The edge preserving method is important for image storage and geometric transformation. In this paper, we propose a new edge preserving method using HOG-Guide filter for image segmentation. In our approach, we extract edge information using gradient histogram to set HOG guide line. Then, we use HOG guide line to smooth image. With two to four iterations of smoothing operations, we finally obtain desirable edge preserved image. Our experimental results showed good performances showing that our proposed method is better than other methods.

Since 2008, strategic partnerships have been established between China and Korea. From 2009 to 2019, the bilateral relationship kept a generally stable rate of development with conflicts and uncertainties. It is necessary to study national image construction in the respective mainstream media of the two countries. The present study analyzed Korea-related reports (N = 744) in the People's Daily from 2009 to 2019, aiming to examine the Korean national image framing under Fairclough's three-dimensional Critical Discourse Analysis (CDA) framework: "whatness," "how," and "whyness." The results shed light on what the Korean national image in the People's Daily was and how and why it was framed in that way. This study provided some implications for readers to further recognize the role that media play in constructing a particular image of one country and a frame for researchers to study foreign national image framing in one of China's mainstream newspapers.

This study investigated the effect of PR communication of local government on the relationship between the local government and the public and the image of the local government, focusing on the official blog of Busan Metropolitan City, 'Cool Busan.' It also examined the mediating role of organization-public relations. As a result, 'interactivity' and 'interest' among the characteristics of social media information have a statistically significant effect on organization-public relationship and municipal image. And balance' was found to affect the image of local government. In addition, the mediating role of the organization-public relations subfactors has been proved in the influence of the local government social media information characteristics on the local government image.

Multimedia searching is an important activity on the Web, especially among the younger generation. The purpose of this study aims to examine college students’ multimedia information needs and searching on the Internet. While there is a clear pattern among students with respect to their multimedia uses, searching sources, relevance criteria and searching barriers, some differences exist especially according to searching of different multimedia types such as image, audio and video. For multimedia uses, information/data-focused uses are frequently found in image and video, while the use of audio is mainly for object-focused searches. As multimedia searching sources, audio and video files present a similar pattern of being high in media specific searching sources and low in generic search engines. Browsing through related blogs and homepages is an important part of searching for media files accounting for approximately 20% of total search for each media. The relevance criteria used by study participants when search for image files was primarily concerned with topicality while the contextual and media quality in the audio and video types are also considered important. Searching barriers for audio and video files are categorized into three broad aspects, including access and search quality, preview limitations and collection limitations, while obstacles for image files searching include access difficulties and low qualities of various collection.

Language and letter are represented by a combination of its signifier and signified. All symblos are commonly calling direct attention to people who are living in the physical world. However, in cyberspace, the image takes control once inhabited by the language. Cyberspace with anonymity and deoent physical nature has something with physical laws. In this space the statue transcends the imaginary realm. Ideology gives a greater connotation by giving a series of regulation to images floating in cyberspace. Even if various media have the same image, the meaning of the image changes depending on which ideology is used. The impact of this on the public is great. In this study, I discuss the ideology in cyberspace where is supposedly wide open to who visits and spreads all the thoughts without suppression and the human body. The main ideas would be who owns the ideology and what does it want to control and how the people would react to the ideology. This paper would eventually head the prototype that visualizes above ideas. Though the interactive media it will also show the subject in the real world is accept the images floating in the cyberspace without any doubts.

Selfie practices on social media can result in negative body image for men. The current study investigated the dual body image pathway model for the relationship between selfie practices on social media and body satisfaction, with internalization as a mediator. Structural equation modeling analyses supported our research model when studying 446 young Korean male Instagram users. The results indicated that selfie editing behavior, but not selfie browsing behavior, significantly predicted an increased internalization of a body ideal. The positive associations between internalization, muscularity dissatisfaction, and body fat dissatisfaction were confirmed. Additionally, the indirect effects of selfie editing behavior on muscularity and body fat dissatisfaction due to internalization were significant. The study confirmed the detrimental effects of selfie behavior on body satisfaction for male social media users. The results provided valuable information that selfie editing may be a risky behavior since it can result in developing muscularity and body fat dissatisfaction. Theoretical contributions and practical implications were discussed. Future research should address the age and cultural differences that may elucidate the impacts of selfie practices on men's body image concerns.

The purpose of this study was to examine the effect of exposure to body image in media and bullet screen on weight loss intention by specifically focusing on Bilibili, a video sharing website of China. For the study, a 3 (Social viewing: no bullet screen vs. complimentary bullet screen vs. critical bullet screen) x 2 (Body image in media: ideal vs. realistic) between-subjects factorial design was conducted. A total of 310 Chinese women in their 20s were recruited to participate in an experimental survey. The main results showed that viewing the ideal body image with the complimentary bullet screen and realistic body image with the critical bullet screen strengthened the participants' intention on weight loss. Finally, the interaction effect of social viewing and the types of bullet screen were examined. The higher weight-loss intention was revealed when social viewing was conducted with the complimentary bullet screen of the ideal image. The results of this study can enhance the understanding of the bullet screen as a type of social viewing and its effect on user behavior intention.

Variation of the observer's viewing position is one of the major causes of image space distortion in the stereoscopic display. Especially, a large image distortion, which is caused by different depth direction positions of the observer's two eyes, is made by the observer's rotation movement in relation to the center of the screen. This is different from distortion of horizontal and depth directional movement of the observer. In this paper, we analyzed distortion of the image space due to the observer's rotation movement and showed the corrected result of distortion through simulation in the stereoscopic display. Finally, we showed that the distortion shape of the observer's rotation movement is different from horizontal and depth directional movement of the observer.

This study investigated the impact of appearance pressure from celebrities' social media upon internalization of mesomorphic ideal and muscularity dissatisfaction and the moderating role of time spent on social media in the relationships among variables in a sample of young Korean men (N=247). Those men who regularly participate in physical activities more than three times a week were included in our sample. Structural equation modeling analysis revealed that celebrities' social media pressure directly influenced both internalization and muscularity dissatisfaction, and internalization predicted muscularity dissatisfaction. A significant mediating effect of internalization in the relationships between celebrities' social media pressure and muscularity dissatisfaction was found. However, the moderating effect of time spent on social media was not found. The present results highlight the significant and negative effects of celebrities' social media on male's body image perception. By comparing the results of this study to previous studies, we can anticipate that the effects of social media on users' body image concerns can differ between male and female in the matter of time spent on social media. Implications of the study results and suggestions for future studies are discussed.
