Generalized Event Cameras

no code implementations CVPR 2024 Varun Sundar, Matthew Dutson, Andrei Ardelean, Claudio Bruschini, Edoardo Charbon, Mohit Gupta

To implement our designs, we turn to single-photon sensors that provide digital access to individual photon detections; this modality gives us the flexibility to realize a rich space of generalized event cameras.

SoDaCam: Software-defined Cameras via Single-Photon Imaging

no code implementations ICCV 2023 Varun Sundar, Andrei Ardelean, Tristan Swedish, Claudio Bruschini, Edoardo Charbon, Mohit Gupta

As an added benefit, our projections provide camera-dependent compression of photon-cubes, which we demonstrate using an implementation of our projections on a novel compute architecture that is designed for single-photon imaging.

Single-Photon Structured Light

no code implementations CVPR 2022 Varun Sundar, Sizhuo Ma, Aswin C. Sankaranarayanan, Mohit Gupta

We present a novel structured light technique that uses Single Photon Avalanche Diode (SPAD) arrays to enable 3D scanning at high-frame rates and low-light levels.

[Re] Rigging the Lottery: Making All Tickets Winners

1 code implementation RC 2020 Varun Sundar, Rajat Vadiraj Dwaraknath

For a fixed parameter count and compute budget, the proposed algorithm (RigL) claims to directly train sparse networks that match or exceed the performance of existing denseto-sparse training techniques (such as pruning).

FlatNet: Towards Photorealistic Scene Reconstruction from Lensless Measurements

1 code implementation29 Oct 2020 Salman S. Khan, Varun Sundar, Vivek Boominathan, Ashok Veeraraghavan, Kaushik Mitra

Lensless imaging has emerged as a potential solution towards realizing ultra-miniature cameras by eschewing the bulky lens in a traditional camera.

Deep Atrous Guided Filter for Image Restoration in Under Display Cameras

1 code implementation14 Aug 2020 Varun Sundar, Sumanth Hegde, Divya Kothandaraman, Kaushik Mitra

In this work, we present Deep Atrous Guided Filter (DAGF), a two-stage, end-to-end approach for image restoration in UDC systems.
