[Insight-users] Performance regression in ITK + gdcm 2.0 reading DICOM JPEG files

[Roger Bramon Feixas]

Hi,

Have you had time to think about the causes of the performance regression
problem? I can work on it, but I would like to have, if you have it, some
information which helps me to know where I need to focus the effort.

Thanks,

Roger
