Edge detection is one of issues with essential importance in the area of image process. An edge in image is a boundary or contour which a significant change occurs in image intensity. In the paper, we process edge detection algorithms which are based on Potts automata. The dynamical behavior of these automata is completely determined by Lyapunov operators for sequential and parallel update. If Potts Automata convergence to fixed points, then it can be used to image processing. From the generalized Potts automata point of view, we propose a Potts Automata technique for detecting edge. Based on the experimental results we discuss the advantage and efficiency.

본 논문은 오프라인 환경에서 연구되던 행위인식 연구들이 온라인 환경에서 통합되어 동작할 수 있도록 하기 위해 스트림데이터 처리기를 이용한 행위인식 시스템을 제안하였다. 스트림데이터 처리는 멀티 센서 환경에서의 방대한 센서 데이터를 처리하기 위한 기술로서, 행위인식 시스템의 실시간으로 발생하는 데이터를 즉각 처리하여 결과를 추론하여야 한다는 요구사항을 만족시킬 수 있다. 이를 위해 행위인식에 사용되는 필수적인 연산을 정의하여 스트림데이터 처리기에 추가할 수 있도록 행위 인식에 필요한 각종 연산자를 설계하였다.

During transients or major upsets, operators of a nuclear power plant are faced with a significant amount of information which oftentimes exceeds their capability of processing information in such a time-critical situation. To help resolve this problem of information overload, considerable work is underway worldwide to improve its man-machine interface systems (MMISs). The I&C research team of KAERI is developing a DYNamic Alarm processing System, called DYNAS, to suppress unnecessary or nuisance alarms, and at the same time, emphasize vital information. This paper describes our basic strategy to process alarms in DYNAS.

In recent years, business environments have become more complex; therefore, enterprises must be capable of responding flexibly and agilely. For these purposes, effective enterprise systems service monitoring and early decision making based on the same, emerge as core competency of the enterprise. In addition, enterprise system techniques that filter meaningful data are needed to event processing. However, the existing study related with this is nothing but discovering of service faults by monitoring depending upon API of BPEL engine or middleware, or is nothing but processing of simple events based on low-level events. Accordingly, there would be limitations to provide useful business information. In this study, we present an extended event processing model that enables delivery of more valuable and useful business information through situation detection. Primarily, the event processing architecture in an enterprise system is proposed as a definite approach, and then define an event meta-model suitable for the proposed architecture. Based on the defined model, we propose the syntax and semantics of the elements that make up the event processing language include various and progressive event operators, the rules, complex event pattern, etc. In addition, an event context mechanism is proposed to analyze more delicate events. Finally, the effectiveness and applicability of proposed approach is presented through a case study.

A new interpolation function, named modified raised-cosine interpolation, is proposed. This function is derived from the linear combination of weighted triangular and raised-cosine functions to reduce the effect of side lobes which incur the interpolation error. Interpolation error reduces significantly for higher-order convolutional interpolation functions of linear operators, but at the expense of resolution error due to the attenuation of main lobe. However, the proposed interpolation function enables us to reduce the side lobes as well as to preserve the main lobe. To prove practicality, this function is applied in image reconstruction and enlargement.

Round-cornering machines are mainly used for cornering of stiffners for ship buildings. In the present time they have been operated manually by operators. so they are need to be operated automatically without regard to any shapes of stiffners. We developed the automatic round cornering system which consists of CCd Camera, PC and laser diode to detect automatically the edge of stiffners to be processed

For producing iron or steel products with good quality, the concentration of the material components should be analyzed quickly with high relability using XRF(Fluorescent X-Ray Spectrometer). Since the analysis results are much dependent upon the surface con- dition, the samples have to be prepared to have good test condition. This study presents an image processing system for inspecting the surface condition of the iron test sample. In order to use thd computer vision system, we need to develop a lighting device and image processing algorithm. For the adequate lighting device of inspection system, the indirect lighting device is contrived to cut the external light and provide uniform, stable and cold light. The image processing algorithm is aimed to reduce inspection time and to get similar analyzing results to those of the experienced operators. At first, the image processing algorithm checks whether the surface of the iron sample is ground well or not. Then, the defects; hole or dig are conted and surface condition is evaluated. In addition, the algorithm gives the reliability of the analyzing results in order to help operator's decision.

선박교통관제사는 관제구역 내 통항선박의 동정을 관찰하고 필요한 정보를 제공하고 있다. 이를 위해 관제구역 내 선박과 교신을 하며, 교신내용은 수기로 관제일지에 기록하고 있다. 그러나 수기로 작성하는 관제일지는 상황적 한계로 내용을 상세히 기록할 수 없으며, 여러 업무로 매 순간 기록하기는 어려운 실정이다. 본 연구의 목적은 관제사 시선분석을 통해 수기로 기록하고 있는 관제일지의 업무량을 정량적으로 분석하는 것이다. 이를 위해 부산항 선박교통관제사를 대상으로 시선추적장치를 활용하여 당직자의 시선을 측정했다. 시선 측정결과, 해상교통정보가 집중되는 운용콘솔에 약 65% 시선이 향하고 있었다. 관제일지는 약 9% 시선이 향하고 있는 것으로 분석되었다. 관제사의 시선이 향하는 영역은 대부분 정보를 수집하거나 제공하는 영역인데 반해, 관제일지는 정보를 기록하는 영역으로 집중적인 교통관리를 위해서는 정보 처리 및 제공에 업무가 집중되어야 할 것으로 판단된다.
