Jump to solution
Is there a fast MKL implementation for 2D normalized cross correlation (e.g. for matching a template patch to an image)?

yes.

the Vector Statistical Library ( VSL ) portion of the MKL supports generalized multidimensional convolution and correlation. see http://softwarecommunity.intel.com/isn/downloads/softwareproducts/pdfs/347468.pdf Chapter 2 and method

status = vsldCorrExecX(task, y, ystride, z, zstride);

in addition,

may also be helpful and informative.
