Unreal Engine’s latest demo videos show just how photorealistic the digital world has become

23 Mar

At this year’s Game Developers Conference (GDC), Epic Games showed off a new pair of demo videos that show just how capable its Unreal Engine has become thanks to advanced ray tracing technologies.

$ (document).ready(function() { SampleGalleryV2({“containerId”:”embeddedSampleGallery_4654967374″,”galleryId”:”4654967374″,”isEmbeddedWidget”:true,”selectedImageIndex”:0,”isMobile”:false}) });

The first video, seen above, is titled Rebirth and showcases just how photorealistic scenes can be when developed with the gaming engine’s technology. The demo, designed by the studio Quixel, highlights how realistic the lighting technology inside Unreal Engine 4 has become.

The demo was created by just three artists who developed it all using a standard version of Unreal and real-world scans from Quixel’s Megascans Icelandic collection. The result is a stunning showcase of textures and details that rival reality, as seen in the gallery of screenshots above, captured from the 4K stream.

The second demo is a teaser for an upcoming movie titled Troll. Still in the works, the movie is a collaboration between Deep Forest Films and Goodbye Kansas Studios. The short glimpse we get of it once again highlights just how realistic the animated lighting is in the scene, with the face of a woman being dynamically illuminated by little fire fairies of sorts.

As for what this means in the world of photography, the possibilities are seemingly endless. Aside from the inevitable point in time when we can no longer tell a rendering from an actual image — if it’s not already here — the ability to replicate precise lighting situations could open up the door to new software and technology that could not only help to simulate lighting setups in the digital world before testing them out in the real world, but also open up the door to adding realistic lighting to scenes and portraits in post-production.

Keep in mind that unless you’re viewing the videos in Google Chrome on a 4K monitor, you won’t be able to see them in their 4K glory. Even in 1080 though, the videos look incredible.

NVIDIA Research project uses AI to instantly turn drawings into photorealistic images

21 Mar

NVIDIA Research has demonstrated GauGAN, a deep learning model that converts simple doodles into photorealistic images. The tool crafts images nearly instantaneously, and can intelligently adjust elements within images, such as adding reflections to a body of water when trees or mountains are placed near it.

The new tool is made possible using generative adversarial networks called GANs. With GauGAN, users select image elements like ‘snow’ and ‘sky,’ then draw lines to segment an image into different elements. The AI automatically generates the appropriate image for that element, such as a cloudy sky, grass, and trees.

As NVIDIA reveals in its demonstration video, GauGAN maintains a realistic image by dynamically adjusting parts of the render to match new elements. For example, transforming a grassy field to a snow-covered landscape will result in an automatic sky change, ensuring the two elements are compatible and realistic.

GauGAN was trained using millions of images of real environments. In addition to generating photorealistic landscapes, the tool allows users to apply style filters, including ones that give the appearance of sunset or a particular painting style. According to NVIDIA, the technology could be used to generate images of other environments, including buildings and people.

Talking about GauGAN is NVIDIA VP of applied deep learning research Bryan Catanzaro, who explained:

This technology is not just stitching together pieces of other images, or cutting and pasting textures. It’s actually synthesizing new images, very similar to how an artist would draw something.

NVIDIA envisions a tool based on GauGAN could one day be used by architects and other professionals who need to quickly fill a scene or visualize an environment. Similar technology may one day be offered as a tool in image editing applications, enabling users to add or adjust elements in photos.

The company offers online demos of other AI-based tools on its AI Playground.

NVIDIA researchers create AI that generates photo-realistic portraits

19 Dec

NVIDIA researchers have published a new paper detailing their latest artificial intelligence work, which involves generating photo-realistic portraits of humans that are indistinguishable from images of real people. The technology revolves around an alternative generator architecture for generative adversarial networks (GANs) that utilizes style transfer for producing the final result.

Though GANs have improved substantially in only a few years, the researchers say in their paper that the generators ‘continue to operate as black boxes, and despite recent efforts, the understanding of various aspects of the image synthesis process, e.g., the origin of stochastic features, is still lacking.’ That’s where the newly developed alternative architecture comes in.

The team’s style-based architecture enables GANs to generate new images based on photos of real subjects, but with a twist: their generator learns to distinguish between separate elements in the images on its own. In the video above, NVIDIA’s researchers demonstrate this technology by generating portraits based on separate elements from images of real people.

“Our generator thinks of an image as a collection of ‘styles,’ where each style controls the effects at a particular scale,” the team explains.

Image elements are split into three style categories: “Coarse,” “Middle,” and “Fine.” In terms of portraits, these categories include elements like facial features, hair, colors, eyes, the subject’s face shape, and more. The system is also able to target inconsequential variations, including elements like texture and hair curls/direction.

The video above demonstrates changes involving inconsequential variation on non-portrait images, which includes generating different patterns on a blanket, altering the hair on a cat, and subtly changing the background behind a car. The style-transfer GANs offer superior results to traditional GAN generator architecture, the researchers conclude, with the photo-realistic results underscoring their assessment.

The latest work further refines a technology that has been growing rapidly over only a few years. Though GANs have been used in the past to generate portraits, the results were far from photo-realistic. It’s possible that technology like this could one day be offered as a consumer or enterprise product for generating on-demand life-like images.

Researchers create method for photorealistic Prisma-style effects

28 Mar

Popular app Prisma applies painting styles to photographs using neural networks, turning a snapshot into an artwork in the style of ‘The Scream,’ for example. But what if you could transfer photorealistic effects from one photo to another? Researchers at Cornell and Adobe have successfully demonstrated a method that will translate a variety of styles from a reference photo to another image, including things like lighting, time of day and weather.

Input image on the left, reference style image in the center, output image on the right. It’s not incredibly realistic-looking, but more realistic than your average Prisma treatment.

This could open up a whole new world of possibilities for ‘lazy’ photo editing. Say you snapped a photo of a rock formation in the middle of the day, but you’d rather it had the orange glow of golden hour. With this method, you could apply the textures and colors of a reference style image, i.e. some other rock formation at sunset, to your own image.

This photo-style-transfer method augments the neural-style approach Prisma takes by constraining the colorspace of the transformation applied to the source image. Taking a content-aware approach and classifying features like sky and water in each image helps to avoid mismatched textures and distortions.

Advanced photographers would likely be wary of making such drastic edits to their photos. However, the technology might appeal to someone who wants to apply the effects of professional lighting to a badly lit photo of an interior, for example.

What do you think? Could this technology be useful to you? Let us know in the comments.

Invisible Buses: Photorealistic Prints Provide Moving Urban Camouflage

03 Sep

[ By SA Rogers in Art & Street Art & Graffiti. ]

The streets of Vilnius, Lithuania are full of ghost buses that blend right into their surroundings while passing through intersections as if only existing in translucent ethereal form. Matching up to the scenery beyond when glimpsed at just the right moment, the buses are momentarily camouflaged thanks to photorealistic printed imagery mounted to their exteriors for this summer’s Vilnius Street Art Festival.

Lithuanian artist Liudas Parulskis collaborated with Studio Vieta to print full-scale scenes from the city onto public trolleybuses, a charmingly retro mode of transportation that has remained popular here despite being replaced by newer transit systems in many modern metropolises. ‘Vanishing Trolleybus’ is a temporary installation encouraging pedestrians to try to catch a glimpse or a photo of the effect in action at just the right ‘vanishing point.’

Paper People: Hand-Cut Zig-Zag Photorealistic Portraits

24 Jul

[ By Steph in Art & Sculpture & Craft. ]

paper cutout portraits 2

Tiny slivers are sliced away from a single, oversized sheet of white paper in a zig-zag pattern to reveal portraits of public figures, from Audrey Hepburn to Michael Jackson, in this series of photorealistic portraits by Korean artist Yoo Hyun. There’s no ink, graphite or paint involved – just an X-acto knife to cut out the negative space and tweezers to carefully peel those pieces away.

Take a close look at Hyun’s works and you realize how strikingly simple this process is, working a similar way to pixels. All you’ll see, when examining a small strip of one of these portraits, is a bunch of diagonal white lines. It’s amazing to see how much detail comes through, the portraits somehow revealing nuances in skin and hair texture, when you look at them from farther away.

The trick is in ever-so-slight variations of the thickness of each diagonal line of paper. Even the smallest cut-out can convey a shadow, while uncut areas make highlights pop. Pulling this off requires incredible precision, as a mistake the width of a human hair can affect the final outcome.

The Fabric of Guilt: Photorealistic Woven Textile Mug Shots

10 Nov

[ By Steph in Art & Photography & Video. ]

Woven Textile Mug Shots 1
The cringeworthy moment at which one’s accused guilt is captured forever (and often disseminated on the internet) results in a telling portrait of the subject. Mug shots reveal the emotions, personality traits and sometimes visual vestiges of the crime that was committed, and they’re endlessly fascinating for the world at large to look at. Artist Joanne Arnett exploits those qualities in a series of stunning self-portrait mug shots woven on a loom.

Arnett envisioned five characters, from a young celebutante type to a graying businessman, and transformed herself into them using makeup and props she already had on hand. She photographed herself in costume, digitally added the booking information, and then recreated each mug shot using wire and thread.

Woven Textile Mug Shots 4

The artist, who experimented with weaving facilities while studying at Kent State University, translated all the elements of each photograph into a highly realistic textile. The background patterns and colors were carefully researched to reflect the personality of the character displayed.

“Mug shots are taken at a point between conflict and resolution,” says Arnett. “The person being photographed is documented at a time where life has slipped out of control. There is no opportunity to prepare for the picture, and he knows it will be made public. So there is an interesting element of being alone yet also on display.”
