IMAGE & VIDEO COMPRESSION WITH RATE DISTORTION APPROACH: A REVIEW

Preeti ., Gitanjli Pandove

Abstract


In this paper, a rate distortion approach is studied to solve the optimization purpose. Now a day, digital video compression technique is most popular for cost reduction. Many applications such as digitized music or internet broadcasting the movie, provided by the digital video industry cannot be forgotten. These attributes of digital video provides continue progression in compression technology & improvement on different media storage or audio / video service streaming. A RDO(Rate distortion optimization) technique is an optimization technique which involves diamond and exhaustive search. An exhaustive search process is involved to determine the optimal quantized transform coefficient, used in block code. The computational cost of exhaustive search quantization is more expensive than conventional quantization.
