JPEG2000

The next generation still image compression standard

Abstract :

Introduction 

JPEG2000 is a new image coding system that for different types of still images  bi-level gray-level color multi-component

Features

	Low bit-rate compression performance
	Lossless and lossy compression
	Large images
	Single decompression architecture
	Transmission in noisy environments
	Computer generated imagery

Compound documents
