Ye Yu, Abhimitra Meka, Mohamed Elgharib, Hans-Peter Seidel, Christian Theobalt, William A. P. Smith
2021 arXiv   pre-print
A novel relighting is then produced by modifying the illumination parameters. Our solution capture shadow using a dedicated shadow prediction map, and does not rely on accurate geometry estimation.  ...  We evaluate our technique subjectively and objectively using a new dataset with ground-truth relighting.  ...  Related Work Relighting a scene is a complex task.  ...

StyleVideoGAN: A Temporal Generative Model using a Pretrained StyleGAN [article]

Gereon Fox and Ayush Tewari and Mohamed Elgharib and Christian Theobalt
2021 arXiv   pre-print
For the spatial domain we use a pre-trained StyleGAN network, the latent space of which allows control over the appearance of the objects it was trained for.  ...  We present a novel approach to the video synthesis problem that helps to greatly improve visual quality and drastically reduce the amount of training data and resources necessary for generating videos.  ...  We trained Gereon Fox gfox@mpi-inf.mpg.de Ayush Tewari atewari@mpi-inf.mpg.de Mohamed Elgharib elgharib@mpi-inf.mpg.de Christian Theobalt theobalt@mpi-inf.mpg.de Max Planck Institute for  ...

Mohamed A. Elgharib, François Pitite, Anil Kokaram, Venkatesh Saligrama
2013 Proceedings of the 10th European Conference on Visual Media Production - CVMP '13  
As a result reflections cause many techniques to fail e.g. detection, tracking, motion estimation, etc. Recent work was proposed by Ahmed et al. [5] to detect reflections.  ...  From left; a person (foreground) superimposed on a shop indoor, a building (foreground) superimposed on white posters, pedestrians (foreground) superimposed on a red background.  ...  When viewed from a moving camera two different layers are observed each moving with a different motion.  ...

Mohamed A Elgharib, François Pitié, Anil Kokaram
2013 EURASIP Journal on Image and Video Processing  
The first is a Bayesian framework for removing two common types of degradations on video known as blotches and line scratches.  ...  Our framework is based on modeling corruption as a semi-transparent layer. This model was introduced earlier by Ahmed et al. (ICIP 2009) for the problem of blotch removal.  ...  © 2013 Elgharib et al.; licensee Springer.  ...

2019 arXiv   pre-print
We present a real-time approach for multi-person 3D motion capture at over 30 fps using a single RGB camera.  ...  This is a further key distinction from previous work that neither extracted global body positions nor joint angle results of a coherent skeleton in real time for multi-person scenes.  ...  We need a fast method that maintains identity of a detected person across frames and re-identifies it after a period of full occlusion.  ...
