CrossCorrValid_NormLevelAdvanced
Image Proximity

Primitives for computing the normalized cross correlation coefficient between two images with valid mode with large template sizes. More...

CrossCorrValid_NormLevelAdvanced

The functions compute the $\gamma_{st}(c,r)$ in General Introduction with valid mode (see Categorizations).

The functions require an additional scratch buffer and advanced scratch buffer for computations.

Note: For maximum performance oSrcRoiSize.width - oTplRoiSize + 1 MUST be an integer multiple of 4.
