https://community.intel.com/t5/Intel-Integrated-Performance/IPPI-functions-on-16-bit-frames/m-p/992627#M22500 <DIV>Hi,</DIV> <DIV></DIV> <DIV>I am writing an application which recieves 320X64sized frames from </DIV> <DIV>a frame grabber. </DIV> <DIV>Each pixel is represented in 16 bit, unsigned short. </DIV> <DIV>I didn't find the following functions in ipp libraries:</DIV> <DIV>1. Sub - There is a sub for signed 16 bit frames but not for unsigned.</DIV> <DIV>2. Thresholding - Again same problem. The function works only for signed </DIV> <DIV>short.</DIV> <DIV>3. Histogram - Same problem.</DIV> <DIV>4. Set - The set function also works for 16 bit signed short only.</DIV> <DIV></DIV> <DIV>I would rather avoid the following solutions:</DIV> <DIV>1.Convertion ofthe frame to 32 bit. This is a time consuming solution</DIV> <DIV>and I have very little time in my application.</DIV> <DIV>2. Shifting each pixel on bit to the right - Although this works I lose a </DIV> <DIV>lot of inforamtion.</DIV> <DIV></DIV> <DIV>I would appreciate your help.</DIV> Fri, 08 Apr 2005 16:34:29 GMT Yossi_C_1 2005-04-08T16:34:29Z https://community.intel.com/t5/Intel-Integrated-Performance/IPPI-functions-on-16-bit-frames/m-p/992627#M22500 <DIV>Hi,</DIV> <DIV></DIV> <DIV>I am writing an application which recieves 320X64sized frames from </DIV> <DIV>a frame grabber. </DIV> <DIV>Each pixel is represented in 16 bit, unsigned short. </DIV> <DIV>I didn't find the following functions in ipp libraries:</DIV> <DIV>1.
