Hi,

I've currently taken up a project on Signature Recognition and am
planning to carry out this using Dynamic Time Warping (DTW) and
Extended Regression Technique.

Could anyone please tell me how I can apply DTW to match two
signatures ( a reference and a test signature). I would be taking the
coordinates of the signature pattern which is drawn using the mouse,
normalize the coordinates and store them.

Wikipedia (http://en.wikipedia.org/wiki/Dynamic_time_warping) gave
some insights on DTW algorithm but the parameters that the function
expects are of 1 dimension, whereas the signatures would be a 2D with
x- and y-coordinate values. I am sure i'm heading the wrong way with
the logic and would be grateful if someone could help me with this
aspect.

Thank you for your time.

Best Regards,
Sachin Sudheendra.
