The purpose of SIGMAP 2014, the International Conference on Signal Processing and Multimedia Applications, is to bring together researchers, engineers and practitioners interested on information systems and applications in the context of Signal Processing, including theory and practice in the field of telecommunications, image, video, audio, biometrics, etc., and Multimedia Applications related to representation, storage, authentication and communication of multimedia information. The signal processing field, when combined with multimedia information encompasses a large number of research topics and emerging applications. A list of relevant topics is provided below, though many other topics could be listed. Ideas on how to analyse and apply signal processing techniques to solve problems involving multimedia information and technology, either in the scope of R&D projects, engineering or business applications, are welcome. Papers describing new methods or technologies, advanced prototypes, systems, tools and techniques and general survey papers indicating future directions are also encouraged. Papers describing original work are invited in any of the areas listed below. Accepted papers, presented at the conference by one of the authors, will be published in the Proceedings of SIGMAP, with an ISBN. Acceptance will be based on quality, relevance and originality. Both full research reports and work-in-progress reports are welcome. There will be both oral and poster sessions. The best papers will be selected to appear either in an international journal or in a book to be published by Springer-Verlag. Special sessions, case-studies and tutorials dedicated to technical/scientific topics related to the main conference are also envisaged: researchers interested in organizing a special session, companies interested in presenting their products/technology or researchers interested in holding a tutorial are invited to contact the conference secretariat.
