Development of a Hand Pose Rally System Based on Image Processing
Suganuma, Akira,Nishi, Koki The Institute of Electronics and Information Engin 2015 IEIE Transactions on Smart Processing & Computing Vol.4 No.5
The "stamp rally" is an event that participants go the round with predetermined points for the purpose of collecting stamps. They bring the stamp card to these points. They, however, sometimes leave or lose the card. In this case, they may not reach the final destination of the stamp rally. The purpose of this research is the construction of the stamp rally system which distinguishes each participant with his or her hand instead of the stamp card. We have realized our method distinguishing a hand posture by the image processing. We have also evaluated it by 30 examinees. Furthermore, we have designed the data communication between the server and the checkpoint to implement our whole system. We have also designed and implemented the process for the registering participant, the passing checkpoint and the administration.
A Flicker-less Method Detecting the Cue Stick for a System Predicting the Path of the Billiard balls

Billiards is a game which players try to hit the balls into pocket with cue stick. Some beginner players may feel difficult to play billiards, because not predicting the path of the balls. Therefore we developed a supporting system for them. The system distinguishes among the balls, detects the cue stick and projects the path of the balls on the table by using a camera, projector and image processing. Consequently, the beginners can visually predict the path of each ball. Our system enabled players to see the movement of each ball before they shot the cue ball.

The purpose of this research is the construction of the stamp rally system distinguishing with participant"s hand shapes. We have realized by the image processing to distinguish the hand shapes and evaluated accuracy. And we have designed the data communication between the server and the checkpoint.
Effectiveness of Priority Control Method by Using Cgroups in KVM

Recently, the performance of CPUs is improving by the technology of integrating circuits. By this improving, CPUs satisfies the demand which is needed for executing software on the computer. Therefore, CPUs aren’t always used fully. To use CPU more efficiently, the virtualization technology is used in various situations such as Web service, database service, cloud computing service, and so on. In this technology, users can integrate plural VMs (Virtual Machines) on one physical computer. However, when the number of processor cores is less than the number of VMs, the scheduler can’t concurrently allocate the CPU to all VMs. In this situation, each VM is allocated the CPU by the time sharing. Therefore, when all processor cores are allocated to other executions, the executable VM waits for allocating the CPU. This situation becomes the problem when the CPU is needed for real time processing on the VM, which is ready to execute. To solve this problem, we proposed Priority Control Method, which enables us to control allocating the CPU resources for each VM. Moreover, we evaluated the effectiveness of Priority Control Method by using the priority of the process before. However, we didn’t evaluate this method in Fedora 20 that is latest version of Fedora. Moreover, Fedora 20 has cgroups (Control Groups) that is the function of managing resources. Cgroups includes the function for the control of allocating the CPU to each VM. In this paper, we describe the effectiveness of Priority Control Method with KVM (Kernel-based Virtual Machine), which is one of methods for the virtualization of the computer. Moreover, we describe the evaluation that we tried to control allocating CPU for VMs by using cgroups in KVM.
