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

SunnyW — Fri, 18 Dec 2020 00:36:56 GMT

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 ?

there are no specific instructions to make this conversion.

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.

Regards,

Ruqiu
