Lossy Compression (Data Compression)

Description

The reduction or ideally elimination of redundancies in the original data to result in smaller required storage space is the goal of every compression scheme. There are two categories of data compression: lossy and lossless.

Lossy compression is achieved by only discarding the redundancies and out of human perception information and getting rid of those extra bits.
