On some Problems of Signal and Image Processind, Analysing and Protection


  • David G. Asatryan Institute for Informatics and Automation Problems of NAS RA


Establishing the Computing Center of the National Academy of Armenia and Yerevan State University in fifties of the last century initiated the deployment of intensive scientific investigations in the area of computer science and information technologies in Armenia. Now it can be stated that the institute is an important component of E-infrastructure of Armenia, providing high level of scientific investigations and supplying numerous organizations of the republic with highly qualified specialists in the specified area. The research area of the institute includes all basic fields of computer science and information technologies. In this report we consider briefly three subjects of research and technologies, related to the signal and image processing, digital analysis and protection, carried out in the institute for last decades.
