AI/SLAM Researcher

Biography

Hi! My name is Jan Czarnowski, I am a PhD Student at Imperial College London under the supervision of Andrew Davison. Prior to that I led a team of robotics researchers in PIAP, Warsaw. My research focuses on integrating Deep Learning with Dense Visual SLAM in order to push the boundaries of spatial perception with a single camera. I enjoy building systems that work in real-time and produce good-looking 3D visualisations and probably spend too much time on computer games.

CodeSLAM - Learning a Compact, Optimisable Representation for Dense Visual SLAM

Joint work with Michael Bloesch on learning a compact representation for depth maps. We showed that it is possible to use the latent representation learned by a modified auto-encoder network as an alternative manifold for optimization. We have demonstrated a simple SLAM system using the proposed method that is able to reconstruct scenes where conventional methods fail.

This work has received the Best Paper Honorable Mention award at CVPR 2018.

Semantic Texture for Robust Dense Tracking

This work demonstrates that it is possible to perform dense whole-image alignment on feature activations coming from an off-the-shelf CNN classifier. These features form a pyramid of varying semantic levels which, optimized in a coarse-to-fine manner, allows for much more robust camera tracking.

LS-Net: Learning to Solve Nonlinear Least Squares for Monocular Stereo

Sum-of-squares objective functions are very popular in computer vision algorithms. However, these objective functions are not always easy to optimize. The underlying assumptions made by solvers are often not satisfied and many problems are inherently ill-posed. In this paper, we propose LS-Net, a neural nonlinear least squares optimization algorithm which learns to effectively optimize these cost functions even in the presence of adversities.
