JPEG2000 pression standard
and characteristics
Abstract
With the development of work and multimedia technologies , people need more and more images with high function and quantity , so pressive image techniques require higher performance as well as new characteristics to satisfy some special use. For this , ISO released again a new static press technique - JPEG2000 , which may e the new pression standard in the future.
JPEG2000 is to adapt to the continuous development of pression applications, the emergence of new still pression standard. JPEG2000 image coding system describes the realization of the process, of which the basic algorithm used is described and key technologies, introduced the new standard features and applications, and its performance is analyzed. With the rapid growth of multimedia applications works continues to develop, the traditional pression technology has been unable to meet the people's digital multimedia image data requirements, a more powerful and efficient superior still pression standard has been referred to the development agenda , this is a JPEG2000.
Introduction
JPEG (Joint Photographic Experts Group) is the anization for Standardization (ISO) developed under the leadership of mittee still pression standard, the first set of international still pression standard ISO 10918-1 (JPEG) is that established by mittee. As the excellent quality JPEG, so that within a few years he was a great ess, is widely used in the field of and digital cameras on the site 80% have adopted the JPEG pression standard. However, the current JPEG still pression standard, with mid-range and high-bit-rate on the rate distortion characteristics of a good, but in the context of low bit rate, there will be obvious blocking effects, its quality has e eptable . JPEG can not be provided in a single stream
