In this PlayStation 3 and Xbox 360 game-opening cinematic for Konami Digital Entertainment, the goal was to realistically capture the dramatic moment. The production team worked especially hard on expressing the most tense parts of the game. They created a photo-real image and used stop motion and applied color with painted texture for each climactic moment. The combination of this photo-real approach and picturesque features produced a unique graphical theme.

Global tone mapping operators (TMOs) are better in preserving the naturalness and relative illumination of the HDR scene compared to the local TMOs. However, they cannot preserve the details like the local TMOs. We propose a human visual system (HVS) based histogram method for global tone mapping, which can better preserve the details than the existing global TMOs. Our method can be incorporated to all histogram based global methods. We compare our results with traditional histogram adjustment by Ward et al. [Larson97] and photographic TMO [Reinhard2002], and in most of the cases our method is better in preserving the details of the input HDR images.

Point data are basic media for shape information acquisition and representation. A new approach is presented for global parameterization of unorganized point data and application to the meshing of point models with noises. While most of recent researches focus on quadrangulation of mesh models, it is extended to point models in this work, so as to loosely reconstruct the shape model by quadrilateral meshing of curvature isolines. The new approach is guided by principal directions, so as to preserve intrinsic geometric properties. A robust method is applied to estimate curvatures in presence of noise and outliers based on fitting surface normals. The parameterization of [Ray et al. 2006] is then adapted to point data by local Delaunay triangulation. Isolines are extracted by discarding and merging the redundant segments in each local triangle. This method is totally automatic, and a high-quality quadrilateral dominated mesh can be generated, as shown in Figure 1.

This work addresses the challenge of synchronizing multiple sources of visible and audible information from a variety of devices, while capturing human motion in realtime. Video and audio data will be used to augment and enrich a motion capture database that will be released to the research community. While other such augmented motion capture databases exist [Black and Sigal 2006], the goal of this work is to build on these previous works. Critical areas of improvement are in the synchronization between cameras and synchronization between devices. Adding an array of audio recording devices to the setup will greatly expand the research potential of the database, and the positioning of the cameras will be varied to give greater flexibility. The augmented database will facilitate the testing and validation of human pose estimation and motion tracking techniques, among other applications. This sketch briefly describes some of the interesting challenges faced in setting up the pipeline for capturing the synchronized data and the novel approaches proposed to solve them.

In pre-war Japan, kimonos were encoded with clues indicating gender, caste, age, class, and social ranking. Geographical location defined the colors, as certain plants that produced particular colors only grow in certain regions. Silk techniques are also regional, and the difference between fine and rough silk indicated relative wealth.

Knowing the conditions on an emergency environment is useful for rescuers to take critical decisions in saving a life. A specific case is an ice-covered lake where accidents of people falling through ice occur. It is desirable that trained rescuers reach the victim by going over the ice within three minutes from the moment that they arrive to the scene [1999]. However, it is difficult to achieve this efficiency since they start making a plan after arriving and evaluating the situation. Therefore, we propose an ice rescue support system for estimating dangerous zones. Rescuers are provided with the application to visualize the ice condition by computer graphics (CG) and plan candidate routes before arriving. A model [1990] has obtained the average of ice thickness for the whole lake. We consider a detailed thickness resolution by a physics based approach because it varies between small distances. Lake morphology is needed to predict ice variations although most lakes have not been surveyed. Our method estimates the morphology based on a model [2000] from hydrology, and constructs geometrical representations that contribute to predict the ice condition over time.

Most of the real world scenes have a very high dynamic range. However the common capture and display devices can handle only a limited dynamic range. General approach to solve this problem is to use multi-exposure images and composite them in the irradiance domain to get a High Dynamic Range (HDR) image [Reinhard et al. 2005]. The generated image will be able to represent the real world scene faithfully. However, it needs to be tone-mapped to a Low Dynamic Range (LDR) image for visualization in common displays and printers. Generation of the high-quality LDR image of the scene directly from multi-exposure images even in the absence of any knowledge of camera response function and the exposure settings of the camera is of interest to graphics community. We propose a gradient domain compositing technique to solve the above problem and call it Poisson Compositing. We compare the proposed methodology with similar existing techniques and show that the proposed method is very fast and accurate.
大多数真实世界的场景都有非常高的动态范围。然而，普通的捕获和显示设备只能处理有限的动态范围。解决这一问题的一般方法是使用多曝光图像，并在辐照域进行合成，得到高动态范围(High Dynamic Range, HDR)图像[Reinhard et al. 2005]。生成的图像将能够忠实地代表现实世界的场景。但是，为了在普通显示器和打印机中显示，它需要色调映射到低动态范围(LDR)图像。在不了解相机响应函数和相机曝光设置的情况下，直接从多曝光图像中生成高质量的场景LDR图像是图形界感兴趣的问题。为了解决上述问题，我们提出了一种梯度域合成技术，称之为泊松合成。我们将所提出的方法与现有的类似技术进行了比较，结果表明，所提出的方法是非常快速和准确的。

Pose Space Deformation (PSD) [Lewis et al. 2000] is a shape interpolation technique for animation. This method uses radial basis functions (RBFs) to perform per-vertex, multidimensional scattered-data interpolation. This formulation effectively interpolates a driven shape according to a set of targets, each at a particular driver value. In the case of correcting a pinched elbow, the skinned geometry is the driven, the targets are the sculpted adjustments, and the driver is the elbow joint. This paper presents some practical experience with PSD acquired while creating the film BOLT.

The goal of this project is to use shape-memory-alloy actuators to realize a wriggling creature. Normally, a shape-memory-alloy actuator generates a well-defined action (robot appendages grip something or walk). But in this project, precisely controlled actuators express wriggling and creature expression. It demonstrates that an assembly of actuators can be applied to shape display of 3D objects by increasing the number of actuators and the resolution.
