It has become much popular and easy to use real-world data such as three dimensional data as well as image data for computation and communication. In fact, real world data is rapidly increasing like range image, volumetric data, digital photo and video, etc. This kind of real world data is generally huge so that the computational and communication costs to handle such data is quite expensive. This study aimed at developing the efficient techniques for handling real-world data based on the concept of 'transdinesional processing'. The three targets are 'interpolation of 2D image', 'analysis of 3D data', and 'analysis of color'.Concerning the interpolation of 2D image, we made two achievements, namely 'painterly morphing using brush stroke model' and 'real-time view-morphing based on epipolar geometry.' The painterly morphing takes two images as input and generates a morphing sequence whose frames are all rendered in painterly style. The real-time view-morphing also takes two pictures of … More the same scene taken from the different view positions and synthesizes images from the in between viewpoints. This technique can generate images in real-time with texture mapping capability.This study also succeeded in developing 'surperspective projection of landscapes for geographical guide-map generation' and 'topological volume skeletonization of scalar field' in the sense of 3D data analysis. The former study can automatically generates a guide-map by subdividing the terrain model along ridge lines and ravine lines. The latter one provides us a new measure for analyzing the scalar field with volume skeletonization. It is applicable to design a transfer function for volume rendering.The study on color analysis achieved 'visual cryptography for natural images' and 'texture screening method for pencil drawing effects.' The visual cryptography is a kind of cryptography which can be decoded only with the human visual system. For instance, a hidden image appears if two OHP sheets with random dots are stacked together. The study developed a new technique for handling a natural image with high image quality. Less

它已经变得越来越流行，易于使用现实世界数据，例如三维数据以及用于计算和通信的图像数据。实际上，现实世界的数据正在迅速增加，例如范围图像，体积数据，数字照片和视频等。这种现实世界数据通常很大，因此处理此类数据的计算和通信成本非常昂贵。这项研究旨在根据“经跨加工”的概念来开发处理现实数据的有效技术。这三个目标是“ 2D图像的插值”，“ 3D数据的分析”和“颜色分析”。调解2D图像的插值，我们取得了两个成就，即“使用刷子笔划模型的绘画形态”和“基于Epipol epipolare sepical deepry'的实时视图模型的绘画变形”。绘画的变形将两幅图像作为输入，并生成一个变形序列，其框架的框架均以绘画风格呈现。实时视图曲线还拍摄了两张图片……更多的相同场景从不同的视图位置拍摄，并从视点之间综合图像。该技术可以通过纹理映射功能实时生成图像。这项研究还成功地开发了3D数据分析的意义上的“地理指南产生景观的相光投影”和“标量场的拓扑量骨骼化”。前研究可以通过沿着山脊线和山沟线细化地形模型来自动生成指南图。后来的一个为我们提供了一个新的措施，用于分析标量骨架的标量场。它适用于设计用于音量渲染的传输功能。颜色分析的研究实现了“自然图像的视觉加密”和“铅笔绘制效果的纹理筛选方法”。视觉加密是一种加密图，只能通过人类视觉系统进行解码。例如，如果将两个带有随机点的OHP纸堆叠在一起，则会出现一个隐藏的图像。该研究开发了一种新技术，用于处理具有高图像质量的自然图像。较少的
