Transdimensional Processing of Captured Data Computation

它已经变得非常流行和容易使用真实世界的数据，例如三维数据以及用于计算和通信的图像数据。事实上，现实世界中的数据正在迅速增长，如距离图像、体数据、数字照片和视频等。这类现实世界的数据通常非常庞大，因此处理这些数据的计算和通信成本相当昂贵。这项研究的目的是开发有效的技术来处理真实世界的数据的概念为基础的“跨境加工”。针对二维图像的内插、3D数据的分析和颜色的分析，我们取得了两方面的成果，即基于笔画模型的绘画变形和基于核线几何的实时视景变形。绘制变形将两个图像作为输入，并生成其帧都以绘制样式渲染的变形序列。实时视图变形还拍摄了…的两张照片更多的是从不同的视点位置拍摄的相同的场景，并从不同的视点之间合成图像。该技术能够实时生成具有纹理映射能力的图像，并在三维数据分析意义上成功地开发了用于地理导向图生成的景观超透视投影和标量场拓扑体骨架。前者通过沿山脊线和峡谷线对地形模型进行细分，自动生成导航图。后者为体积骨架化的标量场分析提供了一种新的手段。颜色分析的研究实现了自然图像的视觉加密和铅笔画效果的纹理筛选方法。视觉密码学是一种只有人类视觉系统才能破译的密码学。例如，如果两个带有随机网点的OHP图纸堆叠在一起，则会出现隐藏图像。这项研究开发了一种处理高图像质量的自然图像的新技术。较少

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
