  • The three dimensional(3D) reconstruction from two dimensional(2D) image data is using in many fields such as RPD(Rapid Product Development) and reverse engineering. In this paper, the main step of 3D reconstruction is comprised of two steps : image processing step and B-spline surface approximation step. In the image processing step, feature points of each cross-section are obtained by means of several image processing technologies. In the B-spline surface approximation step, using the data of feature points obtained in the image processing step, the control points of B-spline surface are obtained, which are used for IGES file of 3D CAD model.

  • Observation of microorganisms collected from contaminated soils has been mainly conducted by using microscopy. Microscopic measurement is occupied an important part of the microorganism experiment, and is used as an important tool to count microorganisms as well as to observe cellular form and mode of life in the field of soil microbe observation. In general, observation equipments for soil microbes consist of electron microscope, camera, frame grabber (image acquisition baud), and image analysis software. Because image analysis software should be linked with frame grabber most equipments have to be imported as the package form. Therefore, the observation system is very expensive and difficult to be operated. In this study, soil microbes' observation equipment with the vision system which is easy operated and cheaper than imported one was developed and tested. The efficiency of image capturing and data aquisition with developed frame grabber and software in this experiment was good enough to analyze the image of soil microorganism.

  • The research is done with reference to insurance industry. Three companies are taken for the study, first one is LIC, second is ICICI Prudential and third one is ING Vysya life insurance. The impact of advertising message was seen on the brand image of these companies. Six print ads were taken for each company and data was collected from five hundred and forty respondents and forming a sample size of thirty. Three questionnaires were prepared one for brand image before showing ad; second one for advertising message and third one for brand image after showing ads. Through this study these three companies were also compared on the ground of which company has the effect on its brand image by showing ads of that company before and after.

  • We proposed a new experimental method which is required to easily observe the growth behavior of fatigue cracks. In the proposed method, the image data of cracks were stored into the computer while the cyclic loading was interrupted. After testing, crack length was determined using an image processing software which was developed by authors. By comparing the data measured by the image processing system with those by the manual measurement with a microscope, the effectiveness of the image processing system was established. If the proposed method is used to monitor and observe the crack growth behavior automatically, the time and efforts for fatigue test could be dramatically reduced.

  • To improve the road transportation safety, the road traffic data is monitored by applying an image detection system. The road traffic safety is analysed using image processing techniques. For more accurate measurement, the coordinate matching of real road data to image is one of the most essential parts of the image detection technique. The road image is skewed at the input screen, because the video camera is installed at the roadside. A fast and precise algorithm for the coordinate matching is developed to convert image coordinates into road coordinates.

  • Instant custom embroidered souvenir manufacturing system was studied. Recently customers want to get individually specialized souvenir. We present a modular manufacturing system and implementation of image processing, conversion of punching data. The manufacturing system consist of main module, photographing module and U/I module. We can change the system easily through modularization. Image Processing was necessary for making punching data. We developed sketch typed image processing and image processing which used brightness. Brightness type is suitable for instant embroidered souvenir. This study showed that fusion of embroidery technology and image processing technology can make a new business successfully.

  • A study to develop generalized and systematically designed satellite image processing software system on mainframe computer was successfully carried out. Commercially available softwares such as LARSYS were analyzed and modified, and well known satellite data processing algorithms were implemented into comprehensive software. New algorithms were also presented and developed. The contents of developed softwere system may be divided into 8 major sections: menu and user interface, data file management, preprocessing, enhancement in monochrome image, multi-dimension image analysis, scene classification, image display/hardcopy, image handle utility software. Some additional software such as GIS and DBMS will make this software more comprehensive and generalized one for the satellite data processing.

  • 본 논문에서는 공작기계 등에서 필요로 하는 진직도 측정시스템을 가시광의 레이저와 CMOS 이미지센서를 사용하여 저가로 구현하였다. CMOS 이미지센서를 이용하여 광이미지를 검출하고 영상처리를 통해 진직도 변화를 계산하였다. 레이저와 이미지센서의 거리를 3m로 하여 실험한 진직도 측정에서 오차가 0.9%로 우수함을 확인하였으며, 제작된 진직도 시스템은 3D 프린터 등 다른 응용분야에서도 사용 할 수 있을 것으로 생각된다.

  • In this paper, we develop a galaxy image classification method based on hand-crafted features and machine learning techniques. Additionally, we provide an empirical analysis to reveal which combination of the techniques is effective for galaxy image classification. To achieve this, we developed a framework which consists of four modules such as preprocessing, feature extraction, feature post-processing, and classification. Finally, we found that the best technique for galaxy image classification is a method to use a median filter, ORB vector features and a voting classifier based on RBF SVM, random forest and logistic regression. The final method is efficient so we believe that it is applicable to embedded environments.

  • The number of international tourists is noticeably recovering in many parts of the world, with the number of Vietnamese tourists growing significantly. Consequently, this study aims to identify the factors influencing the image of Vietnam's tourist destinations among international tourists interested in visiting the country. Additionally, the study examines whether the perception formed in this manner subsequently affects their intention to visit. The findings reveal that cultural attractions and eWOM (Electronic Word of Mouth) positively influence the development of a tourism destination image. However, film tourism did not have a significant effect on the destination image. Moreover, it was observed that the destination image indeed influences the intention to visit.
