项目摘要

In this research project, we have investigated a beginner's support system for generating a comfortable hand-drawn like curve, and its related research areas. The outline of the results is as follows.It is not easy for beginners to draw high quality pictures. If computers modify beginner's unskillful pictures into high quality ones, we are happy in many cases. To this end, we consider to use the features of pictures drawn by experts in drawing. We have proposed a support system that modifies an unskillful curve drawn by a beginner in drawing into a high quality one using the features of curves drawn by an expert in drawing. The modified curve preserved impression of the beginner's curve while having features of the expert's curve. Moreover, we have proposed a method to treat not only the general form (skeleton line) but also the strength of the silhouette line. Using a prototype system of the method, we experimented whether high quality hand-drawn-like silhouette lines (with strengths) were made. As a result, we confirmed that our method was effective in making those silhouette lines.As the related works of the above main research, we have done following five themes.1.Development of a handy system to support novices' illustrations2.Study on key-line curves of faces using curvature analysis and FFT3.Evaluation of impression for automobile configuration using VR system4.Analysis of the curves of Japanese swords5.Optimization of information design in car navigation considering drivers' sense of value

在本研究计画中，我们探讨了一个初学者的支援系统，以产生一个舒适的手绘类曲线，及其相关的研究领域。结果概述如下。初学者要画出高质量的图片并不容易。如果电脑能把初学者不熟练的图片修改成高质量的图片，在很多情况下我们是很高兴的。为此，我们考虑在绘图中使用专家绘制的图片的特征。我们已经提出了一个支持系统，修改一个不熟练的曲线绘制的初学者在绘图成一个高品质的曲线使用的特点绘制的专家在绘图。修正后的曲线既保留了初学者曲线的印象，又具有专家曲线的特征。此外，我们提出了一种方法，不仅处理一般形式（骨架线），但也强度的轮廓线。使用该方法的原型系统，我们实验是否高质量的手绘样轮廓线（强度）。作为上述主要研究的相关工作，本课题主要完成了以下五个方面的工作：1.开发一个方便的系统来支持初学者的学习; 2.关键技术的研究; 3.利用VR系统对汽车外形的印象评价4.日本刀的曲线分析5.考虑驾驶员价值观汽车导航信息设计
