FAIRsharing record for: Joint Photographic Experts Group 2000

This FAIRsharing record describes: The JPEG 2000 standard is a collaboration between ITU-T and ISO/IEC and has a royalty-free objective. JPEG 2000 refers to all parts of the standard. JPEG 2000 is the Swiss Army knife of image codecs. It supports: lossy and lossless coding, up to 16384 components, bit depth up to 38 bits/sample, terapixel images, resolution and quality scalability, progressive decoding and sub-frame latency, region-of-interest accessibility, non-iterative optimal rate control, discontinuous media such as optical flow data and stereo disparity maps. JPEG 2000 is faster and higher quality than JPEG. It is used worldwide in many high-performance applications. Many CPU, GPU and FPGA implementations are available, both open source and commercial.

本FAIRsharing记录描述的内容如下：JPEG 2000标准由国际电信联盟电信标准化部门（ITU-T）与国际标准化组织/国际电工委员会（ISO/IEC）联合制定，旨在实现免版税使用。JPEG 2000涵盖该标准的全部内容范畴，堪称图像编解码器领域的万用利器。其支持的特性包括：有损与无损编码、多达16384个图像分量、采样位深最高可达38比特、太像素图像、分辨率与质量可伸缩性、渐进式解码与子帧延迟特性、感兴趣区域访问功能、非迭代式最优速率控制，以及光流数据、立体视差图等非连续类媒体的处理。JPEG 2000的编解码速度与成像质量均优于传统JPEG标准，目前已在全球众多高性能应用场景中得到广泛应用。现有诸多开源与商业级的中央处理器（CPU）、图形处理器（GPU）及现场可编程门阵列（FPGA）实现方案可供选用。
