Measuring local similarity

Consider the task of measuring similarity between two different signals $a(t)$ and $b(t)$. One can define similarity as a global correlation coefficient and then, perhaps, measure it in sliding windows across the signal. The local construction from the previous section suggests approaching this problem in a more elegant way.
