What is Coding for Compression and its Types?
Coding for compression, also known as source coding, is a method of reducing the amount of data required to represent a given piece of information. It is used to reduce the size of data to be stored or transmitted and also to improve the speed with which it can be processed. Compression coding is used in digital media, telecommunications, and other industries where large volumes of data need to be processed.
Types of Compression Coding
There are several types of compression coding techniques, each with its own advantages and disadvantages. The most common types of compression coding are lossless coding, lossy coding, and hybrid coding.
Lossless compression is a method of data compression in which all the original data can be recovered from the compressed data. It is often used for archiving data and for transmitting data over a network. Lossless compression is usually more efficient than lossy compression, but it usually produces a larger file size.
Lossy compression is a method of data compression in which some of the original data is lost in the compression process. It is used for compressing audio and video data, as well as digital images. Lossy compression is generally more efficient than lossless compression, but it can produce artifacts in the compressed data.
Hybrid compression is a combination of both lossless and lossy compression techniques. It is used to achieve a balance between file size and quality. Hybrid compression is often used for compressing audio and video data and can provide better results than either lossless or lossy compression alone.
