File compression is an incredible technological breakthrough that has made modern computing, streaming, and data storage ...

We will describe the operation of JPEG to illustrate how lossy compression works. We have already discussed a simple method of lossy data compression, coarser sampling and/or quantization (CS&Q in ...

Lossy compression is never used for business data and text, which demand a perfect restoration (see lossless compression). See data compression, codec examples, JPEG, MPEG and MP3.

Most of the commonly used compression algorithms are lossy and do a fine job of recreating the data for general purpose surveillance needs. Examples include MPEG4 and H.264.

Lossless data-compression programs search through documents for redundant or repetitive data and then encode it. For example, a text document may contain 200 empty spaces, 100 instances of the ...

With lossless compression, files are reduced in size without the loss of data. However, lossless compression does not usually achieve the same file size reduction as lossy compression.

Lossless or lossy: If you have big data, know what type of compression to use Your email has been sent Illustration: Lisa Hornung/iStockPhoto Must-read big data coverage Why the Database Market ...

Lossless compression processes audio files in a way that the size is reduced by the quality is still intact. In Lossy compression, the audioquality gets compromised.

Lossy compression methods are in fact quite useful. JPEG compression, for example, is a good example of discarding data that isn’t readily perceived by humans to make a smaller file, but that ...

In this podcast, Franck Cappello from Argonne describes EZ, an effort to effort to compress and reduce the enormous scientific data sets that some of the ECP applications are producing. "There are ...
