2000년 이후 국내 기관별 기록물 소장량의 지속적인 증가와 이에 대한 활용 요구가 증가하면서 기록물 기술 개선의 필요성이 제기되었다. 하지만 종이기록물에 대한 기술 개발 및 연구는 활발히 진행된 반면 영상기록물 기술 분야는 그 가치와 중요성은 인식되면서도 영상기록물의 다양성과 특수성으로 인해 전문적 기술 개발 및 연구가 미비하였다. 이에 본 연구에서는 영상기록물 기술의 개선 방향을 도출하기 위해 영상기록물 기술의 특수성 및 국내 영상기록물 기술현황, 해외 기록물 기술 사례 및 영상기록관리 전문가 대상 심층면담을 진행하였다. 이를 통해 영상기록물 정보 본질의 재규정 및 지속 연구, 디지로그적 관점의 영상기록물 기술 및 관리, 이용자 중심 기술 및 다양한 검색도구 개발, 연관정보 관리 강화로 영상기록물 가치창출, 영상기록물 생애주기를 관통하는 기술요소 관리 등의 개선 방향을 제안하였다.

영상의 확대는 영상의 확장과 보간의 단계로 설명할 수 있다. 영상의 확대에 있어서 영상의 정보의 부족으로 인하여 실질적인 해상도의 향상이 이루어지지 않는다. 본 논문에서는 확대 영상의 실질적인 해상도 향상을 위하여 확대영상의 향상 기법에 대하여 연구하였다.

본 연구는 초정리의 지역이미지통합 전략을 수립하는데 기초가 되는 지역이미지 및 중요요인에 대해 살펴보았다. 연구결과 지역이미지 통합을 위해 중요시 되는 요인은 자연성과 독창성이었으며, 인구통계적 특성에 따라 부분적으로 인식의 차이가 있는 것을 알 수 있었다. 이를 통해 지역이미지 통합을 위해서는 지역 대표자원을 이용해 자연적이면서, 차별화된 이미지통합 전략이 수립되어야 함을 알 수 있었다.

This thesis collected words, feelings, and psychological images expressed in female faces in their 20s and 60s. The comparative analysis of the characteristics will be based on the effective image of direction and improvement. Through the analyzed station of word of images collected, female faces in 20s of image are positive images such as pretty, cute, and elegant; however, there were also negative images such as gloomy, sharp, and stubborn. Female faces in 60s image are negative image such as scary, gloomy, sharp, and stubborn. To the analyzed station of word's tendency (usually expressed appearance), external-oriented tendency significantly developed in their 20s and 60s. It shows that the importance of appearance is emphasized in women face image in 20s and 60s.

In this paper, it proposes the technique to restore from a binary image in the color image. The color image is composed of three element images of red, green and blue. Therefore, the color image is first divided into a red, green, and blue element, and the Inverse Halftoning[2]$\sim$[4] is processed to each element images. Finally, each element images is collectively displayed. In that case, the Kalman filter was applied to the Inverse Halftoning for the restoration accuracy improvement of the image. As a result, it was possible to restore it in the color image as well as the time of a monochrome image. Moreover, the result that the restoration accuracy had improved even when which combining with the technique by using the Kalman filter for the Inverse Halftoning so far came out.

The remote sensing image server provides advanced image serving capabilities for geospatial image. Wide seamless image mosaics of Landsat 5 over GMS countries, which exceed a 15 GB or more in size per image, can integrate with other GIS map servers. The approach of two improvement algorithms leads to speed up the response time while preserving the data quality. This system does not only provide images on the web, but also provide GIS layers to WMS client map servers. The advantage of this approach is its efficiency lower cost in terms of cost, time and updating to obtain and utilize remote sensing image.

Purpose: When performing nuclear medicine examinations, body wraps or plastic supports are used to support and immobilize the patient's upper extremities to prevent patient safety accidents. However, the existing plastic supports compromised patient and staff safety, including finger entrapment and falls. Moreover, the body wrap provided by manufacturers compromised image quality such as upper extremities cutoff during whole body bone scan. Therefore, a new design of body wrap was developed to improve the issue, and this study aims to evaluate the usability of this medical body wrap. Materials and Methods: To evaluate the usability of the newly designed medical body wrap, a quality assessment of whole body bone scan images and a user satisfaction survey were conducted. Adult patients (male:female=129:152, age: 60.3±12.4 years, BMI: 24.0±4.2) aged 16 years or older who underwent a whole body bone scan during two periods: June to July 2022 (before improvement, n=139) and June to July 2023 (after improvement, n=142) were randomly selected for image quality evaluation. Five radiotechnologists visually evaluated the posterior view of the whole body bone image, including the left and right elbow (2 points), arm (2 points), whether the hand is extended (2 points), whether the hand is included (2 points), and the number of visible fingers (10 points), with a total of 18 points, which were converted to 100 points and analyzed for difference before and after improvement using an independent sample t-test. The user satisfaction questionnaire was evaluated using a 5-point Likert scale among 16 radiotechnologists from three general hospitals who experienced the new body wrap. Results: The image quality assessment was 82.0±13.8 before the improvement and 89.3±10.1 after the improvement, an average of 7.3 points higher, with a statistically significant difference (t=5.02, p<0.01). The user satisfaction survey showed an overall satisfaction rating of 4.1±0.8 for ease of use, 3.8±0.7 for scan preparation time, 3.9±0.7 for patient safety, 3.8±1.2 for scan accuracy, and 4.2±0.7 for recommendation (87.5% questionnaire response rate). Conclusion: The developed body wrap showed higher image quality and user satisfaction compared to the old method. Considering these results, it is deemed that the new body wrap may be more useful than existing methods.

Image segmentation is widely used in the pre-processing stage of image analysis and, therefore, the accuracy of image segmentation is important for performance of an image-based analysis system. An efficient image segmentation method is proposed, including a filtering process for super-pixels, improved saliency map information, and a merge process. The proposed algorithm removes areas that are not equal or of small size based on comparison of the area of smoothed superpixels in order to maintain generation of a similar size super pixel area. In addition, application of a bilateral filter to an existing saliency map that represents human visual attention allows improvement of separation between objects and background. Finally, a segmented result is obtained based on the suggested merging process without any prior knowledge or information. Performance of the proposed algorithm is verified experimentally.
