ISSPA 2007 marks the 20th anniversary of launching the first ISSPA in 1987 in Brisbane, Australia. Since its inception, ISSPA has provided, through a series of 8 symposia, a high quality forum for engineers and scientists engaged in research and development of Signal and Image Processing theory and applications. Effective 2007, ISSPA will extend its scope to add the new track of information sciences. Hence, the intention that the previous full name of ISSPA is replaced after 2007 by the following new full name: International Conference on Information Sciences, Signal Processing and their Applications. ISSPA is an IEEE indexed conference. ISSPA 2007 will be organized by three prominent institutions located in Sharjah in the United Arab Emirates: University of Sharjah, American University of Sharjah, and Etisalat University College. The regular technical program will run for three days along with an exhibition of signal processing and information sciences products. In addition, tutorial sessions will be held on the first day of the symposium. Papers are invited in, but not limited to, the following topics: 1.Filter Design Theory and Methods 2.Multirate Filtering & Wavelets 3.Adaptive Signal Processing 4.Time-Frequency/Time-Scale Analysis 5.Statistical Signal & Array Processing 6.Radar & Sonar Processing 7.Speech Processing & Recognition 8.Fractals and Chaos Signal Processing 9.Signal Processing in Communications 10.Signal processing in Networking 11.Multimedia Signal Processing 12.Nonlinear signal processing 13.Biomedical Signal and Image Processing 14.Image and Video Processing 15.Image Segmentation and Scene Analysis 16.VLSI for Signal and Image Processing 17.Cryptology, Steganography, and Digital Watermarking 18.Image indexing & retrieval 19.Soft Computing & Pattern Recognition 20.Natural Language Processing 21.Signal Processing for Bioinformatics 22.Signal Processing for Geoinformatics 23.Biometric Systems and Security 24.Machine Vision 25.Data visualization 26.Data mining 27.Sensor Networks and Sensor Fusion 28.Signal Processing and Information Sciences Education 29.Others Perspective authors are invited to submit *full length* (four pages) papers for presentation in any of the areas listed above (indicate area in your submission).
