First up at #UpSurge. Meet @bifrost_ai who are empowering today's creators with the computer vision tools to unleash innovation & capabilities that were previously unimaginable.
Check out their awesome #GenerativeAI video below to see it in action! 👇

@iBrews Yes it is. Animation retargeting and morph targets being buzz words that might help getting more context on how 👍

The MetaHuman Sample dataset is publicly available over at Kaggle, includes all rendering methods and some base metadata. Also includes timed speech and audio associated.

@Fishylein Both FACS dataset and this are basically making use of existent MetaHumans morph targets, the difference is that in this case is being live tracked by Openpose face module while FACS were preset poses. I don't really have a shareable script for this. Hope it helps

[Alexandre Mendes @_AllexMendes]

Face tracking and some FACS being applied just with a simple RGB webcam. Improving the "shakiness" from 3d pose estimation soon.

@lliang2003 No, not public yet.

[Alexandre Mendes @_AllexMendes]

The good result. Just needed some more smoothing around the eyes and lips.

You can even filter triangle count and etc...

Today I learned about unreal advanced search syntax…
In this case, search under MetaHumans directory filtering assets that have"body" and "f" and not "preview" in their name.
These can also be saved as collections for quick use

@tharkban I've added that as a description to the dataset. I'm aware, to an extent, and plan to fix it on a next version. Although pose itself is correct, camera to hand perspective doesn't follow asl pose standards.

Synthetic dataset for ASL Alphabet hands poses. 1K images per letter, diversity, randomization and per-finger segmentation for easier understanding.

Published a dataset sample of multiple realistic synthetic humans performing random FACS expressions. Feel free to explore it.

Web streaming UE's scene viewport, editor, PIE, and standalone. So far possible applications I've thought of are remote collaboration, teaching and eventually other cloud-streamed apps.

Published a dataset sample of highly realistic simulated humans with pixel-perfect segmentation and metadata including gaze direction. Feel free to explore it.

Can AI make graphics look realistic ? 🚗
👇Proud to announce a new work with Stephan Richter and Vladlen Koltun.
I worked on this in my internship at Intel but majority of credit is to Stephan who persisted to make it work and work robustly.

Improved the webcam face tracker. Now with a more stable head pose.
