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 ...

This is what run-length encoding requires. Correspondingly, delta encoding followed by Huffman and/or run-length encoding is a common strategy for compressing signals. LZW compression is named after ...

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 ...

These are generally much simpler than bit-oriented formats. In the vast majority of cases, a byte-oriented format is likely to be sufficient for most general data storage needs, with bit-oriented ...

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 ...
