Application of the Vector Quantization Compression Method in the Video Supervision of Maritime Systems

Iris recognition system occupies a larger and larger place in biometric identification because of its reliability. Popularity of this type of identification is growing in maritime systems, such as port security, coast guard, etc. Iris images need to be stored in databases and often sent over communication channel in large variety of biometric identification systems used in marine. Consequently, iris images should be compressed while maintaining acceptable accuracy in identification process. This paper explores advantages of Classified Vector Quantization (CVQ) compression method combined with some standard image processing methods, such as contrast, brightness, etc. Compressed iris images should differ from original images as less as possible. Experiments presented in this paper show that processed iris images are less different from original images than unprocessed iris images at the same bit rate level.
