Researchers in Slovakia benchmarked five lossless compression algorithms directly on an STM32 microcontroller, revealing ...

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 ...

A new study in Multimedia Tools and Applications presents two hybrid image compression schemes, HLL1 and HLL2, that combine ...

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 ...

Erasure coding, deduplication and compression are three distinctly different and independent concepts, but all three can help conserve costly storage capacity. Generally, RAID techniques add ...

The Layer II coder provides a higher compression rate by making some relatively minor modifications to the Layer I coding scheme. These modifications include how the samples are grouped together, the ...
