    Article Snippet: Briefly, in the generic convolution integral (using as the convolution operator) for two different functions f ( r ) and g ( r ), we replace g ( r ) with g (− r ) which changes the second integrand to g ( r + u ) and the convolution into a correlation: Next, we substitute ρ for both g and f (same function, thus ‘auto’ in correlation).
