ippiResize* performance problem (STATIC library to build customized DLL)

For any size of images, IPP 7.0.3 is 10% slower than IPP 6.1.x to resize by ippiResize*(IPPI_INTER_SUPER) and ippiResize*(IPPI_INTER_CUBIC) functions.

Hello,

Are you using ippiResize_ functions or ippiResizeSqrPixel_ function?

ippiResize function is depreciated, and need to be replaced by ippiResizeSqrPixel_ function.

thanks,
Chao

Hi Bell,

I checked with the function owner, no change on source code of this function. No quit sure if the compiler update will bring a little performance impact for this particular function. Since this is depreciated, no update/optimization will happen on this function, any particular reason that you want to use this function other than move the ippiResizeSqrPixel_ function.

Thanks,
Chao
