JPEG 2000 has been published as an ISO standard, ISO/IEC 15444. Another difference, in comparison with JPEG, is in terms of visual artifacts: JPEG 2000 only produces ringing artifacts, manifested as blur and rings near edges in the image, while JPEG produces both ringing artifacts and 'blocking' artifacts, due to its 8×8 blocks. However, as a consequence of this flexibility, JPEG 2000 requires codecs that are complex and computationally demanding. By ordering the codestream in various ways, applications can achieve significant performance increases. The codestream obtained after compression of an image with JPEG 2000 is scalable in nature, meaning that it can be decoded in a number of ways for instance, by truncating the codestream at any point, one may obtain a representation of the image at a lower resolution, or signal-to-noise ratio – see scalable compression. While there is a modest increase in compression performance of JPEG 2000 compared to JPEG, the main advantage offered by JPEG 2000 is the significant flexibility of the codestream. However, JPEG 2000 is still not widely supported in web browsers (other than Safari) as of 2022, and hence is not generally used on the World Wide Web. JPEG 2000 technology was selected as the video coding standard for digital cinema in 2004. The standard could be adapted for motion imaging video compression with the Motion JPEG 2000 extension. JPEG 2000 is a compression standard based on a discrete wavelet transform (DWT). It is possible to store different parts of the same picture using different quality.
J2k technology code#
JPEG 2000 code streams are regions of interest that offer several mechanisms to support spatial random access or region of interest access at varying degrees of granularity. The registered MIME types are defined in RFC 3745. jpx for the extended part-2 specifications, published as ISO/IEC 15444-2. jp2 for ISO/ IEC 15444-1 conforming files and. It was developed from 1997 to 2000 by a Joint Photographic Experts Group committee chaired by Touradj Ebrahimi (later the JPEG president), with the intention of superseding their original JPEG standard (created in 1992), which is based on a discrete cosine transform (DCT), with a newly designed, wavelet-based method.
JPEG 2000 ( JP2) is an image compression standard and coding system.
