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] OpenJPEG is a fork of libj2k, a JPEG-2000 codec library written by David Janssens during his master thesis at University of Louvain (UCLouvain) in 2001.
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] The library is faster than JasPer or OpenJPEG libraries and has approximately the same decoding speed as Kakadu. [4]
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.

[2] [3] Its first version, ImageJ 1.x, is developed in the public domain, while ImageJ2 and the related projects SciJava, ImgLib2, and SCIFIO are licensed with a permissive BSD-2 license. [4] ImageJ was designed with an open architecture that provides extensibility via Java plugins and recordable macros. [ 5 ]
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 quality. [7]
As such, it is a block-based transformation scheme with eight bits of color depth and a luminance–chrominance model with chroma subsampling by a ratio of 1:2 (YCbCr 4:2:0). [25] Without further content, the mandatory RIFF container has an overhead of only twenty bytes, though it can also hold additional metadata. [ 4 ]
Live2D is an animation technique used to animate static images—usually anime-style characters—that involves separating an image into parts and animating each part accordingly, without the need of frame-by-frame animation or a 3D model.
