I'm looking for some methods to compute shape similarity between two curve segments.
I have two time series x1 (purple line) and x2 (red line) and I would like to find the y-offset that minimizes the difference between the two curves (the sum of the square differences), and use this difference as a similarity measure.
How can I find this offset?

After a relaxing week end, it's easier to see the obvious: it's the average distance between simultaneous points of the data sets.
