A compression ratio of at least 50:1 is needed to get 1080i video into a 20 Mbit/s MPEG transport stream. Uses. The data compression ratio can serve as a measure of the complexity of a data set or signal. In particular it is used to approximate the algorithmic complexity. It is also used to see how much of a file is able to be compressed ...
Lossless compression. Lossless compression is a class of data compression that allows the original data to be perfectly reconstructed from the compressed data with no loss of information. Lossless compression is possible because most real-world data exhibits statistical redundancy. [1] By contrast, lossy compression permits reconstruction only ...
High Efficiency Video Coding (HEVC, ITU-T H.265) [14] is an encoding format for graphic data, first standardized in 2013. It is the primarily used and implied default codec for HEIF as specified in the normative Annex B to ISO/IEC 23008-12 HEVC Image File Format . While not introduced formally in the standard, the acronym HEIC (High-Efficiency ...

Researchers further estimated that the statin recommendations for U.S. adults would drop from 45.4 million to 28.3 million with a change from PCEs to PREVENT equations. They also noted that many ...

One-way compression function. In cryptography, a one-way compression function is a function that transforms two fixed-length inputs into a fixed-length output. [1] The transformation is "one-way", meaning that it is difficult given a particular output to compute inputs which compress to that output. One-way compression functions are not related ...
