text: Thus, if f {\displaystyle f} and t {\displaystyle t} are real matrices, their normalized cross-correlation equals the cosine of the angle between the unit vectors F {\displaystyle F} and T {\displaystyle T} , being thus 1 {\displaystyle 1} if and only if F {\displaystyle F} equals T {\displaystyle T} multiplied by a positive scalar.
