Is there a library that can do raster to vector conversion, for the iPhone?

Question

I am trying to take an image and extract hand written text so that it can be read easily and zoomed in on. I would like to convert the text to vector paths.

I am not aware of any libraries that would make this as painless as possible. Any help is greatly appreciated. Examples are nice too :)

Simple iPhone Image Processing (on Google code) contains all the primitive tools you will need:

• Canny edge detection
• Histogram equalisation
• Skeletonisation
• Thresholding, adaptive and global )
• Gaussian blur (used as a preprocessing step for canny edge detection)
• Brightness normalisation
• Connected region extraction
• Resizing - uses interpolation
