The article examines one of the most important means of visualization of mass information on the Internet - information graphics in the broadest sense of the term as a visual technology for presenting mass information. The main objectives of the article are to determine the genre-typological features of infographics and basic technological principles; identification of features of creation and use of information graphics in modern network. Certain benefits of online infographic editors include savings in resources and time. They allow the user, who has basic PC skills, to create standardized infographics based on their own data. In addition, the use of online services develops visual thinking, allows you to get an idea of quality criteria and current trends in infographics, as well as to gain initial experience in the visual presentation of data.

현재의 복잡한 시각문화는 디지털 기술의 발전에 따라 이미지, 그래픽, 사진, 영화, 텔레비전 등의 영상에 따른 광범위하게 확대된 시각 세계이며, 사운드와 문자까지를 삽입하여 의미 내용을 전달하기 때문에 일반적인 언어나 문자를 넘어 정보를 전달하고 커뮤니케이션 하는 멀티미디어 적 성격을 갖는다고 할 수 있다. 이 때의 다양한 이미지들을 보는 시각은 언어와 불가분 하게 연결되며, 이미지와 시각의 상상적 질서가 문화적, 역사적으로 특정한 방식으로 구성된다고 할 수 있다. 언어는 그 시대의 사회, 문화, 역사에 따라 다르기 때문에 시각적 경험이 부분적으로라도 언어적으로 매개된다면 시각적 경험이 보편성을 갖기는 어려운 것이다. 따라서 시각 체계들간의 사회 문화적 차이를 형성하고 규정하는데 에는 언어적 질서의 역할이 크다고 할 수 있다. 이러한 시각 언어와 함께 역사적으로 다양한 시각적, 광학적 장치들 또한 많은 영향을 끼쳤는데 이 시각적 테크놀로지들은 가시적 세계 속에서 주체와 주체의 가시적인 대상들과 관계 맺는 방식을 결정하는 구체적인 물질적 실천체인 것이다. 시각언어는 이렇게 이미지들의 표상이라는 차원과 일련의 역사적인 물질적, 제도적 실천들로의 시각테크놀로지라는 차원이 결합된 것이며, 이것이 하나의 시각체제 내에서의 대상 세계를 보는 사회적인 시각 양식을 결정하였다. 따라서 본 연구는 미디어테크놀로지의 발전에 따라 변화된 개념이나 특성들에 따라 시각언어를 사회적이고 역사적인 성격을 가진 것으로 이해하고 표상의 차원으로서의 시각언어와 제도적이고 물질적인 실천으로서의 시각 테크놀로지의 차원에서 설명했다. 결국 시각 테크놀로지는 그 기능과 시각 양식에 대한 영향은 그것의 기술적 요소만으로는 설명할 수 없으며, 그것과 결부된 담론적 실천들과 물질적 제도적 실천과 분리될 수 없다. 특정 테크놀로지의 기술적 요소가 담고 있는 가능성 역시 그대로 실현되는 것이 아니라 항상 사회적 맥락에 의해 그 효과가 매개되고 제약되면서 실현된다고 할 수 있다.

본 연구의 목적은 초등학교 도덕 교과서에 포함된 매체를 정보처리모형을 활용하여 분석하고, 학교도서관 입장에서 매체활용능력 향상 방안을 제안하는 것이다. 이를 위하여 초등학교 4 5 6학년이 배우는 국정도덕 교과서 3권을 분석하였다. 분석 결과 초등학교 도덕 교과서의 투입 요소는 사진(시각매체)과 이야기(인쇄매체)에 편중되어 있고, 처리 요소는 조사와 표를 이용한 학습지 중심이며, 산출 요소는 글쓰기, 말하기, 제작(창작)을 중심으로 이루어지고 있는 것으로 나타났다. 그러나 투입 요소인 매체를 활용하여 적절한 학습정보를 획득할 수 있는 구체적인 활동이 부족하고, 투입 요소로 많이 출현하고 있는 시각매체의 읽기 전략도 부족한 실정이다. 투입 요소의 편향과 정보 처리 활동의 제한 등의 문제를 해결하고 매체활용능력을 신장하기 위해서 학교도서관은 독서흥미발달단계를 고려한 다양한 독서자료의 제공, 텍스트 유형에 따른 학습지 개발, 협동수업시간 확보 등을 위해서 노력해야 할 것으로 보인다.

Facial model reconstruction and surgical simulation are essential parts in the computer-aided surgical system. Plastic surgeons use it to design appropriate repair plans and procedures before actual surgery is operated. In this work, the exploration of 3-D metamorphosis to them presents new results in these two parts.

Homogeneous but distinct visual objects having low-contrast boundaries are usually merged in most of the segmentation algorithms. To alleviate this problem, an efficient image segmentation algorithm based on a bottom-up approach is proposed by using spatial domain information only. For initial image segmentation, we adopt an efficient marker extraction algorithm conforming to the human visual system. Then, two region-merging algorithms are successively applied so that homogeneous visual objects can be represented as simple as possible without destroying low-contrast real boundaries among them. The resultant segmentation describes homogeneous visual objects with few regions while preserving semantic object shapes well. Finally, a size-based region decision procedure may be applied to represent complex visual objects simpler, if their precise semantic contents are not necessary. Experimental results show that the proposed image segmentation algorithm represents homogeneous visual objects with a few regions and describes complex visual objects with a marginal number of regions with well-preserved semantic object shapes.

Social media play a significant role in communicating information across the globe, connecting with loved ones, getting the news, communicating ideas, etc. However, a group of people uses social media to spread fake information, which has a bad impact on society. Therefore, minimizing fake news and its detection are the two primary challenges that need to be addressed. This paper presents a multi-modal deep learning technique to address the above challenges. The proposed modal can use and process visual and textual features. Therefore, it has the ability to detect fake information from visual and textual data. We used EfficientNetB0 and a sentence transformer, respectively, for detecting counterfeit images and for textural learning. Feature embedding is performed at individual channels, whilst fusion is done at the last classification layer. The late fusion is applied intentionally to mitigate the noisy data that are generated by multi-modalities. Extensive experiments are conducted, and performance is evaluated against state-of-the-art methods. Three real-world benchmark datasets, such as MediaEval (Twitter), Weibo, and Fakeddit, are used for experimentation. Result reveals that the proposed modal outperformed the state-of-the-art methods and achieved an accuracy of 86.48%, 82.50%, and 88.80%, respectively, for MediaEval (Twitter), Weibo, and Fakeddit datasets.

In this paper, we propose an efficient and effective selective protection scheme to SVC that exploit the propagation of protection effect by protecting significant frames that can give the maximum visual quality degradation. We model SVC dependency coding structure as a directed acyclic graph which is characterized with an estimated visual quality value as the attribute at each node. The estimated visual quality is calculated by using our model based on the proportions of intra- and inter-predicted MBs, amounts of residual, and estimated visual quality of reference frames. The proposed selective protection scheme traverses the graph to find optimal protection paths that can give maximum visual quality degradation. Experimental results show that the proposed selective protection scheme reduces the required number of frames to be protected by 46.02% compared to the whole protection scheme and 27.56% compared to the layered protection scheme.

Typography, as the median for communication, has expanded its roles according the attributes of the media where it Is used, and the change of media follwing the change of times is presenting new directions to the field of typography. The attempts of 20C experimental typography prioritize visual formativeness, free typography and language started to appear on printed matters and different kinds of prints put pep in magazines. Thus, experiments in the aspects of effective delivery of inpormation that letters have and aesthetic side of shapes of letter are continuing. Today with the appearance of multimedia, development of visual colture and rapid development of digital technology, the range of experimental typography has expanded even wider and therefore, different kinds of expressions became possible. As seen above, unlike the existing static printed media that carries linguistic information only, letters in the multimedia environment is shown in the movie titles, TV or web not only as a basic visual media such as type and image, but as a dynamic and complex factor that contains additional information of motion and sound factor. This study will attempt to find the historic context of focus of moment from the kinetic art and define the moving letters as kinetic typography. Therefore, this paper will have an understanding on kinetic typography's background, concept and characteristics following the change of communication environment in the multimedia era and tried to study the basic theories of kinetic typography and the information delivery and imagery function of letters. Also, this paper attempted to carry out a study on whether kinetic typography is delivering information smoothly from the aspect of communication through the image role as delivering information by studying major works of artists who have influenced kinetic typography. Based on this study, I would like to suggest new direction for effective delivery of information and value of use.

This study investigated Seoul's image as a tourism destination that Chinese tourists perceived, taking advantage of Chinese Social Media "Renren". The study used visual method (V-method) to collect images and analyzed them in terms of convergent disciplinary approach. It searched Chinese word, "首爾", in Renren social network. 526 Seoul's photos were collected from 129 users' mini-homepage. Destination planners and marketers should understand how the Chinese tourists perceive the Seoul's image and recognize the contribution factors to representations of the city. It is recommended that more cultural experience should be offered to Chinese tourists.
