Every lens leaves a blur signature—a hidden fingerprint in every photo.

In our new #TPAMI paper, we show how to learn it fast (5 mins of capture!) with Lens Blur Fields ✨

With it, we can tell apart ‘identical’ phones by their optics, deblur images, and render realistic blurs.

Machine Learning-Based Manufacturing Cost Prediction from 2D Engineering Drawings via Geometric Features We present an integrated machine learning framework that transforms how manufacturing cost is estimated from 2D engineering drawings. Unlike traditional quotation workflows that require labor-intensiv...

Predicting manufacturing costs directly from 2D CAD drawings using XGBoost on geometric features

Yeah document parsing is cool, but what about CAD drawing parsing... (but with documents too 🥺)

Just added three.js to our landing page

Thanks for sharing, Sung!!

Picture of a stage at SIGGRAPH Asia, where we receive the Honorable Mention Award

🏆 So honored that our paper received the Honorable Mention #Award at #SIGGRAPHAsia!

I really like this paper BTW, it is about procedural #SignedDistanceFields, a simple idea to #differentiate them and thus provide #DirectManipulation ✨

lol def dont disagree with that- these days uv makes things a little better though (but still a nightmare once you have cuda extensions etc)

Added!

added!

Definitely agree wrt race conditions! Rust makes concurrency actually fun the work with

Note the “for C++-like systems programming”. Python is not a language meant for that.

Would love to be added :D

Would love to be on there as well 😃

👋 working on high throughput LLMs for data enrichment

You can definitely replace the kernel launch code with Rust / PyO3 (although I’ve never tried this myself) but the kernels themselves will still be in CUDA C++ (just runtime or compile time built by Rust)

Yep cudarc! (didn't exist the last time I considered learning Rust which was a long time ago)

(Hopefully I'll never have to find out)

To be fair maybe CMake wouldn't be so bad now with Claude

I've definitely wasted many hours of my life fighting CMake 😆

Yes the functional features are definitely very nice too! The status quo on teams I've worked on has generally unfortunately just been CMake 😭

CUDA support in Rust is pretty good these days which was also a reason why Rust was easier to adopt now! (but of course muddles the whole 'memory safety' thing which is also why I don't think that's the main feature of Rust)

Haven't built a sim engine with Rust, but specifically for concurrency code Rust feels way less scary than C++. So application might matter a bit.

Also it definitely would've taken longer for me to learn Rust if I didn't also have Claude to explain all the concepts / compiler errors for me!

Many think Rust is primarily about memory safety, but the real reason to use Rust is developer productivity (for C++-like system programming) from having a sane package manager and type system.

"MIT of the North" as they say 🤣

(made me think of this since this is what searching “towaki” on the gif search on bluesky gets me)

A year ago if I asked these LLMs about me it would have no idea. Still not entirely correct but scary it can hold this very obscure knowledge…

Yeah here's my geometry processing starter pack. I hand-picked researchers and practitioners either in geometry processing or not, and some people are definitely missing so,

Done!
