i am just interested in how these things work and am after a library or paper that describes the approach that most of these take. At a guess they probably support a few basic constructs.

A large part of image processing is about reasoning about an image at a higher level of abstraction than just pixels, which is exactly what you need to do to vectorise an image.
As such, OpenCV is well worth looking at. It contains various image processing functions for blob detection and there appear to be Java OpenCV Bindings these days.
If this doesn’t suit and nor do any of the other libraries listed in What is the best java image processing library/approach?, then your easiest option might be to write a java wrapper library around autotrace or other non java vectorisation library.
