Passive Micron-scale Time-of-Flight with Sunlight Interferometry
Alankar Kotwal, Anat Levin, Ioannis Gkioulekas
We introduce an interferometric technique for passive time-of-flight imaging and depth sensing at micrometer axial resolutions. Our technique uses a full-field Michelson interferom…
Swept-Angle Synthetic Wavelength Interferometry
Alankar Kotwal, Anat Levin, Ioannis Gkioulekas
We present a new imaging technique, swept-angle synthetic wavelength interferometry, for full-field micron-scale 3D sensing. As in conventional synthetic wavelength interferometry,…
Optimizing Matrices For Compressed Sensing Using Existing Goodness Measures: Negative Results, And An Alternative
Alankar Kotwal, Ajit Rajwade
The bound that arises out of sparse recovery analysis in compressed sensing involves input signal sparsity and some property of the sensing matrix. An effort has therefore been mad…
Optimizing Codes for Source Separation in Color Image Demosaicing and Compressive Video Recovery
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 di…
