So the quality of line Vectorization is a very important mark in Vectorization performance the bases of analyzing all kinds of lines pixel distribution characteristic, Freeman restriction condition of line chains bees clear. Line Vectorization is the foundation of other graphic Vectorization. This dissertation analyses the feature of lines Freeman chain code, then brings forward a new line Vectorization method based on probability property model including selecting the next line tracking pixel and the first line mergence procedure.
