Why there is no ippsThreshold function for Ipp16u?

Hi,

We are trying to use IPP for image processing.

We have image data set which has 16bits allocated but 15bits stored.We resize & interpolate using: ippiResize_16u_C1R(). We then need to apply threshold to ensure that the range of the data within 15 bits. We tried to use ippsThreshold_LTValGTVal_16s_I(). That set the values > 15 bits to 0.

There seems to be no threshold function for unsigned data. ow can we apply threshold on an unsigned 16 bits dataset?

Thanks,

PD
