Abstract

We introduce a simple Delaunay-triangulation based algorithm for the interactive coloring of neat line-art minimalist sketches, ie. vector sketches that may include open contours. The main objective is to minimize user intervention and make interaction as natural as with the flood-fill algorithm while extending coloring to regions with open contours. In particular, we want to save the user from worrying about parameters such as stroke weight and size. Our solution works in two steps, 1) a segmentation step in which the input sketch is automatically divided into regions based on the underlying Delaunay structure and 2) the interactive grouping of neighboring regions based on user input. More precisely, a region adjacency graph is computed from the segmentation result, and is interactively partitioned based on user input to generate the final colored sketch. Results show that our method is as natural as a bucket fill tool and powerful enough to color minimalist sketches.
交互平面色彩的极简主义整洁的草图
我们介绍了一种简单的基于delaunay三角剖分的算法,用于对整洁的线条艺术极简主义草图进行交互着色。矢量草图,可能包括开放的轮廓。主要目标是最大限度地减少用户干预,并使交互与洪水填充算法一样自然,同时将着色扩展到具有开放轮廓的区域。特别是,我们想让用户不必担心笔画的重量和大小等参数。我们的解决方案分为两个步骤:1)分割步骤,其中输入草图根据底层Delaunay结构自动划分为区域;2)基于用户输入的相邻区域的交互式分组。更精确地说,从分割结果中计算出一个区域邻接图,并根据用户输入进行交互式分割,生成最终的彩色草图。结果表明,我们的方法像桶填充工具一样自然,并且足以为极简主义草图着色。
