JPEG 2000 (JP2) is an image compression standard and coding system. It was developed from 1997 to 2000 by a Joint Photographic Experts Group committee chaired by Touradj Ebrahimi (later the JPEG president), [1] 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.
He is also an author of EBCOT, one of the algorithms used in JPEG 2000. [2] The software library is named after Kakadu National Park. It is used by several applications, such as for example Apple Inc. QuickTime. It is also used in Google Earth and the online implementation thereof as well as Internet Archive. [3] [4] [5]
CCSDS 122.0 makes use of a three-level two-dimensional discrete wavelet transform (DWT) using a biorthogonal 9/7 tap filters, followed by a bit-plane encoder. It has some design commonalities with ICER and JPEG 2000 that use similar wavelet coding schemes. The transform (DWT) can be computed using either floating-point or integer arithmetic.
OpenJPEG is an open-source library to encode and decode JPEG 2000 images. As of version 2.1 released in April 2014, it is officially conformant with the JPEG 2000 Part-1 standard. [ 3 ] It was subsequently adopted by ImageMagick instead of JasPer in 6.8.8-2 [ 4 ] and approved as new reference software for this standard in July 2015. [ 5 ]
J2K-Codec is a commercial library to decode JPEG 2000 images. Version 2.0 was released on 12 April 2011. [1] J2K-Codec supports decoding of different resolution levels and selective tile decoding. [2] It also supports files, produced by ADV202/ADV212 hardware chips. [3]
Grok is a computer software library to encode and decode images in the JPEG 2000 format. It is designed for stability, high performance, and low memory usage. Grok is free and open-source software released under the GNU Affero General Public License (AGPL) version 3.
Each reel contains pictures as MPEG-2 or JPEG 2000 essence, depending on the adopted codec. MPEG-2 is no longer compliant with the DCI specification. JPEG 2000 is the only accepted compression format. Supported frame rates are: SMPTE (JPEG 2000) 24, 25, 30, 48, 50, and 60 fps @ 2K; 24, 25, and 30 fps @ 4K; 24 and 48 fps @ 2K stereoscopic
The raw image format Digital Negative (DNG) allows image data contained within to be compressed using JPEG XL. Starting in version 1.7.0.0 from June 2023, JPEG XL compression was included as part of the specification. [39] This created a basis for later use as part of "Expert RAW" in Samsung Galaxy smartphones and Apple's "ProRAW".
