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.
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.
[3] [4] [5] Kakadu library is heavily optimized and is a fully compliant implementation. Also, it has built-in multi-threading. [2] In a 2007 study Kakadu outperformed the JasPer library in terms of speed. [6] A more thorough comparison done in 2005, however, has shown that Kakadu does not achieve the best performance, in terms of compression ...
Typically, compressions using lossless operation mode can achieve around 2:1 compression ratio for color images. [5] This mode is quite popular in the medical imaging field, and defined as an option in DNG standard, but otherwise it is not very widely used because of complexity of doing arithmetics on 10, 12, or 14bpp values on typical embedded 32-bit processor and a little resulting gain in ...
Part 3 (ISO/IEC 21122-3) specifies transport and container formats for JPEG XS codestreams. It defines the carriage of important metadata, like color spaces, mastering display metadata (MDM), and EXIF, to facilitate transport, editing, and presentation.
Caitlin Clark had a strong response to Megyn Kelly's criticism about her recent comments regarding white privilege in the WNBA. A day later, Clark spoke at the “A Year in Time” event in New ...
The College Football Playoff selection committee enters its final two weeks of deliberation with a host of consequential decisions thrust on the 13 members.
Motion JPEG 2000 (MJ2 or MJP2) is a file format for motion sequences of JPEG 2000 images and associated audio, based on the MP4 and QuickTime format. Filename extensions for Motion JPEG 2000 video files are .mj2 and .mjp2, as defined in RFC 3745.
