LazyBrush: Flexible Painting Tool for Hand-drawn Cartoons

LazyBrush: Flexible Painting Tool for Hand-drawn Cartoons

In this paper we present LazyBrush, a novel interactive tool for painting hand-made cartoon drawings and animations. Its key advantage is simplicity and flexibility. As opposed to previous custom tailored approaches [SBv05, QWH06] LazyBrush does not rely on style specific features such as homogenous regions or pattern continuity yet still offers comparable or even less manual effort for a broad...

Color Reduction in Hand-drawn Persian Carpet Cartoons before Discretization using image segmentation and finding edgy regions

In this paper, we present a method for color reduction of Persian carpet cartoons that increases both speed and accuracy of editing. Carpet cartoons are in two categories: machine-printed and hand-drawn. Hand-drawn cartoons are divided into two groups: before and after discretization. The purpose of this study is color reduction of hand-drawn cartoons before discretization. The proposed algorit...

Algorithms for matching hand-drawn sketches

Hand-Drawn Maps for Robot Navigation

The goal of this work is to create a robot interface that allows a novice user to guide, control, and/or program a robot to perform some task. The assumption is that, although the user may be a domain expert in how the task should be done, he is not an expert in robotics. During the actual robot use, he should focus on the task to be done rather than worrying about the robot or the interaction ...

Free Hand-Drawn Sketch Segmentation

In this paper, we study the problem of how to segment a freehand sketch at the object level. By carefully considering the basic principles of human perceptual organization, a real-time solution is presented to automatically segment a user’s sketch during his/her drawing. First, a graph-based sketch segmentation algorithm is proposed to segment a cluttered sketch into multiple parts based on the...
