متن کاملJPEG 2000 vs. JPEG in MPEG Encoding
The MPEG-2 standard is the most used codec for video compression. This paper investigates the consequence of replacing the JPEG core system of the MPEG-2 video codec by a progressive image codec, specifically JPEG 2000, so creating a video codec (VC) that can match any desired bit rate. The quality of compressed video sequences between MPEG-2 and VC is compared. Results show that our codec impr...
متن کاملSecure JPEG 2000-JPSEC
The Joint Photographic Experts Group (JPEG) has recently rolled out a new still image coding standard called JPEG 2000. This standard integrates an efficient image compression scheme with functionalities required by multimedia applications, such as progressiveness up to lossless coding, region of interest coding, and error resiliency. Security is a concern in many applications, and therefore al...
متن کاملAn Overview of JPEG-2000
JPEG-2000 is an emerging standard for still image compression. This paper provides a brief history of the JPEG-2000 standardization process, an overview of the standard, and some description of the capabilities provided by the standard. Part I of the JPEG-2000 standard specifies the minimum compliant decoder, while Part II describes optional, value-added extensions. Although the standard specif...
متن کاملFormat for JPEG 2000 Video
This memo describes an RTP payload format for the ISO/IEC International Standard 15444-1 | ITU-T Rec. T.800, better known as JPEG 2000. JPEG 2000 features are considered in the design of this payload format. JPEG 2000 is a truly scalable compression technology allowing applications to encode once and decode many different ways. The JPEG 2000 video stream is formed by extending from a single ima...
