Hierarchical JPEG Encoder/Decoder

问题

Does anyone knows of any implementation of the hierarchical JPEG mode (ITU T.81) ? I am not talking about progressive mode (or sequential), I really mean the hierarchical mode.

After some googling, I finally found out:

• https://github.com/thorfdbg/libjpeg

Which was referenced from:

• http://calendar.perfplanet.com/2012/progressive-jpegs-a-new-best-practice/

This seems by far the more advanced option. Some other results showed:

• http://flying_oe.tripod.com/academic/SoC/cs3242/index.html

And some explanations from:
