A Improved Generation Method of Pencil Sketching
一种改进的铅笔画的生成方法

In this paper we propose an improved method for automatically generating pencil sketching from real 2D color images. First, we apply neon processing, then negative and gradation to an image to generate contour effects in pencil sketching. Second, to obtain better effects of light and texture of pencil sketching, we use line integral convolution(LIC) algorithm, and segment the image into significant areas for LIC using an effective segmentation algorithm. Compared to the traditional method, the experiments show that our method generates images with different style fast and effectively.
