Ilya Chugunov

I'm a PhD student in the computer science program at Princeton University. I work in the Princeton Computational Imaging Lab, advised by Professor Felix Heide, and have been gratefully awarded an NSF graduate research fellowship. I completed my bachelor's in electrical engineering and computer science at UC Berkeley.

I'm interested in the end-to-end optimization of imaging pipelines, beginning at modeling signal collection and continuing through to feature extraction and high-level scene understanding tasks. From MRIs to Time-of-Flight cameras, I love getting hands-on with real devices and making the most of inevitably noisy data.

Mask-ToF: Learning Microlens Masks for Flying Pixel Correction in Time-of-Flight Imaging
Ilya Chugunov, Seung-Hwan Baek, Qiang Fu, Wolfgang Heidrich, Felix Heide
Conference on Computer Vision and Pattern Recognition (CVPR), 2021

Flying pixels are pervasive depth artifacts in time-of-flight imaging, formed by light paths from both an object and its background connecting to the same sensor pixel. Mask-ToF jointly learns a microlens-level occlusion mask and refinement network to respectively encode and decode geometric information in device measurements, helping reduce these artifacts while remaining light efficient.

Self-Contained Jupyter Notebook Labs Promote Scalable Signal Processing Education
Dominic Carrano, Ilya Chugunov, Jonathan Lee, Babak Ayazifar,
6th International Conference on Higher Education Advances, 2020

Jupyter Notebook labs can offer a similar experience to in-person lab sections while being self-contained, with relevant resources embedded in their cells. They interactively demonstrate real-life applications of signal processing while reducing overhead for course staff.

Abstract: Multiscale Low-Rank Matrix Decomposition for Reconstruction of Accelerated Cardiac CEST MRI
Ilya Chugunov, Wissam AlGhuraibawi, Kevin Godines, Bonnie Lam, Frank Ong, Jonathan Tamir, Moriel Vandsburger,
28th Annual Meeting of International Society for Magnetic Resonance in Medicine (ISMRM), 2020

Leveraging sparsity in the Z-spectrum domain, multi-scale low rank reconstruction of cardiac chemical exchange saturation transfer (CEST) MRI can allow for 4-fold acceleration of scans while providing accurate Lorentzian line-fit analysis.

Duodepth: Static Gesture Recognition Via Dual Depth Sensors
Ilya Chugunov Avideh Zakhor,
IEEE International Conference on Image Processing (ICIP), 2019

Point cloud data integrated from two structured light sensors for gesture recognition implicitly via a 3D spatial transform network can lead to improved results as compared to iterative closest point (ICP) registered point clouds.

Inspection Route Optimization
Bernard Gendron, Vidal Thibaut, et al.
Eighth Montréal Industrial Problem Solving Workshop, 2017

Property inspection routes can be formulated into graph optimization problem, decomposed into weekly/yearly constraints for reduction to team orienteering problem (TOP).


I love teaching and am always looking for new ways to convey information and foster learning; be that in lectures, office hours, or even just work meetings. Feel free to steal our signal processing lab exercises for your classes or personal education (and contribute to them if you can, some of those figures can definitely be improved c:).
