What sort of acceleration does openCV use ? How can it process so fast?

问题

I've been using openCV quite a bit lately and I'm amazed at how fast it can process arrays. Is it using a special type of optimization or relying on special features of the CPU ? I'm on an Intel CPU btw.

回答1:

OpenCV uses the Intel Integrated Performance Primitives under the hood. this library relies on aggressive optimization as well as careful use of special CPU features (SSE, SSE2, ...)
