This paper gives a review on three illumination issues of face tracking on smart phones: dark scenes, sudden lighting change and backlit effect. First, we propose a fast and robust face tracking method utilizing continuous adaptive mean shift algorithm (CAMSHIFT) and CbCr skin locus. Initially, the skin locus obtained from training video data. After that, a modified CAMSHIFT version based on the skin locus is accordingly provided. Second, we suggest an enhancement method to increase the chance of detecting faces, an important initialization step for face tracking, under dark illumination. The proposed method works comparably with traditional CAMSHIFT or particle filter, and outperforms these methods when dealing with our public video data with the three illumination issues mentioned above.

In today's online social structure, people with electronic devices or network have been closely related to whether any of the activities, work, school, etc., is related to electronic devices, intelligent robot, and network control. The best mobility and the first rich media of these products as smart phones, smart phones rise rapidly in recent years, high speed processing performance and high free way to install software, deeply loved by many business people. However, not only for smart phone business aspects of the use, but also can engage in education of the teachers or the students are learning a great help. This study construct OCR-assisted learning software written by the JAVA made, and the installation is provided by the Android mobile phone users.

In this paper, we propose two-stage multichannel architecture for oyster product management system, called cloud stage and agent stage. There are two communication channels at each stage. In cloud stage, the embedded system in the smart scale communicates with the server through two channels, Ethernet or 3G/LTE mobile communication. In agent stage, PCs and smart phones called agents communicate with the server also through Internet and 3G/LTE mobile communication. Compared with previous system in which the amount of the oyster produced in oyster workplaces could be monitored only at the console of only one oyster main server, developed system makes it possible to monitor the amount of produced oyster at several PCs (or smart phones). In addition to the amount of oysters produced at all oyster workplaces the environment of oyster workplaces such as temperature and humidity can be monitored on agents to judge the freshness. Two-stage architecture with multiple channels makes it possible to monitor the amount of oyster product and environment of the oyster workplace at any place in real time.

This thesis is the study about application development for management obesity and personal health matters systematically based on Android smart phone system. Growing obesity problem for students organized by the lack of a device or program to manage at home has been favored as a serious problem. Currently developed smart phones has come into wide use by portable features and many applications. And to support populations of these features smart phones will be available for obesity management in your home without any equipment using. Accordingly, this paper is the study about application development for management obesity for growing students at home based on the latest smart phone platform Android.

In this paper, we conducted a study on ways to not only check disaster information on smart-phone in the event of a disaster, but also simultaneously check it on wearable devices using short-range wireless communication. Wearable devices commonly used include such devices as wireless earphones, smart bands and smart-watches. Among these devices are smart-watches that allow users to view disaster information in the event of a disaster. However, because current disaster message can only check on smart-phones, research was conducted on how to deliver disaster information received from smart-phones to smart-watches. If studies such as this paper continue, we will be able to recognize disasters more efficiently in the event of a disaster and to carry out preparations for them.

With the increase in smartphone users, attacks targeting smartphone malware, zombie smartphone, such as smart phones is increasing. Security of smart phones is more vulnerable than PC security, for a zombie smartphone and generates a serious problem than the zombie PC attack on the smartphone every day is diversification. In this paper, the comparative analysis of malicious code and smartphone DDoS attacks and DDoS attacks from the PC, When using a service by connecting to the data network, proposes a method for users to confirm the packet smartphone direct a method for detecting by using the PC malware Smart PC Phone. Propose the measures of malicious code and smartphone DDoS attacks.

As smart phones have became popular in recent years, use rate of smart phones application of mobile subscribers is now gradually increasing. Smart phones have a considerable effect on real life of users. Especially, mobile payment service using smart phones is outstanding in convenience because of its simple way to check out online. Therefore, in this paper, the database was designed for inquiring and making pre-order for take-out products based on connivence. This paper offers pre-order design to have order information standardized, menus which store owners can register and manage, and statistical data based on sales. It can be cost and time-efficient by using integrated pre-order system across all franchises. If this take-out pre-order system becomes more widely available, it will increase profit for both users and franchises due to cost and time efficiency.

Today, the development and performance of a variety of smart phones is increasing with the number of smart phone users were. Advances in mobile networks and devices are spread smart phones. Smart home was increasing the interest. But until now, the study of user-centric services that the service was not implemented. Therefore, in this paper, the situation of the user, the user-centric service model that provides a smart home provisioning system OWL modeling is proposed.

The Smart phone is the mobile phone added to mounted equipment miniaturized operating system of PC and wireless phone possible hardware, software modules. This study is examine about Smart phone supply spreading process and characteristic by age. And this study is wish to investigate about age-based features of the media usage attitude via a Smart phone as a reference questionnaire of KISA and KISDI. Smart phone is easy-to-use and excellent portability and mobility like Pocket PC. It is easy to information and data search anytime and anywhere unaffected by time and place. It is to possible a variety of information exchange with several acquaintances and easy to photos and video photography. Wish to improve the life satisfaction with widely using for smart phones at all ages.
