Yes, you can using tracing. Potrace is an open source bitmap-to-vector tracer library.

However, bitmap tracing is imperfect; for high-quality vector image, line tracer is generally only used to do the initial tracing, which would later be hand-tweaked. Inkscape, an open source vector image editor, provides built-in support for tracing (internally using potrace).
