Function Request - about ippiRemap
The ippiRemap function can use 3 types of interpolation method, which is not good enough for some applications.
I am wondering if the development team of IPP can consider to enhance this function by deploying more interpolation megthods, for example, the lanczos interpolation, Gaussian based interpolation. It is quite important for antialiasing.

By the way, I spent quite a lot of time on optimizing my own remapping function, because I did not noticed that there was ippiRemap in IPPI.
I used image blocking, parallizing with OpenMP to optimize performance of remapping function. Is there any more possible way to make improvement? I found that it is quite difficult to apply SIMD on many kinds of interpolation schemes.
