현재 ODS(Object Directory Service) 검색 서비스는 글로벌한 모바일 RFID 환경에 적합하지만, 지역적인 로컬 네트워크 및 정보보안이 필요한 사설 네트워크에서는 불필요한 검색시간이 요구되고 효율성이 떨어지는 서비스 시스템이다. 따라서 본 논문에서는 기존의 ODS 검색 서비스 알고리즘을 개선하여 새롭게 로컬 환경에 적합한 ODS 검색 서비스 알고리즘을 제안하고, 개선된 ODS 검색 서비스 시스템의 성능평가 결과를 제시한다..

This paper presents an automatic focal length estimation method to correct the fisheye lens distortion in a spatially adaptive manner. The proposed method estimates the focal length of the fisheye lens by generating two reference focal lengths. The distorted fisheye lens image is finally corrected using the orthographic projection model. The experimental results showed that the proposed focal length estimation method is more accurate than existing methods in terms of the loss rate.

This study derived the inter-conversion matrices, which can be used in heterogeneous image transcoding between the compressed images using different transforms, such as the $8{\times}8$ block discrete cosine transform (BDCT) and the one-level discrete wavelet transform (DWT). Basically, to obtain the one-level DWT coefficients from $8{\times}8$ BDCT, inverse BDCT should be performed followed by forward DWT, and vice versa. On the other hand, if the proposed interconversion approach is used, only one inter-conversion matrix multiplication makes the corresponding transcoding possible. Both theoretical and experimental analyses showed that the amount of computation of the proposed approach decreases over 20% when the inter-conversion matrices are used under specific conditions.

In this paper, we present a customer preference analysis system using the Bluetooth Low Energy technology. Compared to Classic Bluetooth, Bluetooth Low Energy provides considerably reduced power consumption, and cost, as well as some unique characteristics while maintaining a similar communication range. The customer preference analysis system collects nearby Bluetooth Low Energy devices using an Android mobile device via Bluetooth Low Energy. In addition, the system is capable of suggesting, and advertising products that are related to these Bluetooth Low Energy devices based on the name of their manufacturer. This feature aims to attract potential customers to purchase these products.

In this study, we implement a natural user interface/experience framework using multi-sensors: Microsoft Kinect, Leap Motion, and Myo Armband. The framework is designed for customers to use in various types of interactive applications. We integrate the functions of three sensors into an application and provide an interface for customers, who can use it to interact with a computer easily. The framework can track body information in real-time, and accurately recognize the motion of different body parts.

This paper describes a direct transmission method of multimedia data stream between a multimedia data processor and a communication interface without using system memory. I propose the direct transfer method of multimedia data through the single data path, without additional data path between a multimedia data processor and a communication interface in multimedia platforms. The hardware architecture and functions for the direct transfer method is defined. Procedure to transfer multimedia data to and from the multimedia data processor is described by means of control flow chart. Comparing the proposed method with general methods, I show that the proposed method can decrease number of bus accesses and bus cycles.
