I graduated with a Doctorate of Engineering (German equivalent of Ph.D.) 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!

Live Illumination Decomposition of Videos 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. [pdf]

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. [pdf], [video], [project page]

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. [pdf], [video], [project page]

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. [pdf], [video], [project page]

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. [pdf], [video], [additional video], [project page]
