In information theory, data compression, source coding, or bit-rate reduction is the process of encoding information using fewer bits than the original...

Data compression ratio, also known as compression power, is a measurement of the relative reduction in size of data representation produced by a data...

Lossless compression is a class of data compression that allows the original data to be perfectly reconstructed from the compressed data with no loss...

technology, lossy compression or irreversible compression is the class of data compression methods that uses inexact approximations and partial data discarding...

In data compression and psychoacoustics, transparency is the result of lossy data compression accurate enough that the compressed result is perceptually...

caused by the application of lossy compression. Lossy data compression involves discarding some of the media's data so that it becomes small enough to...

asymmetry, in the context of data compression, refer to the time relation between compression and decompression for a given compression algorithm. If an algorithm...

Image compression is a type of data compression applied to digital images, to reduce their cost for storage or transmission. Algorithms may take advantage...

lossless data compression algorithm that is focused on compression and decompression speed. It belongs to the LZ77 family of byte-oriented compression schemes...

LZ77 and LZ78 are the two lossless data compression algorithms published in papers by Abraham Lempel and Jacob Ziv in 1977 and 1978. They are also known...
