Which is the best way to filter unsigned images?

[Intel_C_Intel]

I'm working with monochrome images (12 or 14) bits.
Which is the best approach if I need to use IPP functions with signed 16 bits arguments?
For example, if I want to use ippiFilterSharpen_16s_C1R with 12 bits images, can I simply threshold the result image between 0 and 4096 with ippiThreshold_LTValGTVal_16s_C1IR or is there something better to do to convert back the result image to the original format?
Thank you very much

Hi,

You are right, you should use IPP functions in a manner you described.
