摘要: 手绘草图是人类一种自然且直接的表达思想和进行交流的方式,草图创作越来越受到人们的关注。目前已有的草图创作系统主要关注的是用简单的手绘笔迹来进行建模,对单条笔迹的识别处理研究较多,但是在一定程度上限制了设计师绘制的自由性。另外,随着计算机及网络技术的发展,人们的工作方式也在悄然发生变化,协同式的工作方式提高了参与者协作交流的能力,而且还不受工作环境的限制。同时,将草图创作与协同工作相结合的应用方式并不多,因此将草绘笔迹美化与协同技术引入到基于草图的讲故事的系统中,将大大提高人们对于协同创作的兴趣,使得非专业人士均可以参与到协同创作中。 本文重点研究草图创作中草绘笔迹的美化方法以及协同创作中的冲突消解技术和用户后加入技术,并将上述技术相结合设计并开发了协同式草图创作工具,使用户可以不受地理位置局限,以协同的方式实时进行草图作品创作。 本文的主要工作如下: 1. 草绘笔迹美化技术 随意草绘的笔迹信息比较杂乱,影响了图形美观,为此本文提出了一种草绘笔迹的美化处理技术,用以分析用户的操作意图,从而对草绘笔迹做出美化处理。 2. 协同创作中的冲突解决技术 分析协同创作中的冲突原因,通过冲突检测对冲突类型进行判断,对顺序冲突和意图冲突分别给出解决方案。 3. 协同创作中用户后加入技术 分析用户后加入的同步数据不可靠问题的原因,并在分析现有用户后加入算法的基础上提出基于状态转换的用户后加入机制,该方法可有效地解决同步可靠性问题。 4. 系统的设计与实现 在以上研究的基础上,设计并实现了协同式草图创作系统,整合了草绘美化工具与讲故事工具,实现了从故事角色背景绘制、制作故事动画、到讲述故事的集成。同时,完成了协同创作中所需的服务器端、客户端以及数据库的相关功能的设计与实现。
英文摘要: Sketch is a natural and direct way of expressing ideas and communicating for human. Sketch creation has got more and more attention. At present, the existing sketch creation systems are mainly concerned with modeling by simple handwriting strokes. Most of the current research on sketch recognition is to use single strokes. However, it limits the drawing freedom of designers to a certain extent. Besides, the work way is changing gradually as the development of computer and network technology. The collaborative work way improves communication ability of participants, and frees from the restrictions of working environment. Meanwhile, there are few applications for combining sketch creation and collaborative work. So it will greatly enhance people's interest in the collaborative creation and make non-professionals participate in the collaborative creation that bringing the sketch beautification and collaboration technology into sketch-based storytelling system. In this article, we focus on sketch beautification method in sketch creation, conflict resolution and latecomer technologies in collaborative creation, which are integrated to design and develop a collaborative sketch creation tool. This tool allows users to create the same sketch works collaboratively in real-time. The main contributions of the thesis are as follows: 1. Sketch stroke beautification technology:Random sketch strokes are messier, and affect the graphics' beauty. Therefore, a sketch beautification process technology has been proposed for analyzing users' operation intention to beautify sketch strokes. 2. Research on conflict resolution technology:Analyze the conflict causes in collaborative creation, judge the conflict types through conflict detection, and give conflict solution for both order conflict and intention intentions. 3. Research on latecomer technology in collaborative creation:Analyze the causes of unreliable synchronous data in latecomer problems. Propose a latecomer mechanism according to state transition based on existing latecomer algorithms, which can solve the Synchronous reliability problem effectively. 4. Design and development of the system:Based on the above research, design and implement the Collaborative sketch creation system, and integrate the sketch beautification tool and the storytelling tool. Achieve integration for drawing the roles and backgrounds of stories, making the story animation and telling stories. Meanwhile, complete related functions in sever, client and database according to requirement of collaborative creation.
