In this article the authors propose the neural network (NN) classifier for identification of brain perfusion abnormality type and its localization in CBF and CBV dynamic brain perfusion maps. The approach is based on comparison of average values of CBF or CBV (obtained for healthy brain) with mean CBF or CBV values measured in symmetric regions of interests (ROI) in left and right hemisphere for diagnosed...
Identity requirements in information systems can be satisfied by the integration of biometric technologies with cryptography algorithms. In this field, one of the most important areas is the generation of strong cryptographic keys produced from many kinds of biometrics. This paper describes some solutions within this scope focusing on an efficient approach to generating cryptographic keys from visual...
This study presents new classes of cognitive categorization systems, with particular emphasis on one selected system class: UBIAS (Understanding Based Image Analysis Systems) used to analyze images. The purpose of defining new classes of cognitive categorization systems is to conduct an in-depth analysis of various kinds of data with particular attention to the semantic/meaning contents of the data...
