As such, it lends itself to applications that require high-quality images despite limitations on storage or transmission bandwidths.Īn important feature of systems based on JPEG 2000 is the ability to extract a variety of resolutions, components, areas of interest, and compression ratios from a single JPEG 2000 code stream. JPEG 2000 is the only standard compression scheme that provides for both lossless and lossy compression. Standards are required to ensure interoperability.

Compression is defined as lossless if full recovery of the original is available from the channel without any loss of information otherwise, it is lossy.

When transmitting or storing picture information, compression must be employed to maintain picture resolution while making best use of limited channel bandwidth. With brief comparisons to other compression standards, this article is primarily intended to highlight some of the often misunderstood and rarely mentioned potential-become-actual benefits of JPEG 2000. Its architecture is useful for many diverse applications, including Internet image distribution, security systems, digital photography, and medical imaging.Ī lot of confusion exists as to what JPEG 2000 is and how it compares with other compression standards such as MPEG (Moving-Picture Experts Group) -2, MPEG-4, and the earlier JPEG.

The PDF combines three technologies: A subset of the PostScript page description programming language, for generating the layout and graphics. A JPEG XR file contains image data, optional alpha channel data, metadata, optional XMP metadata stored as RDF/XML, and optional Exif metadata, in IFD tags. It is a TIFF-like format using a table of Image File Directory (IFD) tags. One file container format that can be used to store JPEG XR image data is specified in Annex A of the JPEG XR standard. Each PDF file encapsulates a complete description of a fixed-layout flat document, including the text, fonts, graphics, and other information needed to display it.

The Portable Document Format (PDF) is a file format used to present documents in a manner independent of application software, hardware, and operating systems. It supports both lossy and lossless compression, and is the preferred image format for Ecma-388 Open XML Paper Specification documents. JPEG XR (JPEG extended range) is a still-image compression standard and file format for continuous tone photographic images, based on technology originally developed and patented by Microsoft under the name HD Photo.
