In this paper we propose a new algorithm for detecting and counting flowers in a complex background based on digital images. The algorithm mainly includes the following parts: edge contour extraction of flowers, edge contour determination of overlapped flowers and flower counting. We use a contour detection technique in Computer Vision (CV) to extract the edge contours of flowers and propose an improved algorithm with a concave point detection technique to find accurate segmentation for overlapped flowers. In this process, we first use the polygon approximation to smooth edge contours and then adopt the second-order central moments to fit ellipse contours to determine whether edge contours overlap. To obtain accurate segmentation points, we calculate the curvature of each pixel point on the edge contours with an improved Curvature Scale Space (CSS) corner detector. Finally, we successively give three adaptive judgment criteria to detect and count flowers accurately and automatically. Both experimental results and the proposed evaluation indicators reveal that the proposed algorithm is more efficient for flower counting.

This study selects camellia flowers as a material for design development and created patterns by simplifying the image of camellia flowers and combining it with a geometrical motif. It it applied them to various fields to develop design content for fashion cultural products that were Korean, modern, and competitive. For this purpose, this paper used Adobe Illustrator CS2 to turn the camellia flower into a motif and develop it into a pattern. Based on the realistic form of camellia flower, this paper set 3 basic motifs of new formative images, using graphic elements, such as omission of a form, simplification, overlapping, repetition, and reduction, and it also developed two transformed motifs by applying a different color to each motif. This paper repetitively arranged each motif in the background of a diamond shape, a square, and a circle, and it combined each motif with the patterns of marcel, stairs, and stripes, through which it expressed the combination of the geometrical patterns and the flower patterns. Through the application of repetitive and combined patterns of each motif, the enlargement and reduction of motifs, the repetition of motifs, the combined use of motifs, and the change in colors and layout, this paper used the motifs of various fashion cultural products, such as scarves, neckties, and T-shirts.

This paper proposes a hybrid algorithm combining K-means clustering and watershed algorithms for flower segmentation and counting. We use the K-means clustering algorithm to obtain the main colors in a complex background according to the cluster centers and then take a color space transformation to extract pixel values for the hue, saturation, and value of flower color. Next, we apply the threshold segmentation technique to segment flowers precisely and obtain the binary image of flowers. Based on this, we take the Euclidean distance transformation to obtain the distance map and apply it to find the local maxima of the connected components. Afterward, the proposed algorithm adaptively determines a minimum distance between each peak and apply it to label connected components using the watershed segmentation with eight-connectivity. On a dataset of 30 images, the test results reveal that the proposed method is more efficient and precise for the counting of overlapped flowers ignoring the degree of overlap, number of overlap, and relatively irregular shape.

판단첨형식 연화문은 연꽃잎이 뾰족한 형태를 의미하는 것으로서 원형돌기식, 삼각돌기식, 판구곡절식 등과 더불어 백제의 대표적인 연화문 형식 중 하나이다. 이 연화문은 백제 한성기부터 사비기에 이르기까지 와당을 비롯한 불상 광배, 사리병, 두침 등에 다양하게 시문되었다. 그러나 현재 남아 있는 대부분의 판단첨형식 연화문은 사비기의 와당에 시문된 것이 대부분이다. 이들 연화문은 중국 북조나 남조, 고구려 등의 영향으로 제작된 것이 대부분이나 풍납토성 경당지구 출토와당, 용정리사지 출토 와당, 왕흥사지 출토 사리병 등에 시문된 연화문으로 볼 때 중국 북조의 영향이 절대적이었던 것으로 생각된다. 아울러 백제기에 나타난 여러 문양의 판단첨형식 연화문은 당시 백제의 활발한 문화교섭을 판단케 한다. 백제의 판단첨형식 연화문은 그 평면형태에 따라 보주형, 유엽형, 세장유엽형 등으로 구분할 수 있다. 보주형은 풍납토성 및 용정리사지에서 검출된 와당으로 그 시기는 한성기~웅진기의 것들이다. 반면, 유엽형 및 세장유엽형의 연화문은 무령왕릉 왕비두침, 은제탁잔, 서혈사지 와당, 구교리사지 와당, 하죽리 와당 등에서 확인되고 있어 웅진기 이후인 6세기 전반 이후의 연화문임을 추정케 한다. 현재 판단첨형 연화문 중 가장 이른 시기의 것은 풍납토성 경당지구에서 수습된 5세기 중반대의 것이다. 그러나 향후 점진적인 발굴조사를 통해 시기적으로 선행되는 와당이 수습될 가능성이 매우 높고 아울러 다른 다양한 형식도 출토될 여지가 적지 않다. 나아가 중국 남북조시기의 사지, 왕궁지, 기타 건물지의 발굴조사를 통해 다른 판단첨형식 연화문이 수습될 가능성도 적지 않다. 이는 그 동안 알려지지 않은 백제 판단첨형식 연화문의 계통을 파악하는 데에도 큰 도움이 될 수 있으리라 생각된다.

스카프는 인체의 보온 역할뿐만 아니라 여성 의복의 액세서리로서 큰 역할을 해 왔다. 오늘날 액세서리에 관한 관심이 높아지면서 스카프는 의복의 보조적 역할에서 벗어나 점차적으로 패션의 전체적 분위기를 이끌어 가는 주도적인 위치로 그 비중이 확대되었다. 그러나 우리나라의 스카프 디자인은 해외 브랜드에 대한 모방의 단계를 벗어나지 못하고 있는 실정이므로 이제는 우리만의 스카프 디자인을 개발해야만 한다. 따라서 본 연구에서는 한국적이면서 현대적인 감각을 살린 스카프 디자인을 개발하기 위하여 분청사기에 표현된 연꽃문양과 전통 조각보를 디자인 개발의 소재로 선택하였다. 분청사기에 표현된 연꽃문양의 형태는 사실적인 표현보다는 그 문양을 단순하게 또는 반추상적으로 표현한 것이 많고 조각보의 기하학적인 조형미는 현대 감각에 맞는 한국적인 이미지를 잘 표현한 소재이다. 먼저 분청사기에 나타난 연꽃문양과 조각보에 대한 자료 조사를 실시하여 기초 자료로 활용하였다. 그 중에서 현대적인 이미지를 잘 나타내는 것을 선정하여 컴퓨터 디자인 프로그램을 이용, 기본 패턴 세 가지를 구성하였다. 구성된 각 패턴을 가지고 정사각형 스카프 및 장방형 스카프를 각각 재구성하여 완성하였다.

These days, hair design is recognized as a kind of molding arts which peform expression skill to create personal self as well as practical skill. Recently, the efforts to express hair design sublimating it to art works have continued. For these reasons, this study had purposes as follows; First, it developed creative and original design producing works to shape the flower image that was an important material of hair design. Second, it presented the possibility to express the field of hair design with art. In the flow of age, nature has provided design with unlimited creative motive. Flowers, among various materials, show the nature's change, combination and order and impose diverse symbolic meanings. Therefore, flowers are good materials to express the works. Through the process of decolorizing and dyeing with hair, five works of nature's fragrance, hope, reed flowers, windflower, magnolia blossom had been produced. The results of the process were as follows; First, the transformation of shape through the simple process taking the image of shaping flower as subject matter could be a motive of new hair design art. Second, if the various images of flowers were expressed as hair art with three-dimensional shape, it could be works with value of beauty. Through the process of this study, it was proved that nature could be endless subject matter for art. Therefore, with continuous studies, it can be motive of developing designs in producing work activities of many hair designers. In addition, academic development will be achieved through wide and diverse studies.

This writing, focused on by Tarkovsky and by Song, Il-gon, examines moments of sage which is what Eliade described as 'hierophanic time'. These productions, which can be seen as movies that seek after the truth, show important paradoxical ideas and expressions in those moments. This is because symbolic messages from unrealistic and out of ordinary images are specifically shown. If they had to be compared, through the film by Tarkovsky, the technical civilization of contemporary society in an apocalyptic view is criticized and saved, or the prophetic will to not give up the desire for salvation is shown. In the process, the short shots which forces to show hierophanic time not only diversely visualized the author's ideological self-consciousness towards the conversion of the new world, but it also fulfills the metahistorical meanings mentioned by Eliade. However, in the film by Song, Il-gon, the realistic personal sufferings of three women is specifically shown first in extreme. They overcome their unsolvable problems through mysterious rituals and belief in miracles. In the scenes that include hierophanic time, there are many cases that cover Christian faith and the meaning of salvation. In other words, we can say that hierophanic time in , are related to conviction which led to moments of miracles in order to overcome reality. Therefore, even though there is a difference in the way authors use hierophanic time, the scenes that show it in the two movies display individuality of mythical imaginations disclosed by Eliade. This is because the general hope for reproduction, or meaningful symbols related to the ideal conversion of affairs are revealed.

This study is a discussion of the expressive characteristics of contemporary fashion design with floral images. It aims to help understand the overall trends of contemporary fashion design and textile motif design and expand the potential expression fields of originative design to natural objects such as flowers. Methodologically the study analyzed 976 pieces of data gathered from Haute Couture and Pr$\hat{e}$t-$\grave{a}$-Porter collections of 2005S/S-2009F/W, according to their types of expression. The study results show a share of 42.7% for plane type expressions by printing or weaving and a share of 51.5% for relief type expressions, compared with 5.7% for solid type expressions. However, those expressions represented elegant femininity with emphasis on formative beauty and were applied to fashion accessories or hair adornments. The expressive characteristics found from the analysis were represented by natural images, feminine elegance, and decorative aesthetics of handicrafts. Flowers in the contemporary fashion purify the internal emotions of humankind stand for personality and beauty in many different ways of expression and serve as a means of expressing more artistic values breaking out of stereotype.
