高分辨率JPEG 2000（HTJ 2K）是JPEG 2000系列标准的第15部分，并作为ITU-T T.814发布|ISO/IEC 15444-15。HTJ 2K为采用JPEG 2000技术的图像压缩流水线带来了编码吞吐量的显著提高。提出了一种HTJ 2K的开源C++实现方案。实现的原则是“易于理解HTJ 2K编解码器内部所做的事情”和“易于使用”。与现有的开源实现不同，我们的解码器完全符合新版JPEG 2000 Part 4中定义的一致性测试。实验结果表明，该编解码器的编码/解码速度方面表现良好。
The High Throughput JPEG 2000 (HTJ2K) is Part 15 of the JPEG 2000 family of standards, and it is published as ITU-T T.814 | ISO/IEC 15444-15. HTJ2K brings significant improvement of coding throughput to image compression pipelines with JPEG 2000 technology. In this paper, an open-source C++ implementation of HTJ2K is proposed. The principles of the implementation are "easy to understand what is done inside HTJ2K codec" and "easy to use." Unlike the existing open-source implementation, our decoder is fully compliant with the conformance testing defined in the new edition of JPEG 2000 Part 4. The experimental results demonstrate the proposed codec performs well in terms of encoding/decoding speed.
