Some years ago I looked for such a library, but I never really found
one. OpenCV has some stuff, but I doubt that it is the most efficient
solution you can find. OpenCV was essentially started by Intel to be
able to sell more copies of the "Intel Performance Primitives (IPP)"
library, so OpenCV uses this proprietary library in many places (I
assume in convolution as well).
