In this chapter, data compression as it relates to multimedia information is studied from the point of view of lossless algorithms, where the input data is essentially exactly recoverable from the compressed data. Lossy algorithms, for which this is not the case, are presented in Chap. 8. ...

Entropy definition is to identify often occurring symbols in the data stream with shortcode wordsin the compressedbit stream. Entropy coding used with some lossycompression algorithmsi.e.JPEG. It reduces number of bits produced from quantizer’s output for more compression. As previously mentioned, ...
introduce a two phase steganography application that allows the user to first compress the information into ASCII form using our novel compression technique (compression technique utilizing reference points coding) then embed the information into the carrier using least significant bit (LSB) algorithms. ...
In31, it adopted a method that combines super-spatial structure prediction with interframe coding to achieve compression effect. There are also some algorithms not specially designed for medical image compression32,33,34,35, which can be applied due to their generality. The image compression ...
In many applications and protocols, the number of usable characters is limited. Base64 or other similar algorithms are widely used to encode the binary data into a printable representation. But base64 itself can¿t compress data, contrarily, it inflates the binary data by 33%. This paper...
However, little is known about optimal or near optimal methods for lossless compression of strings generated by sources that are not stationary ergodic. We present a number of asymptotically efficient algorithms that address, at least from the theoretical point of view, optimal lossless compression of...
Lossless Image Compression LOCO-R Algorithm for 16 bit Image - Ramteke, Rawat - 2011 () Citation Context ...uality multimedia data in a given small storage. This branch of image compression has achieved numerous inventions during last few decades. Some of the algorithms deal with an image in...
Image coding (or compression) is an important application that has benefited significantly from the wavelet theory. Lossless image coding using wavelet decomposition is the main focus of this dissertation. Specific contributions involve design of algorithms, the development of criteria for selection of ...
In continuous-tone mode, context modeling and prediction are employed involving mostly integer arithmetic and simple logic in a conceptually sophisticated scheme. Both the encoding and decoding techniques are suitable for sequential and progressive transmission, although different specific algorithms may be ...
