Compression algorithms, such as LZ77 and Huffman, analyze data for redundancies and patterns, allowing them to represent those patterns more efficiently with fewer bits.

But algorithms used on the Linux command line to compress or archive user files have to be able to reproduce the original content exactly. In other words, they have to be lossless. How is that done?

The compression technique they ended up implementing is based on the F5 algorithm that embeds binary data into JPEG files to reduce total space in the memory.

Google has released a new data compression algorithm it hopes will make the Internet faster for everyone. Dubbed Zopfli, the open-source algorithm will accelerate data transfer speeds and reduce ...

This compression may be lossless, such as in png files, or lossy, as in jpg files. Lossless photo compression works similarly to zip and rar compression: it packs data with a reversible algorithm.

MIT researchers could speed up file compression using an improved Fourier transform algorithm A group of MIT researchers believe they’ve found a way to speed up audio, video, and image ...
