The paper presents a framework for automatically natural image sketching, motivated by imitating the human line drawing process. The algorithm consists of two steps: sketch extraction and sketch rendering, using the recent computer vision and graphics techniques. In the first step, we design a bottom-up filter bank (low-level features) to propose sketch strength, position and orientation, and then trace and complete sketch following Gestalt laws (middle-level cues). In the second step, each… CONTINUE READING
