Research on a support system for generating comfortable hand-drawn like curves

在本研究项目中，我们研究了一个用于生成舒适的手绘类曲线的初学者支持系统及其相关的研究领域。结果提纲如下：初学者要画出高质量的图画并非易事。如果电脑把初学者不熟练的图片修改成高质量的图片，我们在很多情况下都很高兴。为此，我们考虑在绘画中使用专家绘制的图片的特征。我们提出了一个支持系统，它利用绘图专家绘制的曲线的特点，将初学者绘制的不熟练的曲线修改为高质量的曲线。改进后的曲线既保留了初学者曲线的印象，又保留了专家曲线的特征。此外，我们还提出了一种既能处理一般形式(骨架线)又能处理轮廓线强度的方法。使用该方法的原型系统，我们测试了是否制作出高质量的手绘类似轮廓的线条(具有强度)。作为上述主要研究的相关工作，我们主要做了以下五个方面的工作：1.开发了一个支持新手插图的便捷系统；2.基于曲率分析和FFT的人脸关键线曲线的研究；3.基于VR系统的汽车外形印象评价；4.日本刀剑曲线的分析；5.考虑驾驶员价值感的汽车导航信息设计优化

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
