WHAT IS COMPRESSIONS IN IMAGE PROCESSING

Compression - it is reducing the physical size of information and removed the redundancy 

Compression two type 

Lossless ( No data loss )

Lossy (Some information loss ) 

Lossless example is Test , Encryption and Huffman code 

Lossy example Image , Videos , Audio 

Compression Advantage 

Less disk space 

Fast file transfer

Byte order independent 

Disadvantage 

Effect to decompression all previous data 

Lossless 

Information preserving 

Low Compression ratio 

Image without  Any data loss 

Can reproduce mathematically and identical original 

TIFF ( Tagged image file format )

Exact reconstruction is possible 

LOSSY 

Not information preserving 

High Compressions Ratio 

Can not reproduces original 

Not Mathematically but Physiological method
