Abstract
Most vision researchers would agree that the medial axis
transform does not yield an ideal, or in some cases even acceptable,
skeleton. For example, single pixel irregularities can produce gross
changes in an otherwise simple skeleton. The problem of defining what
is meant by skeleton and skeletal pixel is one that has been rarely
addressed, but seems important. Here, a thinning strategy is proposed
that is based on a definition of a 'skeletal pixel'. The basic idea
is that a skeleton is a global property of a binary object, and that
the boundary should be used to locate the skeletal pixels.
