Intel IPP convolution deprecated — is there a different IPP 2D convolution method?

Question

I'm experimenting with Intel Integrated Performance Primitives (IPP) , and I'm curious about the "right way" to do 2D convolution in IPP.

According to the Intel IPP documentation, ippiConvFull ( documentation ) and ippiConvValid ( documentation ) are deprecated. However I don't see any other 2D convolution routines in IPP.

I did some searching, and I didn't find any alternative IPP functions for 2D image convolution.

• Is there a replacement for ippiConvFull and ippiConvValid in IPP?
• Or, is Intel just removing convolution from IPP?

Answer 1

You can use ippiFilter instead. It is not marked as deprecated and operates in 2D.

Answer 2

It seems they are deprecated (At least not in the latest IPP v 8.1):

Intel IPP Convolution .

Yet, there's a new function ippiConv which does both using the flag algType .

It should work for you.
