What kind of coding?
There are compression codes, text codes, speech codes, data codes too many
Let's say compression:
Lossless compression encoding types
Huffman coding
arithmetic coding
run coding
Lempel zev code
(2) lossy compression coding types
Predictive coding: DPCM, motion compensation frequency domain method: text transform coding (such as DCT), subband coding
Spatial domain method: statistical block coding
Model method: fractal coding, model-based coding
Based on importance: filtering, subsampling, bit allocation, vector quantization
Information compression methods, also known as lossy compression, distortion degree coding or entropy compression coding
