Abstract
This paper describes an improvement of pencil stroke map which is proposed as a pencil line drawing method. Pencil stroke map detects gradient of image and products pencil line drawing by convolution line segment with respect to each angle of gradient. However, this method has the problem that if length of line segment for convolution is unsuitable for size of graphic, resulting image loses the shape of them or degrades its quality as pencil line drawing. On this account, proposed method classifies graphics by size and change the length of line segment depending on classification result, resulting image can be obtained with improved this problem. In experiment, this paper shows effectiveness of proposed method by comparison of resulting image between proposed method and pencil stroke map.
