Seminar on applications of image processing techniques
Realm of national security encompasses components like defence, internal security and economic security, said M.S.Vijayaraghavan, Advisor, National Technical Research Organisation (NTRO), New Delhi, here on Friday.
Inaugurating the international conference on image processing techniques and its applications at SASTRA University, Mr. Vijayaraghavan said that while in defence, adversary can be defined and strategies planned accordingly, in internal security adversary can not be defined. But one entity is common for these fields – technology.
Technologies like image processing, particularly digital image processing, play an important role in national security. In image processing, steganography, cryptography play a major role and research in these fields is called for.
Steganography is the art and science of writing hidden images in such a way that no one apart from the sender and intended recipient suspects the existence of the message.
Steganography includes the concealment of information within computer files. In digital steganography electronic communications and steganographic coding are used.
Yet another area which can be used in the field of image processing is cryptography. Modern cryptography intersects the disciplines of mathematics, computer science and electrical engineering. Application of cryptography includes ATM cards, computer passwords and electronic commerce. Modern cryptography is heavily based on mathematical theory and computer science practices.
Mr. Vijayaraghavan called for creating not only centres of excellence in various fields of science and technology in the country but also they should be centres of relevance as envisaged by former President Dr.Abdul Kalam.
There are 35 centres of excellence in the country now. There should be synergy among them to carry forward the research.
R.Ramachandran, Director, National Technical Research Organisation (NTRO), New Delhi, delivered the presidential address. S.N.Srivatsava, Registrar of SASTRA University, spoke.
