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.
