The growing availability and widespread use of digital multimedia information and personal wireless communication devices have motivated development of several video compression standards over the past two decades. H.264/AVC (advanced video coding) is the newest international video coding standard approved by ITU-T as Recommendation H.264 and by ISO/IEC as(More)
Entropy encoding is a term referring to lossless coding technique that replaces data elements with coded representations. Entropy encoding in combination with the transformation and quantization results in significantly reduced data size. For any conventional multimedia coding, entropy encoding is a bit assigning and lossless module. Since entropy encoding(More)
A biometric system uniquely identifies and authenticates humans based on their physical or behavioural features. Iris recognition is one of the most reliable methods of biometric authentication that recognizes a person by pattern of the iris. No two irises are alike-not between identical twins, or even between the left eye and the right eye of the same(More)
Fingerprint recognition refers to the automated method of verifying a match between two human fingerprints. Fingerprints are one of many forms of biometrics used to identify an individual and verify their identity. The non-changeability of Fingerprints during the human life span and the uniqueness of each individual's fingerprints are the basis for using(More)
As there is an enormous development and escalation in the field of computing technologies for the biometric based systems. Hence, they have become more convenient to be embedded to a variety of devices and also they are affordable to a very less cost and are used in daily life say, laptops, mobiles, key pads, palmtops and etc., and hence allowing these(More)
