After a relaxing week end, it's easier to see the obvious: it's the average distance between simultaneous points of the data sets.
How to find the offset between two time series that minimizes their euclidean distance?

Question
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?
