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.
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 ]
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]

The JPEG filename extension is JPG or JPEG. Nearly every digital camera can save images in the JPEG format, which supports eight-bit grayscale images and 24-bit color images (eight bits each for red, green, and blue). JPEG applies lossy compression to images, which can result in a significant reduction of the file size.
Preview offers basic image correction tools using Core Image processing technology implemented in macOS, and other features like shape extraction, color extraction, cropping, and rotation tools. When annotating images, Preview uses vector shapes and text until the image is rasterized to JPEG, PNG or another bitmap format.
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]
