Image snapping for an image moves the cursor location to nearby features in the image, such as edges. In this paper, we propose geometric snapping for 3D triangular meshes, which is extended from image snapping. Similar to image snapping, geometric snapping also moves the cursor location naturally to a location which represents main geometric features in the 3D triangular meshes. Movement of cursor is based on the approximate curvatures which appear geometric features on the 3D triangular meshes. The proposed geometric snapping can be applied to extract main geometric features on 3D triangular meshes. Moreover, it can be applied to extract the geometric features of a tooth which are necessary for generating the occlusal surfaces in dental prostheses.

In recent years, natural healing space studies have been done in health care and forestry. However, previous studies have focused on healing effects of natural elements in interior space or natural landscape view. And there is a limit to using the evidence for healing space design. The aim of this study is to discover the relationship between types and effects of healing space for evidence-based design. This study compares and analyzes the mayor images, psychological restorativeness, and satisfaction to identify the effects and differences of natural trail, designed trail, natural shelter, and designed shelter by types of forest space. Collected data is analyzed with a factorial analysis, valiance analysis and multiple regression analysis in SPSS 18.0. The results of this study are as follows: 1) Among five factors consisting psychological restorativeness, natural trail can be achieved with 'being away' and 'compatibility' and designed shelter can be achieved with 'fascination' and 'coherence'., 2) Psychological restorativeness values higher in images with higher excitement, brightness, vitality, and beautifulness as well as in images with lower level of disorder., 3) Among five factors consisting psychological restorativeness, higher forest satisfaction can be achieved with a higher level of 'being away' and 'coherence'. In conclusion, this study contributes to providing fundamental information for design guidelines of healing spaces through identifying the characteristics of healing environment by types of forest space.

자연영상이나 스팸메일 영상으로부터 텍스트 영역을 추출하고 추출한 텍스트 영역에 이진화를 수행하고 나면 가로 방향이나 세로획 방향으로 놓여 있는 "1" 그리고 "ㅡ" 에 해당하는 한글의 종성부분이 이미지 내의 잡영을 지울 때 종종 지워지는 결과를 볼 수 있다. 이렇게 지워진 획 부분을 되살리기 위한 방법으로 텍스트 Hinting 알고리즘을 제안한다. 텍스트 Hinting 알고리즘은 이진화된 이미지의 텍스트 픽셀 위치와 동일한 좌표에 해당하는 원본 이미지의 RGB 값을 추출하여 추출된 텍스트 후보 영역의 색상을 알아낸다. 추출된 텍스트 색상 레이어 이미지와 이진화된 이미지에 OR연산을 수행하게 되면 지워진 획 부분을 복원할 수 있다. 제안한 방법을 스팸 이미지에 적용한 결과 텍스트 추출결과를 획기적으로 개선할 수 있음을 보였다.

본 논문은 비구조화된 이미지 저장소로부터 효과적인 이미지검색을 위한 객체 지향 검색 체계를 제시한다. 본 검색 체계에서는 이미지의 내용을 정량적 특성을 갖는 시각 정보, 비정량적 특성을 나타내는 의미 정보, 그리고 가장 추상적인 정보를 포함하는 키워드의 세 종류로 규정한다. 시각 정보와 키워드는 특별한 구조없이 집합의 형태로 저장하고, 의미 정보는 상속과 군집 관계를 갖는 계층구조로 저장하는 것이 자연스럽다. 본 논문에서는 객체지향 모델을 사용하여 비구조화된 이미지 저장소를 위한 통일된 검색 체게를 제시한다. 제안된 검색 체계의 효과를 검증하기 위해 많은 이미지 집합에 대한 실험을 수행하였다.

Text region detection from the natural scene images used in a variety of applications, many research are needed in this field. Recent research methods is to detect the text region using various algorithm which it is combination of edge based and connected component based. Therefore, this paper proposes an text region detection using edge and regional minima/maxima transformation algorithm from natural scene images, and then detect the connected components of edge and regional minima/maxima, labeling edge and regional minima/maxima connected components. Analysis the labeled regions and then detect a text candidate regions, each of detected text candidates combined and create a single text candidate image, Final text region validated by comparing the similarity and adjacency of individual characters, and then as the final text regions are detected. As the results of experiments, proposed algorithm improved the correctness of text regions detection using combined edge and regional minima/maxima connected components detection methods.

This study examined recycled fashion design utilizing natural images for application to recent trends. This study is significant in that it presents the possibility of the development of recycled women's wear design by reflecting the characteristics and expressions of natural images and using denim material, which is the most common clothing material for everyday life. The results of this study are summarized as follows. First, five types of women's clothing was produced, pursuing a natural design with a soft and feminine silhouette. Second, the colors used were blue and white, which could represent nature. Third, as for materials, this study used clothing that was to be thrown away: four pairs of denim pants and two denim dresses. This study chose denim cloth, with its great value for reuse, because of the characteristics of the strong and durable fiber, because everyone has more than one article of clothing made from denim and because it can be easily sourced. Fourth, for textile motifs, this study expressed a peaceful natural scenery with tropical animals and plants. In addition, this study further emphasized natural images using transfer media printing. This study has significance in that it presented the possibility of recycled fashion design and expanded the range of utilization using transfer media printing, a dyeing treatment to reduce the environmental burden.

The purpose of this study is to draw out the features of expressions about Nature in Korean interior design, because the Nature has been being very important theme in the interior space. So, the 68 cases of domestic famous interior designers' works during last ten years were selected from authorized design magazines like as INTERIORS, MARU and so on. And next, the cases were analysed in according to interior image style, design elements used for effect of Nature and the direction of expression(directly or indirectly), As the results, composite expressions with a few elements were found in modern, hi-tech, elegant, minimal and casual styles, while direct expressions with many elements were found in natural and ethnic styles. And main elements for effect of Nature were trees and stones. Among many elements, water and stones became more important elements after 2000 than before. In the meantime the use of composite expressions was being increased and so appeared even in natural and ethnic styles.
