The objective of�IJCIStudies�is to report the most recent research in advanced computational intelligence paradigms, their foundations, theory and applications. Computational intelligence techniques have been successfully applied to solve problems in several fields of interest, such as biometrics, medical diagnosis, signal processing, etc. However, the potentialities of computational intelligence over traditional techniques have not been investigated adequately. The primary objective of�IJCIStudies�is to establish an effective communication channel between researchers involved in the computational intelligence area and developers who use traditional techniques to solve real-world problems, in order to create a worthwhile synergy. Particular emphasis is given to latest techniques in the fields of image processing, pattern recognition, and signal processing in general.
