A typical data acquisition system takes periodic samples of a signal, image, or other data,
often at the so-called Nyquist/Shannon sampling rate of two times the data bandwidth in …

Method and apparatus for compressed sensing yields acceptable quality reconstructions of
an object from reduced numbers of measurements. A component x of a signal or image is …

(57) ABSTRACT A dictionary at least partially spans a set of discrete q-length signals. The
atoms of the dictionary are eigenvectors of a representation of a commutative subgroup of a …

Data series are stored at multiple resolutions in a computer readable data storage medium.
In particular, time series data values of the data series are received with associated times …

Radar interferograms provide a map of the phase difference between the reference and
repeat acquisitions modulo 2π. Under ideal conditions, the phase can be unwrapped to …

A method and system for reconstructing random samples taken across multiple sensors of a
sensor array, so that each sensor's output is reconstructed. The samples are processed …

Methods and systems for recovering corrupted/degraded images using approximations
obtained from an ensemble of multiple sparse models are disclosed. Sparse models may …

In general, techniques are described for transitioning an ambient higher order ambisonic
coefficient. A device comprising a memory and a processor may be configured to perform …

Method for reducing the time needed to perform geophysical inversion by using
simultaneous encoded sources in the simulation steps of the inversion process. The …

Method and system for more efficient checkpointing strategy in cross correlating (316) a
forward (328) and backward (308) propagated wave such as in migrating (326) or inverting …
