Event Cameras Meet SPADs for High-Speed, Low-Bandwidth Imaging

no code implementations17 Apr 2024 Manasi Muglikar, Siddharth Somasundaram, Akshat Dave, Edoardo Charbon, Ramesh Raskar, Davide Scaramuzza

Traditional cameras face a trade-off between low-light performance and high-speed imaging: longer exposure times to capture sufficient light results in motion blur, whereas shorter exposures result in Poisson-corrupted noisy images.

DecentNeRFs: Decentralized Neural Radiance Fields from Crowdsourced Images

no code implementations19 Mar 2024 Zaid Tasneem, Akshat Dave, Abhishek Singh, Kushagra Tiwary, Praneeth Vepakomma, Ashok Veeraraghavan, Ramesh Raskar

It learns photorealistic scene representations by decomposing users' 3D views into personal and global NeRFs and a novel optimally weighted aggregation of only the latter.

SUNDIAL: 3D Satellite Understanding through Direct, Ambient, and Complex Lighting Decomposition

no code implementations24 Dec 2023 Nikhil Behari, Akshat Dave, Kushagra Tiwary, William Yang, Ramesh Raskar

3D modeling from satellite imagery is essential in areas of environmental science, urban planning, agriculture, and disaster response.

ORCa: Glossy Objects As Radiance-Field Cameras

no code implementations CVPR 2023 Kushagra Tiwary, Akshat Dave, Nikhil Behari, Tzofi Klinghoffer, Ashok Veeraraghavan, Ramesh Raskar

By converting these objects into cameras, we can unlock exciting applications, including imaging beyond the camera's field-of-view and from seemingly impossible vantage points, e. g. from reflections on the human eye.

Solving Inverse Computational Imaging Problems using Deep Pixel-level Prior

1 code implementation27 Feb 2018 Akshat Dave, Anil Kumar Vadathya, Ramana Subramanyam, Rahul Baburajan, Kaushik Mitra

On the other hand, a more flexible approach would be to learn a deep generative model once and then use it as a signal prior for solving various inverse problems.

Compressive Image Recovery Using Recurrent Generative Model

no code implementations13 Dec 2016 Akshat Dave, Anil Kumar Vadathya, Kaushik Mitra

Reconstruction of signals from compressively sensed measurements is an ill-posed problem.
