This paper presents a method which is based on edge tracking algorithm to generate line drawings from images.The algorithm consists of two parts:edge tracking and line drawing painting.For edge tracking

we propose an edge tracking algorithm based on dissimilarity measure

so that the edges that be from the edge detection operator are able to be classified and connected.In the line drawing painting process

we employ a non-uniform B-spline to interpolate for the discontinuous edge and the Gaussian function to obtain a continuous smooth lines.Then the brush is generated based on the curvature of the lines

and the line drawing of images is obtined.The experiment results of image line drawings

which is generated by our method

are demonstrated in this paper

and experiment results show that our method is able to quickly generate higher-quality line drawings.
