Senthil,

it seems to be the same issue as you already reported in thread http://software.intel.com/en-us/forums/showthread.php?t=67282

The problem is that implementation of DICOM format parser we provide in UIC sample is quite simple and do not care about all possible cases (DICOM is a bit complicated format). It's main purpose was to demonstrate the IPP JPEG codec might be used in medical imaging and provide good performance.

We will fix this particular issue but can't commit to complete support of DICOM format. Usually, our customers have their own DICOM parsing environment and just substitute performance critical parts by UIC codecs.

What is your purpose of testing these DICOM files?

Regards,
Vladimir

Hello Vladimir,

Our most of the testcase images are in DICOM format.
mostly all the images are passing, and few images are failing. if you fix this issue, its useful for us.

Thanks and Regards
Senthil.
