Passive Micron-scale Time-of-Flight with Sunlight Interferometry

no code implementations CVPR 2023 Alankar Kotwal, Anat Levin, Ioannis Gkioulekas

We introduce an interferometric technique for passive time-of-flight imaging and depth sensing at micrometer axial resolutions.

Swept-Angle Synthetic Wavelength Interferometry

no code implementations CVPR 2023 Alankar Kotwal, Anat Levin, Ioannis Gkioulekas

As in conventional synthetic wavelength interferometry, our technique uses light consisting of two narrowly-separated optical wavelengths, resulting in per-pixel interferometric measurements whose phase encodes scene depth.

Optimizing Codes for Source Separation in Color Image Demosaicing and Compressive Video Recovery

no code implementations7 Sep 2016 Alankar Kotwal, Ajit Rajwade

There exist several applications in image processing (eg: video compressed sensing [Hitomi, Y. et al, "Video from a single coded exposure photograph using a learned overcomplete dictionary"] and color image demosaicing [Moghadam, A.
