Pixel-Space 👏

New paper: AsymFlow🔥

JiT x0-prediction is not enough for pixel generation. Better keep velocity in a low-rank subspace:

- 1.57 FID on ImageNet (best pixel flow model)
- Finetunes FLUX.2 klein into pixel space, beats the original on HPSv3/DPG/GenEval (#1 overall on HPSv3)

Preparing a major PR to improve @ThreeJS MaterialX support significantly. In order to perfect it, I've written an open source @MaterialXcg Fidelity Suite inspired by the @thekhronosgroup / @glTF3D fidelity tool:

Captured a vid of sampling a tiny diffusion model with the neural engine (A17 Pro) on my phone. Not very fast but pretty acceptable given everything happened on the iPhone locally

☁️ Tiny diffusion model on @Apple iPhone Neural Engine (ANE)

Converted one of my Tiny checkpoints into a CoreML package, and this image was generated in 3.78 seconds with memory use under 140MB on my iPhone 15 Pro.

Local, private and energy-efficient 🥂

⛅𝐓𝐢𝐧𝐲 𝐃𝐢𝐟𝐟𝐮𝐬𝐢𝐨𝐧 𝐌𝐨𝐝𝐞𝐥𝐬 I trained before are fairly compact, the left on was from a 𝟗.𝟓 𝐌𝐁 one and the right was from a 𝟐𝟐 𝐌𝐁 one. It is fun to witness how a model learns the statistics which enables generative sampling of that photographic experience.

What I always wanted ! Pure JavaScript OpenEXR I/O
Thank you @benhouston3d 🤩

[Ben Houston @benhouston3d]

HDRify, the pure JavaScript implementation of EXR, HDR, and UltraHDR Jpgs, now has its own VSCode & Cursor extensions.

Preview (with tone mapping/exposure) and convert between HDR, EXR and UltraHDR Jpgs.

Link below.

@tiraoka *ARM64* 🤞

[Garrett Johnson @garrettkjohnson]

It's been a long time coming but the latest version of three-mesh-bvh brings support for out-of-the-box Line & Point cloud BVH support! Now all your geometries can be fast 🚀

Splannequin: Freezing Monocular Mannequin-Challenge Footage with Dual-Detection Splatting

TL;DR: How to freeze a dynamic molecular scene when people inevitably move.

Contributions:
• A Novel Problem Formulation and Benchmark: We are the first to formally address synthesizing high-fidelity, freeze-time videos from monocular MC footage, providing a new benchmark and evaluation protocol.

• A Targeted Regularization Framework: We propose a novel method to identify and regularize hidden and defective Gaussians, the primary sources of temporal artifacts, anchoring them to reliable past or future states.

• State-of-the-art Performance with Zero Inference Overhead: We improve visual quality and stability in existing methods without architectural changes. As the deformation runs only once for a target instant, we achieve inference speeds exceeding 280 FPS on an RTX 4090.

The same stippling method can create some interesting depth of field effect.

[Mike Wong @artixels]

Found a Depth of Field demo code of 2.5D moving stipples; here we slide the image plane through Z.

Every cape is one bug away from becoming a scarf. 🦸‍♂️
But one scientist finally fixed it - millions of ribbons, noodles, and fabrics twisting together. Human ingenuity at its best! What a time to be alive! Full video: https://t.co/kqrnLYt7Hf

@voxagonlabs @BetterSoftwareC Finally watched your talk, very nice. Thank you for sharing 🙏

@hardmaru @icmlconf LLM engineering 😅

My talk from @BetterSoftwareC last week is up on youtube. I present my findings on thread synchronization and job systems that I learned while parallelizing the physics solver. https://t.co/sWqeAojze9
