
Code and data: https://github.com/intel-isl/PhotorealismEnhancement
Project page: https://intel-isl.github.io/PhotorealismEnhancement/

We present an approach to enhancing the realism of synthetic images. The images are enhanced by a convolutional network that leverages intermediate representations produced by conventional rendering pipelines. The network is trained via a novel adversarial objective, which provides strong supervision at multiple perceptual levels. We analyze scene layout distributions in commonly used datasets and find that they differ in important ways. We hypothesize that this is one of the causes of strong artifacts that can be observed in the results of many prior methods. To address this we propose a new strategy for sampling image patches during training. We also introduce multiple architectural improvements in the deep network modules used for photorealism enhancement. We confirm the benefits of our contributions in controlled experiments and report substantial gains in stability and realism in comparison to recent image-to-image translation methods and a variety of other baselines.

"Reshade mod + GTA IV filter"

~ Khaby Lame for GTA V~

A bit too dull for my liking. Though it does make the city areas more attractive ngl.

L CH says:

The fact that they trained on low res game engine cringe me 😂😂😂 I want to see Ultra 4k and 60 fps with this now !

SDRIFTER Abdlmounaim says:

this sounds like an awesome AD, that i didn't actually skip !

vallewasgeddney says:

Video in 720p…

FreddyKruegerFiles says:

Don’t let this distract you from the fact that Hector is going to be running three Honda civics with spoon engines, and on top of that, he just went into Harry’s and bought three t66 turbos with nos, and a motec exhaust system!

"Hey, let's spend a fuckton of money on highly advanced image enhancing technology and then make a Youtube video in 720p to present it."
His coworkers : "Brilliant idea!"

JiggliJellifish says:

This guy sounds like the dude from the Aperture Science Enrichment Center, or the FNaF person.

Teddy Merzliakov says:

It shows the difference between "realistic" (just super detailed and flashy) and realistic (it looks like real life)

Ricardo Amendoeira says:

From the description of how this works I can't understand how it's so temporally stable, if it works frame by frame with no memory.

lowercase v says:

The slight exaggeration and smoothness of physics on the GTA engine kinda gives it away its not a real video.
But when you stop the video, that single frame is most of the time so indistinguishible from a real low-quality dashcam frame… its just scary 😮

HarryC26 says:

they just made it into gta 4 lol

Penney Sound says:

You've made it look more realistic by making it look worse

Sinisa Vlahovic says:

Can't wait to implement that on human faces

Oscar M says:

this has to be a hoax lol

Bartacomus Kidd says:

Can you do something with Eagle Dynamics Digital Combat Simulator? Their scapes are the worst.. the simulation, is the best.

Dushmany says:

Watching this video, I had a massive ‘Technical Jargon Overload’ flashback.

Johnny Sun says:

or you could just go outside

AM44R_ says:

imagine having that as a real mod in gta

Jason Davies says:

Oh yeah I know exactly what you're talking about

Buddhabrot xiii says:

rockstar couldnt even bother to fix their biggest game's loading time.
it was just a normal person that looked at it, and simply fixed it.
rockstar doesnt care about their fans, the people giving them money.

Pet2k says:

Am I the only one who thinks that the realistic side looks like GTA IV shading and colorgrading?

Dev UP says:

imagine playing like this in vr.. i would love it

Your Final Meal says:

cool af; but i wouldn’t like to see it implemented in future games as default. gta has always been about exaggeration of reality, soooo the visual aesthetic fits perfect imo. maybe a filter option tho 🙂

Toxic Rain says:

Maybe should have taken the reference from California? cause making GTA look like germany taken with a non color correct camera is kinda meh.

Elixir says:

Ye olde does not upload in HD so it appears more realistic trick.
