This study is on the strategy for establishing successful corporate brand image, by understanding the need for increasing brand value based on the level of brand recognition. In order to carry this out, the PICS (Product Image Concentration System) is suggested, which includes Brand Image Analysis on a high-level, Product Image Programming based on the result of the image analysis, and Product Image Coherency Assessment and Management, resulting in setting up a guideline for gaining competitive advantage and brand management. Brand Image Analysis is a method that utilizes image association to understand brand disposition by analyzing the association pattern among available visual materials to measure the corporate and brand image inclinations. As the next step, Product Image Programming establishes design philosophy and principles based on the analysis of brand image, and the Visual Programming is a process for visualizing the intended product image direction. Lastly, Product Image Coherency Assessment examines whether to incorporate design philosophy and principles or not to arrive at an agreed evaluation criteria for developing designs coherent with the brand image. The PICS (Product Image Concentration System) is a practical method for increasing a company' competitive advantage and managing brand. The expectation on this system is to provide a guideline for applying brand image in design process more objectively. For further study, diversification of image spectrum based on expressive keywords and comparative analysis on images as well as a product image interpretation program to understand the order of visual materials will be necessary.

공유저작물을 이용하는데 있어서 권리관리정보(RMI, Rights Management information)를 제대로 파악하지 못하거나 제대로 된 정보를 제공 받지 못하는 경우 이용자들은 저작권분쟁에 휘말릴 수 있다. 이러한 이유로 공유저작물을 제공하는 사이트에서는 공유저작물에 대한 정확하고 최신의 RMI 정보를 제공하기 위하여 통합하여 관리하고 최신의 정보로 갱신해야 한다. 하지만 동일한 권리를 가진 이미지는 다양한 이미지 포맷과 사이즈 변경에 따라 다른 형태로 유통되기 때문에 이에 대한 갱신처리가 중요하다. 본 논문에서는 이미지 특징점 기술을 활용하여 권리관리정보에 대한 중복데이터 문제를 해결할 수 있는 기법을 제시한다.

In this study, cable tension was measured using the vibration method, and a vision-based system was applied as a sensor to measure the displacement response of a cable in a non-contact method. In the vision-based system, the camera is installed in a location that considers the target structure and the field of view of the camera. However, it can be difficult to recognize the control points required to measure the displacement response of a structure as the target structure and other structures such as vehicles may be included in the image at the intended installation location. In this study, a distorted image including a vehicle shows inaccurate results in image analysis due to the installation position of the vision-based system. Accordingly, the image including the vehicle was eliminated by calculating the similarity between the two images. To verify the validity of the method of estimating the cable tension of cable-stayed bridges using the proposed method, the vibration method was applied to cable-stayed bridges in service to measure the tension.

최근 들어 무선 멀티미디어 서비스를 위한 Wireless Sensor Network 에 관한 연구가 활발히 진행됨에 따라 그 응용의 한 부분으로써 이미지 센서를 이용하여 이미지 데이터를 전송하는 WISN(Wireless Image Sensor Networks) 에 관한 연구가 시작되었다. WISN은 센서노드의 제한된 자원(배터리, 대역폭, 처리속도, 메모리 크기)으로 인해 많은 어려움을 갖는다. 특히 그 중에서 제한된 배터리로 인해 이미지 센서노드는 효율적인 에너지 관리가 필요하다. 이미지 센서노드의 에너지 소모는 이미지 캡쳐 과정, 이미지 데이터의 처리 및 가공(compression)과정, 이미지 데이터의 전송 과정에서 발생한다. 또한 수 Kbyte 이미지 데이터는 기존의 무선센서 네트워크의 데이터보다 훨씬 크기 때문에 빈번한 이미지 데이터의 전송은 노드의 수명을 단축시켜 전체 네트워크의 분단을 초래한다. 본 논문에서는 이러한 문제점을 해결하기 위해 JPEG 이미지 크기의 변화량을 고려하여 전송 횟 수를 최소화하는 기법을 제안한다. 종단 센서노드는 자신이 이전 JPEG이미지와 현재 JPEG이미지의 크기를 비교하여 특정 임계값 이하이면 전송하지 않고, 임계값 이상일 때에는 변화된 특정 부분의 이미지만을 보냄으로써 데이터량을 줄이게 된다. 결과적으로 효율적 에너지 관리를 통해 센서 노드의 라이프타임을 향상 시키는 결과를 가진다. 제안된 기법을 검증하기 위하여 테스트 보드를 만들어 제안된 기법과 일반적인 방법에서의 데이터의 전송 횟수 및 에너지 소모량과 노드의 라이프타임을 비교하여 제안된 기법의 성능의 우수함을 보였다.

In this study, the crack detecting system with digital image processing techniques based on the mathematical morphology method was developed to detect cracks in concrete structures. In the developed system, the image combining technique of reconstructing multiple images as an entire single image considering efficient management of analysis results was applied as an additional module. The developed system was verified through a field test with the cracked concrete culvert and the crack width of 0.2 mm was able to be detected in the 40m span. In the image analysis, the difference between calculated crack width and actual crack width were less than 0.08mm. For image combination in the stitching test of pattern images, the stitched image was identical with the original picture of entire subject in the visual perception level.

This study examined image restoration strategies of political parties regarding the Presidential impeachment In Korea. The analytic framework of this study was Benoit's rhetorical theory of image restoration strategies. Results showed that both Hanara Party and Minju Party used attack accuser as a major image restoration strategy. However, Hanara Party changed their strategies from attack accuser to future oriented. Thus, Hanara Party's image restoration strategy successfully applied Coombs theory, which future oriented strategy was good for an organization of the high responsibility in the context of crisis situation.

The existing ship repair tool management system based on hand writing has many problems such as frequent loss of tool and overdue. To solve this problem, same systems have adopted the bar-code system. However, the systems can't cope with a problem to substitute spurious tool for genuine one on bar-code damage. Therefore, additional validation steps are necessary in order to manage expensive ship repair tool. In this paper, we propose an image comparison method for ship repair tool management. To be more concrete, we propose a normalization method and determination conditions for image comparison to use characteristics of mobile device. The normalization method makes use of the characteristics of mobile device that provides functions of real time recording, overlapping and cropping images. The proposed method applies three conditions(sum of inner angles, size of angle, position of corner coordinates) into the comparison module. The implemented system shows good performance on change direction, lighting, size and etc. The accuracy is more than 95%.
