Sensing increased image resolution using aperture masks
We present a technique to construct increased-resolution images from multiple photos taken without moving the camera or the sensor. Like other super-resolution techniques, we capt...

Reinterpretable Imager: Towards Variable Post-Capture Space, Angle and Time Resolution in Photography
We describe a novel multiplexing approach to achieve tradeoffs in space, angle and time resolution in photography. We explore the problem of mapping useful subsets of time-varying...

Compressive sensing in through-the-wall radar imaging
High resolution through-the-wall radar imaging (TTWRI) demands wideband signals and large array apertures. Thus a vast amount of measurements is needed for a detailed reconstructi...
