I graduated with a Doctorate of Engineering from the Graphics, Vision and Video Group at the Max Planck Insitute for Informatics, advised by Prof. Christian Theobalt. I encourage you to talk to me about Inverse Rendering for Augmented Reality applications. Or we could talk if you are familiar with this!

Self-supervised Outdoor Scene Relighting

Y. Yu A. Meka E. Mohamed H-P. Seidel C. Theobalt W. Smith

European Conference on Computer Vision (ECCV) 2020

We propose a self-supervised approach that uses in-the-wild images collected from the internet to learn to perform fully-controllable relighting of outdoor scenes from a single input image.

A. Meka M. Shafiei M. Zollhöfer C. Richardt C. Theobalt

arXiv 2019

We propose the first approach for the decomposition of a monocular color video into direct and indirect illumination components in real-time.

Deep Reflectance Fields - High-Quality Facial Reflectance Field Inference From Color Gradient Illumination

A. Meka C. Haene R. Pandey M. Zollhöfer S. Fanello G. Fyffe A. Kowdle X. Yu J. Busch J. Dourgarian P. Denny S. Bouaziz P. Lincoln M. Whalen G. Harvey J. Taylor S. Izadi A. Tagliasacchi P. Debevec C. Theobalt J. Valentin C. Rhemann

ACM Transactions on Graphics 2019 (TOG) - Proc. SIGGRAPH

We present the first approach to relight dynamic facial performances at high resolutions using a learnt 4D reflectance field model, generalizing to novel identities, expressions, and viewpoints.

Live Intrinsic Material Estimation

A. Meka M. Maximov M. Zollhöfer A. Chatterjee H.P. Seidel C. Richardt C. Theobalt

Computer Vision and Pattern Recognition 2018 (CVPR) - Spotlight Paper

We present the first approach for real-time material estimation for general object shapes that only requires a single color image as input, enabling live photo-realistic material transfer from real to virtual objects.

Live User-Guided Intrinsic Video For Static Scenes

A. Meka G. Fox M. Zollhöfer C. Richardt C. Theobalt

IEEE Transactions on Visualization and Computer Graphics 2017 (TVCG) - presented at ISMAR 2017

We present a novel technique to acquire reflectance-fused-geometry enhanced with live user-guidance for a static scene, enabling AR applications like live photorealistic scene relighting.

Live Intrinsic Video

A. Meka M. Zollhöfer C. Richardt C. Theobalt

ACM Transactions on Graphics 2016 (TOG) - Proc. SIGGRAPH

We present a novel variational approach to tackle the underconstrained intrinsic video decomposition problem at real-time frame rates, enabling on-line processing of live video footage.
