Coordinate-Based Seismic Interpolation in Irregular Land Survey: A Deep Internal Learning Approach

no code implementations21 Nov 2022 Paul Goyes, Edwin Vargas, Claudia Correa, Yu Sun, Ulugbek Kamilov, Brendt Wohlberg, Henry Arguello

Physical and budget constraints often result in irregular sampling, which complicates accurate subsurface imaging.

Beurling-Selberg Extremization for Dual-Blind Deconvolution Recovery in Joint Radar-Communications

no code implementations16 Nov 2022 Jonathan Monsalve, Edwin Vargas, Kumar Vijay Mishra, Brian M. Sadler, Henry Arguello

In this dual-blind deconvolution (DBD) problem, the receiver admits a multi-carrier wireless communications signal that is overlaid with the radar signal reflected off multiple targets.

Fast Disparity Estimation from a Single Compressed Light Field Measurement

no code implementations22 Sep 2022 Emmanuel Martinez, Edwin Vargas, Henry Arguello

Specifically, we propose to jointly optimize an optical architecture for acquiring a single coded light field snapshot and a convolutional neural network (CNN) for estimating the disparity maps.

Compressive Sensing Disparity Estimation

Joint Radar-Communications Processing from a Dual-Blind Deconvolution Perspective

no code implementations11 Nov 2021 Edwin Vargas, Kumar Vijay Mishra, Roman Jacome, Brian M. Sadler, Henry Arguello

When the radar receiver is not collocated with the transmitter, such as in passive or multistatic radars, the transmitted signal is also unknown apart from the target parameters.

Time-Multiplexed Coded Aperture Imaging: Learned Coded Aperture and Pixel Exposures for Compressive Imaging Systems

no code implementations ICCV 2021 Edwin Vargas, Julien N. P. Martel, Gordon Wetzstein, Henry Arguello

Compressive imaging using coded apertures (CA) is a powerful technique that can be used to recover depth, light fields, hyperspectral images and other quantities from a single snapshot.
