Hello, I'm Nikita Karaev

I am a Ph. D student at Meta AI and Visual Geometry Group, University of Oxford advised by Christian Rupprecht, Natalia Neverova and Andrea Vedaldi. Before my PhD, I did an engineering program at École Polytechnique in beautiful Paris. Also, I enjoy running and exploring mountains 🏔️

CoTracker: It is Better to Track Together

Nikita Karaev, Ignacio Rocco, Benjamin Graham, Natalia Neverova, Andrea Vedaldi, Christian Rupprecht

CoTracker bridges the gap between long-term point tracking and Optical Flow by jointly tracking multiple points (pixels) throughout an entire video.

DynamicStereo: Consistent Dynamic Depth from Stereo Videos

Nikita Karaev, Ignacio Rocco, Benjamin Graham, Natalia Neverova, Andrea Vedaldi, Christian Rupprecht
CVPR 2023

We introduce Dynamic Replica, a synthetic benchmark dataset for dynamic depth-from-stereo models, and propose DynamicStereo, a temporally consistent disparity estimation model that we train on this dataset.
