This special issue of the EURASIP Journal of Advances in Signal Processing is intended to present innovative signal processing ideas that can be readily reproduced mainly by other researchers.

Reproducible research results become more and more an important issue as systems under investigation are growing permanently in complexity, and it becomes thus almost impossible to judge the accuracy of research results merely on the bare paper presentation.

The precise definition of reproducibility varies across disciplines, but it is often closely related to the definitions of repeatability and replicability. In a recent encyclopedia of philosophy of science, reproducibility is described as the repeatability of the process of establishing a factor of the conditions under which the same fact can be observed. In natural science, reproducibility is often related closely to the repeatability of experimental conditions and results.

We devote this special issue particularly to research results in signal processing that can be proven to be reproducible. In particular, we expect that the code and the companion data in the paper will be available by the authors at submission time to be checked as part of the review process. If the paper is accepted for publication, then the software must be provided for downloads on the publisher's webpage. Though source code is preferred, the authors must prepare a working object code.

In order to facilitate reproducible results, we expect that all code is provided to reproduce the various tables and figures in the paper. Furthermore, we expect that the code is well documented and a permanent email address as point of contact shall be provided possibly also with a permanent webpage so that fellow researchers can refer to someone if they have questions or simply report bugs they found. It would also be good to see additional testing material that was used to evaluate the correctness of the code.

In particular we like to include the following fields of signal processing:
* Signal processing in communications
* Signal processing in audio, music and speech
* Signal processing in image and video signal processing in radar, sonar, and remote sensing
* Signal processing for 3D environments
* Signal processing in emerging fields
* Multimedia signal processing

This special issue is open to all contributions. Authors are invited to submit their papers addressing signal and image processing.

Before submission authors should carefully read over the journal's Author Guidelines, which are located at http://www.hindawi.com/journals/asp/guidelines.html. Prospective authors should submit an electronic copy of their complete manuscript through the journal Manuscript Tracking System at http://mts.hindawi.com/ according to the following timetable:
