  • 본 논문에서는 MPEG2(Moving Picture Expert Group 2)비디오 디코더에서 영상데이타를 디코딩하는 기술에 관한 것으로, 종래의 동여상 처리기에서는 허프만 코드화 처리를 하여 정지영상을 부호화한후 분할기반 부호화 방식의 동영상 처리기법을 사용하였으나 1프레임의 코드화시에도 많은 계산 알고리즘이 필요하고 이미지의 닮음정도를 객관적수치로 표현할 수 없으므로 비슷한 이미지를 중복 코드화 작업 및 전송 작업을 하는 결함이 있었다. 본 눈문에서는 이를 해결하기 위하여 이미지의 닮음정도를 수치화하고 기준값 이하의 영상은 코드화 작업을 하지않고 계산된 영상 변화값에 의해 구현된 영상으로 대체하여 저장 및 전송하도록 하여 시각적으로 전혀 거부감이 없는 동영상을 구현하였다.

  • This study investigates the effectiveness of fashion coordination presentation formats when people buy apparel products online. This study conducted an online survey with 595 females who shopped online at the simulated website by a single apparel plan picture (n=189), coordination plane picture (n=187), and 3-D coordination image (n=216). For data analysis, factor analysis, Cronbach's alpha, MANCOVA, ANOVA, Duncan test, correlation analysis, and chi-square are used. The results of this study are: First, the hedonic shopping value was significantly the highest when respondents shopped at a 3-D coordination image shopping mall, the next highest-scored presentation type was the coordination plane picture, and the case of presenting only the single apparel picture was significantly the lowest. The utilitarian shopping value and information shopping value were higher in the coordination plane picture and the 3-D coordination image shopping mall than the single apparel picture. Second, transactions satisfaction was high when respondents shopped at a 3-D coordination image, coordination plane image, and single apparel image in decreasing order.

  • 어린이그림책에 표현된 일러스트레이션은 하나의 화면뿐만 아니라 화면과 화면의 조화로운 연결로 그림책의 줄거리와 내용을 전달한다. 그림책화면에는 빈 여백과 형태, 질감과 색채, 그리고 공간감 등의 구성요소들이 있어 화면상에 놓여진 위치에 따라 어린이에게 다양한 정서와 감동을 준다. 따라서 어린이그림책에는 자연스러운 이야기 내용과 함께 통일성과 리듬감 있는 구성요소로 화면의 흐름을 전달하는 연속성이 있다. 화면의 연속성은 글과 그림, 화면과 화면, 그리고 화면 내에서 그림의 연결에 따른 시각적 연상으로 이미지전달을 가능하게 하며, 어린이가 이야기 내용을 이해할 수 있도록 한다. 본 연구는 그림책화면의 연속성을 연구 분석함으로써 개성과 창의성을 바탕으로 제작되는 어린이그림책화면의 조화로운 연결에 대한 올바른 표현방향을 제시한다.

  • The mobile social networking application Instagram is a well-known platform for sharing photos and videos. Since it is folksonomy-oriented, it provides the possibility for image indexing and knowledge representation through the assignment of hashtags to posted content. The purpose of this study is to analyze how Instagram users tag their pictures regarding different kinds of picture and hashtag categories. For such a content analysis, a distinction is made between Food, Pets, Selfies, Friends, Activity, Art, Fashion, Quotes (captioned photos), Landscape, and Architecture image categories as well as Content-relatedness (ofness, aboutness, and iconology), Emotiveness, Isness, Performativeness, Fakeness, "Insta"-Tags, and Sentences as hashtag categories. Altogether, 14,649 hashtags of 1,000 Instagram images were intellectually analyzed (100 pictures for each image category). Research questions are stated as follows: RQ1: Are there any differences in relative frequencies of hashtags in the picture categories? On average the number of hashtags per picture is 15. Lowest average values received the categories Selfie (average 10.9 tags per picture) and Friends (average 11.7 tags per picture); for highest, the categories Pet (average 18.6 tags), Fashion (average 17.6 tags), and Landscape (average 16.8 tags). RQ2: Given a picture category, what is the distribution of hashtag categories; and given a hashtag category, what is the distribution of picture categories? 60.20% of all hashtags were classified into the category Content-relatedness. Categories Emotiveness (about 4.38%) and Sentences (0.99%) were less often frequent. RQ3: Is there any association between image categories and hashtag categories? A statistically significant association between hashtag categories and image categories on Instagram exists, as a chi-square test of independence shows. This study enables a first broad overview on the tagging behavior of Instagram users and is not limited to a specific hashtag or picture motive, like previous studies.

  • The stereoscopic three-dimensional (3D) display provides a 3D image by inducing binocular disparity for the observers who wear special glasses. With the rapid progress in flat panel display technologies, the stereoscopic 3D display is becoming a new benefit-model of the current display industry, and several kinds of commercial stereoscopic 3D products have been released and are attracting people. Nowadays, the motion picture quality of the 3D image becomes as important as resolution or luminance since most of the commercial 3D products are 3D televisions or 3D monitors which are required to display a clear motion 3D image. In this paper, an analysis and simulation of the motion picture quality of stereoscopic 3D image is proposed, and a comparison of the motion picture performance among the current stereoscopic 3D technologies is also provided.

  • Silver paste curing process is very important in LCoS panel manufacture because incomplete curing process will cause poor bonding strength and increase resistance. The imperfection situation results in poor reliability and the variation of the common voltage, respectively. The change of the common voltage causes image flicker. According to Kinetics, we acquire activation energy by using dynamic DSC and compare two kinds of silver paste. From the result of isothermal DSC, we get optimum curing parameters to solve the flicker problem caused of incomplete curing of the silver paste.

  • In this paper we propose a haptic interaction system that physically represents the underlying geometry of objects displayed in a 2D picture, i.e., a digital image. To obtain the object's geometry displayed in the picture, we estimate the physical transformation between the object plane and the image plane based on homographic information. We then calculate the rotated surface normal vector of the object's face and place it on the corresponding part in the 2D image. The purpose of this setup is to create a force that can be rendered along with the image without distorting the visual information. We evaluated the proposed haptic rendering system using a set of pictures of objects with different orientations. The experimental results show that the participants reliably identified the geometric configuration by touching the object in the picture. We conclude this paper with a set of applications.
