Modern digital cameras employ silicon focal plane array (FPA) image sensors featuring
millions of pixels. However, it is possible to make a camera that only needs one pixel. In …

Conventional approaches to sampling signals or images follow Shannon's theorem: the
sampling rate must be at least twice the maximum frequency present in the signal (Nyquist …

This survey highlights the recent advances in algorithms for numerical linear algebra that
have come from the technique of linear sketching, whereby given a matrix, one first …

This first chapter formulates the objectives of compressive sensing. It introduces the
standard compressive problem studied throughout the book and reveals its ubiquity in many …

This paper develops a mathematical theory of super‐resolution. Broadly speaking, super‐
resolution is the problem of recovering the fine details of an object—the high end of its …

Speech Emotion Recognition (SER) has emerged as a critical component of the next
generation of human-machine interfacing technologies. In this work, we propose a new dual …

In many applications, the observations can be represented as a signal defined over the
vertices of a graph. The analysis of such signals requires the extension of standard signal …

The time-frequency and time-scale communities have recently developed a large number of
overcomplete waveform dictionaries---stationary wavelets, wavelet packets, cosine packets …

This paper considers the model problem of reconstructing an object from incomplete
frequency samples. Consider a discrete-time signal f/spl isin/C/sup N/and a randomly …
