In the field of line drawing vectorization,searches about line vectorization are more important than other factors,such as vectorization of arc and ellipse.However,it is still difficult to avoid or reduce certain disdvantages,for example,the unfavorable vectorization of thin and slope lines,the easily-broken lines,and questions about end-points bad location.This paper proposes a new algorithm of line recognition based on character of pixels.It searches a group of pixels having some special characters at first,then judges if the line can grow by a statistical way called one group of three scanning lines,and finally uses a window to locate its end-points to improve its precision.Experiments show that this method enhances the anti-noise performance and decreases the quantity of fragmentation.Thus,this algorithm is valid.
