CHAPTER -1 INTRODUCTION The outbreak of digital image processing in 1920’s has revolutionalised the communication process [l]. The images were the first language used by the humans for interaction. The images in the form of pictures were carved on stone which became the first language for communication and these carvings were available for the future generation. With the technical advancements in recent times; image processing techniques has became an important part of the communication system. From
CHAPTER 1 INTRODUCTION TO FACE RECOGNITION 1.1. BIOMETRICS A biometric system is a technological system that uses information about a person to identify that person. Biometric systems rely on specific data about unique biological traits in order to work effectively. A biometric system will involve running data through algorithms for a particular result, usually related to a positive identification of a user or other individual. We all have unique physiological
rather than theorists: we want to know how to apply the theory to the problem rather than just acquire a deep understanding of the theory. Our goal, then, is to be multi-disciplinary but practical. We concentrate particularly on computer science, psychology and cognitive science as core subjects, and on their application to design; other disciplines are consulted to provide input where
of appearance biometric is its non-intrusive nature. Therefore, face is one of the most compatible biometrics for oversight applications. Face perception is necessity in biometrics, often as a part of facial recognition system. It is also used in video surveillance and human electronic computer interface. Some novel digital cameras custom face detection for auto focus. Face detection is an electronic computer technology that limits the locations and sizes of earthborn face in arbitrary conception
pictures, videos and words. Pictures are superior to words in inducing evaluative responses. The written messages in words are called ‘supers’. The supers should be highly imagery and use positive sentences. This images represent the brand. John R.Rossiter(1982) It covers guidelines for the effective use of visual content in: general advertising, print advertising, and TV advertising. The study reveals that the Visual content warrants relatively more advertiser attention than verbal content, color can
An optimal realization of heterodyne receiver for SFCW UWB radar system Damodar V Kadaba1, SA Subhan1, VK Bansal1, Subhadra Singh1, Gowtham G2 1 Central Research Lab, BEL, Bangalore – 560013, 2D&E (Military Radar), BEL, Bangalore-560013 Abstract Realization of a heterodyne receiver for step frequency continuous wave (SFCW) through wall radar (TWR) is discussed in this paper. As the Doppler bandwidth of signals reflected from slow moving objects such as human beings illuminated by SFCW TWR sensor
The problem with proving properties of protocols under other schemes is that the mathematics is extremely complex for the RSA, and there is no sound mathematical basis for the DES. Much research is under way at this time in the field of protocol analysis and verification, and it is likely that once this field stabilizes, cryptographic protocols will follow
