    Language:English   Publishing type:Research paper (international conference proceedings)   Publisher:ACM  

    Yamato-e and Ukiyo-e style are Japanese traditional painting styles that have two characteristics, linearity and verticality. We propose a novel generalized projection method to produce such images using 3D computer graphics. The method enables orthographic, perspective, reverse perspective, oblique projections, and a projection with a different field of view vertically and horizontally. The key idea is to control the tilt angles of four-sided planes of a view volume indirectly and independently with the projection reference plane. It can be applied easily to user interactive CG creating tools, and it can produce pseudo multi-perspective projected images. We can see them from our implementation and the resultant images.

  • Interactive Relighting in Single Low-Dynamic Range Images Reviewed International journal

    This paper addresses the relighting of outdoor and large indoor scene illuminated by non-distant lights, which has seldom been discussed in previous work. We propose a method for users to interactively edit the illumination of a scene by moving existing lights and inserting synthetic lights into the scene that requires only a small amount of user annotation and a single low-dynamic range (LDR) image. We achieve this by adopting a top-down approach that estimates the scene reflectance by fitting a diffuse illumination model to a photograph. This approach gains stability and robustness by estimating the camera, scene geometry, and light sources in sequence and by using a confidence map, which is a per-pixel weight map. The results of our evaluation demonstrate that the proposed method can estimate a scene accurately enough for realistic relighting of images. Moreover, the experimental results of our user studies show that the synthesized images are so realistic as to be almost indistinguishable from real photographs.

    Data visualization is a powerful technique to grab its tendency in a second. Especially simultaneous visualizations of multivariate data give useful cues to know relationship between individual data. In this paper, we describe the results of our appearance test for visualization of multivariate data based on color perception within and without shadow, which is one of our visual perceptual characteristic. This result explains the importance of intensity of background color to provide right color appearance.

    For real paint, there are problems that it contains poison materials and becomes deteriorated. On the other hand, digital paint on computer is free from such problems and allows higher saturation color with recent display hardware whose gamut is very wide. However, we need to implement a lot of aspects of paint as material, because various painting techniques are based on them and painters are often inspired by them. I describe our works about it.

    Light reflected from an object to a camera is a mixture of light from specular and diffuse reflection. This has important implications for many computer vision tasks, such as image matching and understanding. Many applications, for example, digital contents production, photorealistic image synthesis, and motion analysis, may require the diffuse and specular reflection to be separated. We present an approach for separating the diffuse and specular components of object surface reflection. This approach is based on the well-known dichromatic reflection model, however it separates reflections from reflectance fields constructed for every point on a 3-D object surface. Our method can prevent having to segment image into several uniformly-colored areas. Our method can thus separate reflection from an object surface with a complicated texture. We analyzed the properties of the reflectance field constructed from original frames and showed how to separate reflection components for each 3-D point. Experiments on real scenes showed that our method was successful.

  • Weighted Separation of Surface Reflection of an Object Illuminated by Two Light Sources

    Separating the diffuse and specular components from the reflection of a 3D object surface is very important for generating highly realistic synthesized images in computer graphics applications. Most researchon this separation has only considered cases in which an object is illuminated by a single point light source. However, when an object is only illuminated by one source, acquiring the correct texture information of the visible regions on the object surface can be difficult or even impossible because of shading. To overcome this problem, we used two point light sources to illuminate the object to reduce the shaded regions. We used an iterative algorithm to estimate the intensity variation curve parameters and to compute the separation of the two components. To improve the separation quality, we used a weighting function to reduce the effect of noise contained in the highlight regions. Experiments using both synthesized and real data demonstrated that our method is effective and produces clear separation.

    A software robot in the scope of this paper is regarded as an autonomous intelligent agent situated in a virtual reality environment. As such, it is of fundamental importance to be able to create an internal representation or model of its surroundings. This model must gather the relevant to the robot scene information in a compact representation, which will subsequently be used to accommodate the robot's functional requirements. The model is also required to be incremental, in order to be able to grow and adapt to environmental information as it becomes available, and it must allow for incomplete or fuzzy knowledge to describe parts of the scene that have not been available to the robot's sensors. We propose a neural network based model along with a training technique that succeeds inmeeting these requirements.

    In hand-drawn illustrations, we often draw pictures with various thickness lines. And in some animations, lines which construct an image change their thicknesses according to the view direction. However, these features cannot be captured with traditional rendering methods. For solving these problems, we propose a view-dependent line rendering method. That is, after creating 3D data objects, a user sets each line thickness information according to the view direction. Then, it is stored to a user-defined reference table named line rendering information table. By using this method, a user can set the line rendering thickness freely in one object and can control thickness of each line according to the view direction.

    把持は物体を操作する上で最も基本となる動作であり、人間の動作を計算機上で再現する上で非常に重要である。しかし人間の手はその大きさに見合わず20を超える高い自由度を有しているため把持姿勢に関する研究は多くあるが把持した後に対象物体に対して操作を行う把持後操作まで踏み入っている研究は少ない。先行研究では初期姿勢と物体の軌跡を入力として与え内部トルクに基づき操作列を自動生成しているが、そのため初期姿勢に依存している部分が大きい。そこで本研究では物体の操作部分に着目し逆運動学に基づいた初期姿勢を必要としない物体の把持後操作の自動生成法を提案する。

    We propose a novel method of procedurally generating climbing plants using L-systems. The goal of this research is to generate geometry for 3D-modelers, where procedurally generated content is used as a base for the final design. The algorithm is fast and efficiently simulates external tropisms such as gravitropism and heliotropism, as well pseudotropisms. The structure of the generated climbing plants is discretized into strings of particles expressed using L-systems. The tips of the plant extend the branches by adding particles in its path, forming internodes. A climbing heuristic has been developed that uses the environment as leverage when the plant is climbing, and effectively covers objects on which it grows. A fast method that sprouts leaves on the surface on which the plant is growing has also been developed, along with a heuristic that simulates the decrease in length, radius and leaf size.

    Shape perception depends on a lot of factors, for example texture or shade. When rendering a surface, the question whether the viewer correctly understands the shape of the rendered object is open. The use of different rendering methods can improve or harm the perception of the shape. This paper presents a new line rendering style and evaluates its success at conveying the shape of the underlying object with respect to other styles of rendering. An experiment, comparing the perceived normal vector with the true normal vector at some points chosen on the object, shows that the style we propose performs better than a style based on principal directions of curvature for some cases.

    Animating characters in a realistic way requires the mapping from sensor data to the character. So far, this procedure known as Body Calibration is done manually, hence is really time consuming. In this paper, we propose a novel technique for automatic body calibration using sensor data acquired by a motion capture system. We determine the lengths of each bone and how far the bone is from the sensors using least squares estimation, assuming that a rough estimation of the sensor positions and a bone hierarchy are provided. This assumption implies that the bones' lengths are fixed, while actual human joints are not ideal ball joints. The resulting error leads to small gaps between bones. We propose to solve this problem by finding the optimal set of transformations that reduces the gaps while minimizing the error on the motion. To achieve fast and stable computation, we distribute the error over the joint angles using a springbased simulation of the connexion between the bones. Our experimental results show that our approach produces automatically appropriate animations faster than conventional systems.

    In order to generate controllable human animation, several methods based on the interpolation of motion capture data have been proposed. These motion parameterization methods require a data set which consists of similar motion to avoid artifacts in generated motion. However, reaching for instance, has considerable variation even for the same reaching position including the difference of the direction of hand approach and the foot to step forward. Therefore, to generate natural motion under unrestricted conditions, an automatic classifying technique is needed before interpolating motions. In our method, we adopt the Laplacian eigenmaps technique for classifying reaching motions. First, Laplacian eigenmaps method is applied to reduce the dimension of the postures sampled from the motion data, preserving local structure of the original high dimensional data. Then, k-means algorithm is used in the low dimension space to cluster the samples. At last, reaching motions are classified according to the clustering results. We applied our method to reaching data parameterized by the orientation of a tube shaped target object, and synthesized motion from classified motions successfully. Our technique enables us to apply the motion parameterization techniques to more general condition which results in more natural animation.

    Opening a door and going through it is a trivial action in ordinary life. For a virtual agent, however, actions like approaching the doorknob from an arbitrary position, pulling it, and following the door movement, all have to be taken into account in order to generate the computer graphics animation for that action. In this paper, we make use of machine learning techniques which can build models for the animation synthesis of opening a door. First we use motion capture system to acquire motion data for the typical action. The data set along with restraint conditions are fed into continuous Hidden Markov Models (HMMs) which can learn the action of opening a door. Restraint conditions are what should be considered while moving, such that the foot on the floor must not slip. To generate a new animation, the hip trajectory of a character is applied to the model, then the highest probability of state transitions in HMMs is calculated and the corresponding sequence to the transitions is generated automatically. As a result, we generate a door opening action which consists of parallel and serial motions.

    A method for evaluating image segmentation methods is proposed in this paper. The method is based on a perception model where the drawing act is used to represent visual mental percepts. Each segmented image is represented by a minimal set of features and the segmentation method is tested against a groundtruth database of sketches that represent the original images, using the Mahalanobis distance function. The covariance matrix is set using a collection of sketches drawn by different users. This evaluation method can be used to solve the problem of parameter selection in image segmentation, as well as to show the goodness or limitations of the different segmentation algorithms. Different well-known color segmentation algorithms are analyzed with the proposed method and the nature of each one is discussed. This evaluation method is also compared with heuristic functions that serve for the same purpose, showing the importance of using users' pictorial knowledge.

    In the context of video games and characters in the virtual world there has been a great demand for synthesizing realistic motions under explicit user control. In order to meet that demand, a number of methods have been proposed, which typically exploit correlations between adjacent articulation joints. These correlations can in turn be extracted from example motion capture data. In this paper, we examine the relations between the degrees of freedom of each joint individually. We then proceed to show that even when we treat each joint independently, we are able to generate animations that retain the original motion features.

    For an animated agent system which can interact with users through natural language, it is necessary to deal with the vagueness of natural language. We focused on spatial constraints in the interaction and developed a framework which can interpret thus vagueness. This paper explains the framework. At first, we analyzed and classified the spatial constraints in Japanese spatial words. In Japanese, spatial constraints are represented by nouns such as "mae (in front of)" in "tukue no mae made itte (Go to in front of the desk.)". Then, we proposed SPACE objects which represented spatial constraints in terms of both symbolic and numerical representations. Potential functions were used in these objects to express the vagueness. Finally, we implemented these objects in our animated agent system and showed examples of interactions through natural language.

    The action of grasping an object is very important for an agent with humanoid hands in the virtual world. For realistic animation, it is important for us to take into account the hands grasping motion. For this purpose, it is necessary to recognize the form of the 3-dimensional geometry, and to detect the position where a target should be grasped. In this paper, we propose a technique for detecting appropriate portions to be grasped on the surface of an object, assuming that the object is grasped by one hand and grasping is performed prioritizing stability for carrying the object. Our approach is to search for portions on the object surface which are appropriate for grasping by evaluating the similarity with the surface of a cylinder. The graspability is checked on searched surface portions. These detected portions become candidates for grasping position.

    In this paper we propose a simple method for the decomposition of point-sampled 3D objects into its basic components. Our approach is based on recent methods for fuzzy clustering and hierarchical decomposition of 3D meshes, where we use instead a k-nearest neighbor graph of the point cloud. Our approach proceeds in two steps: We first encode the geometric properties of the 3D shape into an inter-surfel distance matrix. The distance between two surfels takes into account the geodesic distance, the angular distance to measure the shape convexity and the surface variation. Then, we apply a clustering algorithm on the distance matrix to extract the different components of the input surfels. We demonstrate the efficiency of the proposed approach on a collection of point sampled 3D objects.

    In the case of generating animation of autonomous characters in virtual world, We can not prepare every action sequence. Therefore, we designed a graph style data structure, called Motiongraph. Each node has a posture of a character and links which have action segments. When a new target posture is ordered, a path is selected automatically from the graph and a sequential motion is generated. In addition, by defining ``hastiness'' values to links and by using a weighted path search algorithm, more suitable motion could be selected in situations.

    We have developed a technique for estimating the diffuse and specular reflectance parameters of a rotating 3D object from an image sequence taken by a high-definition TV camera with a fixed position and direction and with a fixed-direction light source. Many researchers have studied the computation of reflectance parameters from the separated diffuse and specular components. However, for a complicated texture, complete separation is difficult to achieve. Unlike other methods, our technique estimates diffuse and specular parameters directly from the raw RGB data by iteratively minimizing fitting errors without knowing the light source color and object color. The diffuse and specular components can then be separated using the estimated diffuse and specular reflectance parameters. Experimental results with both synthesized and real data demonstrate that this approach effectively and stably recovers the reflectance parameters.

    Contours which obtained by image processing are sometimes not continuous. So it should be connected for postprocessing. There are curve fitting methods to interpolate curves, but these are difficult to apply to arbitrary curves. We propose an algorithm which interpolates curves by calculating possibility of curve existence and joining pixels which have high possibility. Because this method calculates the possibilty of existance uniformly in the whole image, it doesn't need additional information of the image. This algorithm uses filter, so we investigated the optimum filter size for the curvature in the image. We also applied this algorithm to real image and confirmed it can interpolate Curves.

    A software robot in the scope of this paper is regarded as an autonomous intelligent agent situated in a virtual reality environment. As such, it is of fundamental importance to be able to create an internal representation or model of its surroundings. This model must gather the relevant to the robot scene information in a compact representation, which will subsequently be used to accommodate the robot's functional requirements. The model is also required to be incremental, in order to be able to grow and adapt to environmental information as it becomes available, and it must allow for incomplete or fuzzy knowledge to describe parts of the scene that have not been available to the robot's sensors. We propose a neural network based model along with a training technique that succeeds inmeeting these requirements.

    We propose a new block matching method for surface measurement of 3D objects, which is useful for precisely modeling and making high quality 3D image parts for virtual TV studio application. Multiple viewpoint images of 3D object photoed by HDTV camera within ±θ degree are used, and each image block in these images is assumed to move parallelly to central image with the same velocity. Two-step block matching algorithm is adopted to improve measurement accuracy. In our experiments, ±1 pixel accuracy was obtained in coarse matching, and final RMS error was less than 0.4 pixel with 4 times scaled images.

    Recently, the main focus of computer graphics has been the creation of photo-realistic images. In this paper, We consider hand-painted images with special emphasis on the generation of hand-painted images from natural pictures taken by a camera. We discuss the positioning of our painting algorithm in computer graphics, then explain the local image analysis. We provide further explanation of two painting algorithms based on data obtained from the image analysis. The Fourier transform and an oriented band-pass filter are used to obtain the local image analysis. One painting algorithm is generally a blurring algorithm in which the local image undergoes a blurring transform that depends on the local region. In the other painting algorithm, the image is formed from the painting of curved lines caused by the blush strokes. In this paper, we show hand-painted images using these algorithms.
