  • In Analysis of Fragmentation of rock blasted, The photo analysis method has been mainly used and these image acquisitions are mainly obtained by digital image from the front of the crushed rock. However, Image analysis is basically advantage of the image of planar shooting not front shooting but There is no way to take a photograph of huge plane rock slope. Thus, Unavoidably It is resolved by distorting or extending the image filmed at the front as well as adjusting it similar to its angle of plane shooting. Lately, With advancing unmanned aerial vehicle, It can simply image the fragment conditions of blasted rock of a high-definition digital image and Through it, It can acquire the most planar image to angle which accumulate cataclastic rock and also can make image analysis. In this study, It has been confirmed that tolerance value of analysis result of image filmed flatly is markedly lower than the existing front filmed image.

  • 본 논문에서는 RAW 이미지 포맷 중 PEF, MRW에 대한 분석 결과와 RAWImage Viewer에 대해 소개한다. DSLR 디지털 카메라로 촬영되는 이미지 파일은 범용의 JPEG 포맷이나 제조사별 독자적인 RAW 이미지 포맷으로 저장된다. 이러한 RAW 이미지 파일을 PMP 등의 휴대용 멀티미디어 기기나 디지털액자에서 재생 및 확인하기 위한 요구가 증대되고 있다. 하지만, RAW 이미지 포맷이 디지털 카메라 제조사별로 다르고, 해당 포맷에 대한 구체적인 정보가 공개되지 않아 대부분의 휴대용 멀티미디어 기기에서 RAW 이미지 파일 재생 기능을 완벽하게 지원하지 못하고 있다. 본 논문에서는 RAW 이미지 파일 포맷을 분석하여 다양한 임베디드 멀티미디어 기기에서 모든 RAW 이미지 파일을 지원할 수 있는 라이브러리 구축을 위한 연구 결과 중 일부를 소개한다. Cannon의 CRW, CR2 포맷과 Nikon의 NEF 분석 결과에 이어 PEF, MRW에 대한 분석 결과와 RAW 이미지 출력 및 분석 기능이 포함된 RAWImage Viewer에 대해 설명한다. 연구 결과는 RAW 파일을 재생할 수 있는 임베디드 장비 및 PC용 RAW 이미지 파일 재생 라이브러리를 구축 및 응용 프로그램 개발시 활용될 것이다.

  • The objective of this study was to investigate satisfaction and revisit intention of Muju Firefly Festival visitors, based on visitors’ evaluation of festival images. The result of this research provided three major findings as belows. 1. The factor of “uniqueness of festival” among emotional image group and the factors of “festival spirit” and “educational impact” among cognitive image group contributed to the levels of visitor satisfaction. 2. The factors of “uniqueness of festival” and “traditionalism of festival” among emotional image group and the factors of “festival spirit” and “educational impact of festival” among cognitive image group influenced the revisit intention of festival visitors. 3. The factor of “uniqueness of festival” among emotional image group and factors of “festival spirit” and “educational impact” among cognitive image group had an impact on the intention of word of mouth.

  • This research studied the role of images between visual thinking and analytic thinking to contribute to the ongoing discussion of visual thinking and analytic thinking and images in mathematics education. In this study, we investigated the thinking processes of mathematically gifted students who solved tasks generalizing patterns and we analyzed how images affected problem solving. We found that the students constructed concrete images of each cases and dynamic images and pattern images from transforming the concrete images. In addition, we investigated how images were constructed and transformed and what were the roles of images between visual thinking and analytic thinking. The results showed that images were constructed, transformed, and sophisticated through interaction of visual thinking and analytic thinking. And we could identify that images played central roles in moving from visual thinking to analytic thinking and from analytic thinking to visual thinking.

  • This study researched text mining and text network analysis to analyze the images of Nonghyup Insurance for consumers. With the recent development of social media, many texts are being produced and reproduced, and texts of social media provide important information to companies. Text mining and text network analysis are used in many studies to identify image of company and product. As a result of the text analysis, the positive image of the Nonghyup Insurance is safety and stability. Negative images of the Nonghyup Insurance is concern and anxiety. As a result of the textual network analysis, Centered mage of Nonghyup Insurance is safety and concern. This paper allows researchers to extract several lessons learned that are important for the text mining and text network analysis.

  • 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.

  • A positive destination image has an impact on the tourist arrivals and economic growth of the tourist destination. Recently, the content generated by sharing tourist experiences and destination information on the internet has been increasing. The online content has the potential to become a major tourist decision source and provide more in-depth materials and richer content to extract destination image, insight and tourist's perceptions of the destination. This study was designed to explore the destination image of Daegu online and draw lessons for successful image management in an era of big data. Text mining approach and social network analysis were conducted to extract destination image determining elements and assess the influence of the elements. The result showed that destination image elements related to tourist infra-structures and culture, history and art affected the overall destination image of Daegu. Destination marketers should make an effort to grasp these precise destination image and seek ways to boost competitiveness as a tourist destination.

  • Recently, digital images are extremely forged by editors or advertisers. Also, amateurs can modify images throughout easy editing programs. In this study, we propose identification and analytical methods for the modified images to figure out those problems. In modified image analysis, we classify two parts; a filtering change and a geometric change. Those changes have an algorithm based on interpolation so that we propose the algorithm which is able to analyze a trace on a modified area. With this algorithm, we implement a detection map of interpolation using minimum filter, laplacian algorithm, and maximum filter. We apply the proposed algorithm to modified image and are able to analyze its modified trace using the detection map.
