Spotting the digital clones: Your ultimate guide to surviving the deepfake epidemic

The age of digital deception has arrived, bringing with it a wave of sophisticated scams that leverage the power of artificial intelligence. Today, anyone with an internet connection can utilize advanced neural networks to create startlingly realistic video and audio forgeries, commonly known as deepfakes.

Can Artificial Intelligence 'Fix' Actors: Perfection for the Price of Trust?

[Translated] Artificial intelligence has moved from 'experiments' to routine: it accelerates work in pre-production and post-production, from rotoscoping and tracking objects to sound processing.

David Hernand Named Among Los Angeles Times’ 2025 “Entertainment Business Visionaries”

Simpson Thacher Partner David Hernand has been named among 2025’s “Entertainment Business Visionaries” by the Los Angeles Times. David was recognized for his work “representing marquee clients in transformative deals.” Highlights over the past year have included advising Metaphysic AI on its $1.43 billion merger with DNEG’s tech division to form Brahma AI; as well as leading Vice Media’s sale of Refinery29 and the relaunch of Vice’s digital brands through a joint venture with Savage Ventures.

The Challenges of Getting Neural Humans to Hug

In the first instance, the human figures are inferred from real-world footage using NVIDIA’s Instant Neural Graphics Primitives (Instant NGP) system, which rapidly creates a Neural Radiance Fields (NeRF) representation of the individual. Initially, a canonical NeRF is created (which means that the figure assumes a default, generic position, such as with Da Vinci’s Vitruvian man).

Bringing Camera Control to the New Generation of Video Diffusion Models

In order to maintain compatibility with MotionCtrl (one of the two rival systems tested, along with CameraCtrl), the authors trained their system on the same dataset used in that project – RealEstate10k. Only the novel aforementioned parameters of the first of the two spatiotemporal transformer modules were trained, with the rest of the network frozen.

Generative AI’s Captioning Crisis May Not Be Fixable With Large Language Models

Because generative systems such as Stable Diffusion and Sora use text/image pairings as the foundation of their understanding of images, the poorer or less accurate the text quality is in the source dataset, the less effective any model trained on such data is going to be.

Using Generative Adversarial Networks to Rethink the Selfie

In recent years, frameworks using Generative Adversarial Networks (GANs) have become eclipsed by subsequent synthesis approaches such as Neural Radiance Fields (NeRF), Latent Diffusion Models (LDMs), and, more recently, Gaussian Splatting. Therefore it was nice last week to come across a new paper, from Samsung Research, that leverages GANs, but makes use of some more recent techniques and adjunct technologies as well.

Detecting AI-Generated Images With Inverted Stable Diffusion Images – and Reverse Image Search

To test FakeInversion, the researchers selected a particularly recent group of baselines: DMDetect, a state-of-the-art method that operates only in the RGB space, and for which only an inference checkpoint is available; UFD, which detects

Powering Generative Video With Arbitrary Video Sources

The user’s text-prompt must therefore be semantically interpreted in two stages. The first of these is text vectorization, which uses pre-trained models from spaCY and Sentence Transformers to analyze the word vectors of the prompt and video label (captions, annotations or other metadata of the videos found in the dataset).

Improving Pose Estimation for Generative AI

There is much discussion in this period around the possibility of AI-generated TV and production output in the relatively near future – not just the amending of details (such as faces) that were captured conventionally in a studio or on location; but the actual generation of complete photoreal human stories, where AI-generated people walk in and out of situations, interact with the world and each other, act in accordance with logic and physics, and in general appear as if they were conventional screen actors.

Better Human Facial Synthesis With Gaussian Splatting and Parametric Heads

Metrics used were Peak Signal-to-Noise Ratio (PSNR), Structural Similarity Index (SSIM), and Learned Perceptual Image Patch Similarity (LPIPS). The tests focused on the facial region, with the authors using segmentation masks to isolate faces, not least since the underlying canonical head model has no provision for these satellite areas around the head.
