That is, does PyrUp only insert "internal" rows and columns, does it insert rows and columns on one side, or does it insert columns on both sides?<BR /><BR />/Peter<BR /> Wed, 30 Jan 2008 14:04:35 GMT https://community.intel.com/t5/Intel-Integrated-Performance/PyrUp/m-p/857090#M7326 psnvm 2008-01-30T14:04:35Z https://community.intel.com/t5/Intel-Integrated-Performance/PyrUp/m-p/857091#M7327 <FONT face="Courier" size="2"> <P>Hi,</P> <P>The output image of ippiPyrDown_Gauss5x5_ functions is two times greater than the input image (ie widthSrc*2, heightSrc*2)</P> <P>Alexander</P></FONT> Fri, 01 Feb 2008 07:56:40 GMT https://community.intel.com/t5/Intel-Integrated-Performance/PyrUp/m-p/857091#M7327 Intel_C_Intel 2008-02-01T07:56:40Z
