With supplied computers and the development of information and communication thropugh the Internet, the space of personal home pages in potal sites has been filled with photos taken by digital cameras, and 'the introduction of privacy' done in the personal home pages has become a general trend in society. As the use of Photoshop, available to edit and modify digital photos, in this social atmosphere, has grown general, they have shown their interest in the retouching technique of Photoshop. Computer graphics, marked based on the treatment of a variety of information into pictures or a technology to mark it, recently various application methods have been found in make-up. Especially, Adobe Photoshop, used to edit and modify images, is a sofetware program proper to perform beauty make-up in correcting and creating images in an effective way. The purpose of this study is to express each factor in Adobe Photoshop CS2 about the beauty make-up. As a result, I can say, the process that digital image is retouched by Adobe Photoshop CS is similar work to beauty make-up. The process of Photoshop retouching can be used as the materials for educating of make-up and as the materials for presentation of beauty make-up trend. And also we can serve the simulation to the customer before real make-up. Therefore, this study is for the effective performance of diverse beauty makeup integrating retouch technique with Photoshop CS.

Materials used for repairing and restoring both pottery and porcelain are practically organic, which makes the analysis procedure difficult in the course of time. It is, however, important in the field of conservation to analyze the material applied in the past. In consequence, this research will examine the components of the restoration materials collected in the process of ceramic conservation: the fillings using SEM-EDS and FT-IR; retouching materials; the adhesive used between the filling and retouching material.

인터넷 쇼핑몰, 오프라인 매장에서 구입한 제품의 포토 리뷰를 블로그, 쇼핑몰에 올릴 때 얼굴 노출을 꺼려하여 직접 사진 처리 프로그램 등을 통해 얼굴을 가리거나 사진을 얼굴 부분까지 잘라 내는 등의 번거로운 작업을 거친 후 올리게 된다. 위와 같은 불편함을 해결하기 위해 쇼핑몰, 블로그 등 인터넷 매체를 통해 포토 리뷰를 작성 할 때 얼굴이 포함된 사진을 올리더라도 자동으로 얼굴 인식 후 의상에 어울리는 소품을 합성하여 구매자가 포토 리뷰를 올리기 편한 환경을 제공하고자 한다. 이를 위해 기본적인 얼굴 추적과 얼굴 특징 점을 기반으로 한 안경과 같은 소품 합성 등이 필요하다. 본 연구에서는 실시간으로 얼굴 및 특징점을 추출하고 이를 기반으로 얼굴에 소품을 합성하는 기본 기능을 구현하였다.

In this study, we compare the properties and estimate the durability of five oil colors that are the most popularly used colors in the conservation of oil paintings. A set of these colors was obtained form four manufacturers each, and their properties were analyzed by conducting deterioration experiments. Subsequently, we observed the colors and performed X-ray fluorescence analysis. As a result of colour observation and XRF analysis, it was confirmed that there are the differences according to the pigment types, mixing rations and the manufacturers even for colors having the same product name. The deterioration test indicated differences in the appearance of the colors ; for instance, the color difference was above 12.0 in most of the samples, including restoration color and acrylic gouache. In the case of Lemon Yellow a lot of discoloration and cracking occurred, and difference in gloss was ob served in Viridian of manufacturer C. Most cracks were ob served in the restoration color obtained from manufacturer B and were assumed to be because of the resin used by the manufacturer. Nevertheless, additional research will have to be conducted by controlling variables in order to find out the cause. Through this study, we demonstrated that retouching materials for conservation of oil painting differed in their physical properties according to the color and manufacturer. Therefore a conservator should be mindful during the selection and use of materials for retouching oil paintings.

We propose a retouching method that converts a photography taken by smartphone to a watercolor painting image using bilateral filtering and mean shift segmentation which are mostly used in image processing. The first step is to convert an input image to fit the screen resolution of smartphone. And next step is to weaken high frequency components of the image, while preserving the edge of image using the bilateral filtering. And after that we perform mean shift segmentation from the bilateral filtered image. We apply parameters of mean shift segmentation considering the processing speed of smartphone. Experimental result shows that our method can be applied to various types of image and bring better result.

The purpose of this study is to investigate the characteristics of the mind maps which were drawn with pencil or color pens by elementary students. For this study, 31 students of the 6th grade were selected and trained mind mapping. After training, the subjects had drawn mind maps with color pens about the ROCK for 15minutes and drew mind maps with pencil after 2days of mind mapping using color pens. In addition to activities of mind mapping, the students handed in their papers which were written one's impression of drawing two kinds of mind mapping. The results were follows: First, in central circle which was linked words connected firstly with ROCK as key word, the difference of 2kinds mind maps were little showed in the quantity and quality of the words, branches and their adequacy. Second, the mind maps using pencils had more words, branches and images than mind maps of using color pens in the whole assessment. Third, the most students suggested that the mind mapping using pencil were advantage to economy of time, retouching words and branches, also the mind mapping using pencil made the students relax the strain for drawing it because of retouching possibility. Consequently, the results of this study suggest the mind mapping using pencil has advantage effect on the purpose of gaining students' thinking abundantly and economy of time in elementary science classes.

We propose a retouching method that converts a general photography to a watercolor painting image using bilateral filtering and mean shift segmentation which are mostly used in image processing. The first step is to weaken high frequency components of the image, while preserving the edge of image using the bilateral filtering. And after that we perform DoG(Difference of Gradient) edge extraction and mean shift segmentation respectively from the bilateral filtered image. The DoG edge extraction is performed using luminance component of the image whose RGB color space is transformed into CIELAB space. Experimental result shows that our method can be applied to various types of image and bring better result, especially against the photo taken in daylight.

본 논문에서는 영상처리에서 많이 사용하는 bilateral filtering과 mean shift segmentation을 이용하여 일반적인 사진을 수채화 스타일로 변환하는 기법에 대하여 제안한다. 먼저 bilateral filtering을 이용하여 사진의 외곽선 부분은 보존하면서 고주파 성분을 약화시키도록 한다. 그리고 bilateral filtering된 영상에서 mean shift segmentation을 수행하여 수채화 스타일의 영상을 생성한다. 본 논문에서 제안하는 기법으로 다양한 사진에 대하여 실험한 결과 수채화 스타일로 잘 변화되는 것을 확인하였으며 특히 주광에서 촬영한 풍경 사진들에 대하여 보다 우수한 성능을 보임을 확인하였다.

Previous research for visual assessment of streetscape employed static simulation methods to represent future landscape. However, streetscape is experienced sequentially, and thus dynamic simulations can be more effective. This study tried to adopt computer animation in the evaluation of streetscape, and examined its effects and possibilities. Three development scenarios for the redevelopment districts of Sokong-Ro and Banpo-Ro in Seoul were designed, and simulations were produced by three methods-photo-retouching, computer still image, and animation. A preference questionnaire was asked to 69 university students, and the effects of simulation methods on visual preference were examined. In addition, the frames of the animation were reclassed to identify the visibility of physical elements. The relationships between the visibility and visual preference were analyzed. The results showed that visual preference can be explained by three factors-Amenity, Tidiness, and Variousness-that account for 62.4% of the total variance, and the Amenity showed the highest proportion: 36.0%. Among the three simulation methods, animation showed the largest difference in preference for the most important factor(Amenity), and yielded the highest correlation between visibility of physical elements and Amenity. This result demonstrated that dynamic simulations can provide more accurate observation of visual changes, especially because the simulated landscape is experienced sequentially. The results also revealed that the sequential change in the visibility of physical elements can be examined easily and precisely by animation. This benefit of animation enables analysts to identify the points where the landscape varies the most, and thus visual preference should be evaluated.
