JPEG2000是新一代静态图像压缩格式，有望取代现行JPEG，应用于网络、媒体等。Motion - JPEG2000项目支持运动图像，将用于数字电影业务。目前JPEG2000资源少，经典范例是Kakadu程序，本文将基于该程序在JPEG2000文件上的应用作简要说明。

　　JPEG2000是新一代的静态图像压缩格式，它可能将取代现行的JPEG最终应用于网络和媒体，甚至一些对图像质量和（或）码率要求很高的场合。正在进行中的Motion-JPEG2000项目将支持运动图像，它将以其高端特性应用于数字电影业务，但是从目前看Motion-JPEG2000是一种基于JPEG2000帧内压缩而无帧间编码的格式，所以对JPEG2000的了解就非常重要。JPEG2000目前的资源相对较少，经典的范例是David Taubman的程序Kakadu。这里，我将基于其程序在一个简单的JPEG2000文件上的应用作简要说明。本文仅用于学习参考，涉及源码和技术版权属于原作者David Taubman。

在之前的时候，毕业设计中实现了显微图像JPEG和JPEG2000编解码系统，分别实现了JPEG压缩编码和JPEG解码的功能以及JPEG2000编解码，JPEG编码压缩的核心是DCT变换和量化；JPEG2000编码的核心是小波变换和变换量化。下面展示了JPEG&JPEG2000编解码系统的界面和效果图。

　　解码过程的最关键部分由与kdu_decoder类一一对应的实体类kd_decoder对象完成。每个kd_decoder对应一个分量的一个子带（subband）。在kd_decoder构造的时候，主要工作是从字带对象band中获取关于码块的信息：　　nominal_block_size——码块大小　　first_block_size——实际（在子带中的）首码块大小　　block_indices—

在有损压缩下，JPEG2000一个比较明显的优点就是没有JPEG压缩中的马赛克失真效果。JPEG2000的失真主要是模糊失真。模糊失真产生的主要原因是在编码过程中高频量一定程度的衰减。传统的JPEG压缩也存在模糊失真的问题。

Changes from version 2.2.2 to version 2.2.3 ------------------------------------------- * Extremely minor changes to avoid mixed use of formatted and unformatted calls to "ostream" objects. These appear to excite a bug in GCC version 3.0. The only file affected is "params.cpp" in "coresys/parameters". Changes from version 2.2.1 to version 2.2.2 ------------------------------------------- Note: none of these have any impact whatsoever on executable code or DLL's. * Renamed the "core" directory as "coresys". A trivial change and my appologies for those whom this might adversely affect. However, the use of the name "core" was causing some people difficulties, since it is identical to the name of a Unix core dump file. * Made the Linux MMX-optimized functions "extern C" instead of "extern", so as to avoid problems caused by different name mangling conventions between various versions of gcc. * Eliminated multi-line comments from assembler files so as to avoid problems created by earlier versions of the gnu assembler. Changes from version 2.2 to version 2.2.1 ----------------------------------------- * Replaced the C++ I/O routines used for image and compressed data transfers with ANSI C I/O functions. This was motivated by the fact that the new-style ANSI C++ I/O package is unbelievably slow, at least as implemented in Microsoft's Visual C++ compiler. The change has no impact whatsoever on the Kakadu core system; it affects only the implementation of a few application level objects -- the core system abstracts all such I/O considerations through interface classes which are implemented by applications. Everything now runs a little faster than it did in version 2.1 and quite a bit faster than it did in the first release of version 2.2. * Made provision for compiling under versions of GCC prior to version 3.0. To use this, you should define GCC_VERSION_LESS_THAN_3. Changes from version 2.1 to version 2.2 --------------------------------------- * Extensive support for ROI (Region of Interest) specification at encode time (see "kakadu.pdf" for more on this). * Migrated from the old-style C++ iostream package to the new standard iostream package -- minimal use of "using namespace std" and never used in common header files, so this should enhance namespace protection and portability. * Added AT&T style versions of the small amount of Pentium assembly code to enable compilation of a high speed version under GCC as well as MSVC. * Some minor bug fixes. Changes from version 2.0.2 to version 2.1 ----------------------------------------- * Extensive support for working with the JP2 file format. The "kdu_show" application demonstrates the capabilities required of a conformant JP2 reader: palette mapping; interpolation of components to a common resolution; application of registration offsets in the CRG marker segment; and colour conversion to an appropriate rendering space (sRGB here). The "kdu_region_decompressor" object provides extensive support for general purpose interactive rendering applications, performing all of the above tasks in a platform independent manner. * It is now possible to directly control rate-distortion slope thresholds used in the construction of quality layers. This capability may also be used to significantly increase compression speed, if a suitable threshold is known, since the encoder then incrementally predicts the point at which there is no point in coding further coding passes. * A number of improvements to the "kdu_show" application, including the ability to arbitrarily zoom into images. * A number of minor bug fixes, including one important bug reported by Aaron Deever of Kodak, and a bug which occasionally manifested itself in the incremental rate prediction heuristic (reported by Jim Andrew of CISRA). * Improved documentation. Changes from version 2.0.1 to version 2.02 ------------------------------------------ * A PDF document (documentation.pdf) has been prepared to guide the new user into some of the more important aspects of the Kakadu system. The first draft is included here. * A very simple compression example and a very simple decompression example have been added to assist developers in familiarizing themselves with the Kakadu system -- the existing demo apps provide perhaps too much functionality to be quickly understood. * A full BIBO (Bounded Input Bounded Output) numerical analysis of the DWT and other processing steps is used to establish the best utilization of limited precision sample data representations. The new version should not be able to fall prey to numerical overflow or underflow difficulties under any circumstances (this could just have been possible with the last version). It also provides slightly higher accuracy. * The automatic heuristic for generating quality layer rate targets has been substantially improved. * A number of minor bugs/limitations were corrected, although these had not manifested themselves in any real examples. Changes from version 2.0 to version 2.01 ---------------------------------------- * One line change in each of "kdu_expand.cpp" and "kdu_compress.cpp" to correct a minor rare bug in these demo applications. * Minor changes in "kdu_show.cpp" to correct a rare bug and improve the user interface in regard to image rotation. * Four lines added to each of "encoder.cpp" and "decoder.cpp" to fix a minor memory leak.
