Enlightening lives, growing connectivity around the creation, that’s the boundless promise offered by data driven technology. Images and videos are a part of life, even at technology, at the stake of privacy. This is indeed required for application as well as security purpose. An image may consist a lot of information or sometimes absolutely nothing. Making use of high-speed machines such as computers can make things easy, but alone a computer can do nothing. A computer can achieve such a skill to extract features using a key technology named” Machine Learning”. This paper specifically features a way in which defence systems can make use of this technology for security and surveillance purpose.
