In movie and video game productions, synthesizing subtle eye and corresponding head movements of CG character is essential to make a content dramatic and impressive. However, to complete them costs a lot of time and labors because they often have to be made by manual operations of skilled artists.

Facial expression is a powerful way for us to exchange information nonverbally. They can give us insights into how people feel and think. There are a number of works related to facial expression detection in computer vision. However, most works focus on camera-based systems installed in the environment. With this method, it is difficult to track user's face if user moves constantly. Moreover, user's facial expression can be recognized at only a limited place.

"Shadow Shooter" is a VR shooter game that uses the "e-Yumi 3D" bow interface and real physical interactive content that changes a 360-degree all-around view in a room into virtual game space (Figure 1). This system was constructed by developing our previous interactive "Light Shooter" content based on "The Electric Bow Interface" [Yasumoto and Ohta 2013]. Shadow Shooter expands the virtual game space to all the walls in a room just as in Jones' "Room Alive" [Jones et al. 2014]; however, it does not require large-scale equipment such as multiple projectors. It only requires the e-Yumi 3D device that consists of a real bow's components added to Willis's interface with a mobile projector [Willis et al. 2013]. Thus, we constructed a unique device for Shadow Shooter that easily changes the 360-degree all-around view into a virtual game space.
《Shadow Shooter》是一款VR射击游戏，使用“e-Yumi 3D”弓界面和真实的物理互动内容，将房间内360度的全景变为虚拟的游戏空间(图1)。该系统是在我们之前的《the Electric bow interface》(Yasumoto and Ohta 2013)的基础上开发出的互动“Light Shooter”内容构建的。《Shadow Shooter》将虚拟游戏空间扩展到房间的所有墙壁，就像Jones的《room Alive》一样;然而，它不需要大型设备，如多个投影仪。它只需要e-Yumi 3D设备，该设备由一个真正的弓的组件添加到威利斯与移动投影仪的接口上[威利斯等人，2013]。因此，我们为《Shadow Shooter》构建了一个独特的设备，可以轻松地将360度全方位视角转变为虚拟游戏空间。

Cryotherapy is a rapidly growing minimally invasive technique for the treatment of different kinds of tumors, such as breast cancer, renal and prostate cancer. Several hollow needles are percutaneously inserted in the target area under image guidance and a gas (usually argon) is then decompressed inside the needles. Based on the Thompson-Joule principle, the temperature drops drown and a ball of ice crystals forms around the tip of each needle. Radiologists rely on the geometry of this iceball (273 K), visible on computer tomographic (CT) or magnetic resonance (MR) images, to assess the status of the ablation. However, cellular death only occurs when the temperature falls below 233 K. The complexity of the procedure therefore resides in planning the optimal number, position and orientation of the needles required to treat the tumor, while avoiding any damage to the surrounding healthy tissues.

It is a common philosophical question as to whether your blue is the same as my blue. The two-tone striped dress shown in Figure 1, which attracted a lot of attention on the Internet, gave us a clear answer: "No." Some people see the dress as blue and black, whereas others insist it's white and gold. So your blue can be my white. Why is it that people looking at the same picture perceive totally different color combinations?

Although the mobile industry has recently begun trending towards high quality graphics content, it is still difficult to satisfy this trend due to performance, power and thermal issue of GPU/CPU in mobile application processor.

In the process of editorial design, a harmonious match between a picture and a solid color is often essential to achieve a high quality of a graphical art work. Color as such is a compelling cue to elicit emotional responses and thus can enhance the emotional quality of an image. Tools and methods have been developed to automatize the color selection process, and a noticeable progress has been achieved to extract perceptually dominant colors of an image. However, little attention has been paid to the emotional characteristics of selected colors, and it has been highly relying on the color designers' manual judgments. In this study, we propose a computational method that creates a color that enhances both aesthetic and affective quality of an image, and call it a theme color.

In clinical practice, when a subject is imaged (i.e. CT scan or MRI) the result is a 3D image of volumetric data. In order to study the organ, bone, or other object of interest, this data needs to be segmented to obtain a 3D model that can be used in any number of down stream applications. When used for treatment planning these segmentations need to not only be accurate but also produced quickly to avoid health risks. Automatic segmentation methods are becoming more reliable but many experts in the scientific community still rely on time consuming manual segmentation.

Modeling 3D trees is a major theme in the field of computer graphics [Steven et al. 2012]. However, there has been little research on generating illustrations of trees [Yu-Sheng et al. 2012]. One of the ways to generate them is to render their 3D models. However, it is difficult to obtain the characteristic flat representation of illustrations because of the concentration of foliage in the central part of the tree. We present a system to generate a wide variety of tree illustrations by controlling the density of branches, the shape of canopy, and the overlap of flowers and leaves (Fig. 1).
