2014 Journal of digital imaging  
bandwidth requirements needed for archival and communication of related data, preferably by employing lossless compression methods.  ...  The decimated coefficients are compressed in parallel using embedded block coding with optimized truncation of the embedded bit stream.  ...  Thus, adding a bit plane gives a better approximation. If a bit on the nth bit plane on an m-bit data set is set to 1, it contributes a value of 2 (m−n) ; otherwise, it contributes nothing.  ...

Compressing Compound Documents [chapter]

Ricardo L. de Queiroz
2006 Signal Processing and Communications  
In this chapter we introduce the basic methods for the compression of documents in raster format that may contain a mixture of text, graphics and pictures.  ...  JPEG 2000's JPM profile is discussed as a framework for general multipage multilayer document compression.  ...  Furthermore the mask plane does not spend too many bits in MRC anyways, so that JP2 is a very adequate substitute for any other binary coder in a JPM context.  ...

Lossless and Near-Lossless Audio Compression Using Integer-Reversible Modulated Lapped Transforms

Henrique S. Malvar
2007 2007 Data Compression Conference (DCC'07)  
The codec also supports a near-lossless mode, which allows for an extra factor of two in compression without noticeable distortions.  ...  Its compression performance matches those of state-of-the-art predictive codecs, and it has the advantage that its compressed bitstream contains frequency-domain data that can be used for applications  ...  Compression in the transform domain allows the bitstream to be quickly decoded to obtain frequency-domain data, which can speed up applications such as search, identification, visualization, and transcoding  ...
