Definitions for "lossy compression"
The compression of binary data into a form which, when it is re-expanded, has most, but not all, of the original information. It is used primarily for compression of images and sounds, and is designed to provide a high degree of compression at the cost of a slight loss of data. It is expemplified by the JPEG compression standard. Images compressed by a lossy compression algorithm are re-expanded into an image close, but not identical to the original image; the difference between the original and the reconstructed image may be imperceptible to normal viewing by the eye.
A type of compression that deliberately sacrifices some of the original data in return for much higher compression ratios than those achievable with lossless techniques.
A compression algorithm that removes some data, to reduce the file size, while preserving the sound or image. Data that is removed is lost, thus altering the original image permanently.
