Many methods of lossy compression have been developed; however, a family of techniques called transform compression has proven the most valuable. The best example of transform compression is embodied ...

This Sweet Snippet will show you how easy it can be to perform compression/decompression between data buffers in memory using the zlib library. We will go the easy ...

Compression is performed by a program that uses a formula or algorithm to determine how to shrink the size of the data. For instance, an algorithm may represent a string of bits-- or 0s and 1s -- with ...

Hardware and software compression is transparent to applications and storage hardware. It uses an algorithm to reduce the size of files by eliminating redundant bits. However, if the files have been ...

Images transmitted over the world wide web are an excellent example of why data compression is important. Suppose we need to download a digitized color photograph over a computer's 33.6 kbps modem. If ...
