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,

Hi Piali,

Hi Piali,

I'm curious why are you looking for Thresh functions in the signal processing domain? IPP supports 16u Thresh for image processing:

ippiThreshold_16u_C1R
ippiThreshold_16u_C3R
ippiThreshold_16u_AC4R
ippiThreshold_16u_C1IR
ippiThreshold_16u_C3IR
ippiThreshold_16u_AC4IR

regards, Igor.
