Abstract
Compressive sensing (CS) is an emerging field of research with far-reaching impact on a variety of applications. For signals admitting sparse representations, CS permits collection of a significantly reduced number of measurements than required by the Shannon-Nyquist sampling theorem and provides efficient superresolution signal reconstruction. In essence, CS provides means for reducing data volume and efficient sensor deployment without a degradation in system performance. Such capabilities are highly desirable for a range of civil and military applications.

Compressive sensing (CS) is an emerging field of research with far-reaching impact on a variety of applications. For signals admitting sparse representations, CS permits collection of a significantly reduced number of measurements than required by the Shannon-Nyquist sampling theorem and provides efficient superresolution signal reconstruction. In essence, CS provides means for reducing data volume and efficient sensor deployment without a degradation in system performance. Such capabilities are highly desirable for a range of civil and military applications.

The primary objective of this special section is to concentrate the recent developments within the CS framework in a variety of imaging modalities into one place, rather than them being scattered among many sources. In so doing, we aim to promote cross-fertilization of concepts, methods, techniques, and enabling technologies across the various application areas of CS. This section includes a total of 13 contributions from researchers in academia, industry and governments. It provides a sampling of the current treatment of pressing issues in CS as applied to the following imaging modalities: (1) radar imaging, (2) video, (3) optical imaging, and (4) magnetic resonance imaging.

The topics covered in the six articles on compressive radar imaging are: joint localization of stationary and moving targets inside building structures as discussed by Qian, Ahmad, and Amin; robust sparse through-the-wall radar image reconstruction as presented by Tang, Bouzerdoum, and Phung; electromagnetic mapping of building interior layout as addressed by Lagunas et al.; target detection in multi-input multi-output compressive noise radar imaging and waveform design for ultra-wideband compressive radar as provided in articles, by Kwon, Narayanan, and Rangaswamy, and by Shastry, Narayanan, and Rangaswamy; and finally, off-the-grid target imaging in sparse ground-penetrating radar as addressed by Gurbuz, Teke, and Arikan.

The topics covered in the four articles on CS in video are reconstruction of videos from streaming compressive measurements as discussed by Park and Wakin; decoding of framewise compressed-sensed video as presented by Liu and Pados; iterative video compressed sensing as addressed by Kim and Bilgin; and finally, acquisition of compressed measurements for efficient video reconstruction using a single-pixel camera as discussed by Noor and Jacobs.

The topics covered in the two articles on compressive sensing in optical imaging are object defect detection and recognition in three-dimensional terahertz imagery as presented by Brook et al.; and compressive active underwater laser serial imaging as discussed by Ouyang et al. Finally, the article by Liu, Nutter, and Mitra addresses fast magnetic resonance imaging in a compressive sensing framework.

We hope you will enjoy reading this special section of the Journal of Electronic Imaging. We express our sincere gratitude to all of the authors and the reviewers, whose diligent efforts made this special section possible. We also greatly appreciate the immeasurable support, assistance, and guidance of the Editor-in-Chief, Dr. Gaurav Sharma, as well as the SPIE editorial staff members, throughout the process.
