- Image compression - Wikipedia
Image compression is a type of data compression applied to digital images, to reduce their cost for storage or transmission Algorithms may take advantage of visual perception and the statistical properties of image data to provide superior results compared with generic data compression methods which are used for other digital data
- bzip2 - Wikipedia
bzip2 is a free and open-source file compression program that uses the Burrows–Wheeler algorithm It only compresses single files and is not a file archiver It relies on separate external utilities such as tar for tasks such as handling multiple files, and other tools for encryption, and archive splitting bzip2 was initially released in 1996 by Julian Seward It compresses most files more
- Data compression ratio - Wikipedia
Data compression ratio, also known as compression power, is a measurement of the relative reduction in size of data representation produced by a data compression algorithm
- Deflate - Wikipedia
Deflate64, specified by PKWARE, is a proprietary variant of Deflate It's fundamentally the same algorithm What has changed is the increase in dictionary size from 32 KB to 64 KB, an extension of the distance codes to 16 bits so that they may address a range of 64 KB, and the length code, which is extended to 16-bit, so that it may define lengths of three to 65,538 bytes [6] This leads to
- Lossless compression - Wikipedia
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
- Disk compression - Wikipedia
A disk compression software utility increases the amount of information that can be stored on a hard disk drive of given size Unlike a file compression utility, which compresses only specified files—and which requires the user to designate the files to be compressed—an on-the-fly disk compression utility works automatically through
- Group 4 compression - Wikipedia
G4 compression would actually increase the file size on this type of image G4 typically achieves a 20:1 compression ratio [citation needed] For an 8 5"×11" page scanned at 200 DPI, this equates to a reduction from 467 5 kB to 23 4 kB (95% compression ratio)
- Data compression - Wikipedia
Data compression aims to reduce the size of data files, enhancing storage efficiency and speeding up data transmission K-means clustering, an unsupervised machine learning algorithm, is employed to partition a dataset into a specified number of clusters, k, each represented by the centroid of its points
