How to convet 10bit Image to 16it or 8it in IPP？

[SunnyW]

Are there api to convert 10bit Image like YCbCr42210bitTo16bit /CbCr42210bitTo8bit/CbYCr42210bitTo16bit/CbYCr42210bitTo8bit ?

There is no such API supported by IPP. Please check https://software.intel.com/content/www/us/en/develop/documentation/ipp-dev-reference/top.html

Is there any SSE/AVX  instruction to  do these conversion in high performance ?

Dear IPP user,

We have scale 12 bits image into 16 bits with 4-bit zero and 16bits pack to 12bits in IPP, while hasn't the API to convert 10bit Image to 16it or 8it currently, . But you can raise the feature request through Intel online service center https://supporttickets.intel.com/servicecenter?lang=en-US

For the SSE/AVX intrinsic, there isn't only one instruction to convert 10bit Image to 16it or 8it  directly, you need to use several instructions to meet your goal.

Here is the guide for the Intel Intrinsics:

there are no specific instructions to make this conversion.
