Converting image to Point array

[Aster]

Hi there. I'm currently working on some school project which is about signature verification. This verification could be done on two ways, one is online where system captures many parameters including motion speed, pen pressure, etc., and the other is offline where we have image of signature and system does verification through comparing this image to template stored in database.
For example, JAVA software that has Panel on which we use mouse to draw signature is online verification system. This is captured as Point array.
My problem is how to "convert" signature from images to Point array, no background, just array of points along the signature line. Is it possible at all? :)

Best regards,
Maja

Think how you would do it if you had the signature on a sheet of graph paper. And if you're not familiar with it, go through the API of BufferedImage.
