Google is open-sourcing a new general purpose data compression library called Zopfli that can be used to speed up Web downloads. The Zopfli Compression Algorithm, which got its name from a Swiss bread ...

Lossy compression schemes can be based on a source model, as in the case of speech compression, or a user or sink model, as is somewhat the case in image compression. In this chapter we look at audio ...

Coding, information theory and compression provide a unified framework for quantifying, transmitting and summarising data. At its heart lies the concept of entropy, which measures the average ...

When it comes to preserving bandwidth for multichannel distribution of video, much of the discussion has centered on new compression algorithms (H.264 AVC and H.265 HEVC) that reduce bits and maintain ...

Make this your preferred source to get more updates from this publisher on Google. Google has made available online a new data compression code that it said can speed up downloads from the Internet ...

In MPEG Layer III coding the compression gain is mainly achieved through the unequal distribution of energy in the different frequency bands, the use of the psychoacoustic model, and Huffman coding.
