To create gesture from a new text input is an important problem in computer games and virtual reality. Recently, there is increasing interest in gesture stylization to imitate the gestures of celebrities, such as announcer. However, no attempt has been made so far to stylize a gestures using emotion such as happiness and sadness. Previous researches have not focused on real-time algorithm. In this paper, we present a system to automatically make gesture animation from SMS text and stylize the gesture from emotion. A key feature of this system is a real-time algorithm to combine gestures with emotion. Because the system's platform is a mobile phone, we distribute much works on the server and client. Therefore, the system guarantees real-time performance of 15 or more frames per second. At first, we extract words to express feelings and its corresponding gesture from Disney video and model the gesture statistically. And then, we introduce the theory of Laban Movement Analysis to combine gesture and emotion. In order to evaluate our system, we analyze user survey responses.

To access PDF documents on an electronic book, PDF documents need to be converted into EPUB which is a standard format of the electronic book. When converting a PDF document into EPUB format, we need to convert color representations from CMYK into RGB representation. It is possible to give a visual effect and a user interaction using a video and JavaScript supported by EPUB format. The schemes for converting from PDF to EPUB are studied in this paper. (1) The first study is to carry out not to lose the color conversion effect using an ICC profile. (2) The second one is a layout configuration in the conversion process. (3) The third one is to highlight a specific content such as quiz platform to provide interactive visual effect for electronic book readers. Finally, in this paper we will show the usability of EPUB based eBook converting scheme through user study.

Recently, the emotional design has become one of the central issues. The interest to Calligraphy also has increased. This study is to examine the effect of calligraphic TV title to viewers through questionnaires. As a result of the questionnaire analysis, calligraphic title makes a favorable impression on viewers. On the other hand, viewers have an antipathy to a drama program with a calligraphic title. The appropriate use of calligraphic title is requested. The viewers prefer that CM Super TV drama title is located to the right side in TV screen. They also prefer the animated moving title to colored background title. This study contributes to the further research about the correlation between TV commercial zap-rate and calligraphic title.

In this paper, we propose an Active Shape Model (ASM) and Lucas-Kanade (LK) optical flow-based feature extraction and analysis method for analyzing the emotional features from facial images. Considering the facial emotion feature regions are described by Facial Action Coding System, we construct the feature-related shape models based on the combination of landmarks and extract the LK optical flow vectors at each landmarks based on the centre pixels of motion vector window. The facial emotion features are modelled by the combination of the optical flow vectors and the emotional states of facial image can be estimated by the probabilistic estimation technique, such as Bayesian classifier. Also, we extract the optimal emotional features that are considered the high correlation between feature points and emotional states by using common spatial pattern (CSP) analysis in order to improvise the operational efficiency and accuracy of emotional feature extraction process.

This study is a model of research for the developing 3D character contents about facial expression as a sort of non-linguistic signs, focusing on an expression of emotion factors of a person. It contributes a framework for symbolic analysis about Human's emotions along with a general review of expression. The human face is the most complex and versatile of all species. For humans, the face is a ich and versatile instrument serving many different functions. It serves as a window to display one's own motivational state. This makes one's behavior more predictable and understandable to others and improves communication. The face can be used to supplement verbal communication. A prompt facial display can reveal the speaker's attitude about the information being conveyed. Alternatively, the face can be used to complement verbal communication, such as lifting of eyebrows to lend additional emphasis to stressed word. The facial expression plays a important role under the digital visual context. This study will present a frame of facial expression categories for effective manufacture of cartoon and animation that appeal to the visual emotion of the human.

This study aims to examine the present (Western) modern dance by analyzing the works of three choreographers who are currently at the forefront of the dance scene to identify and understand the current choreographic trend. The three selected choreographers for this study are Justin Peck (USA), Sidi Larbi Cherkaoui (Belgium) and Zach Morris (USA). These choreographers were chosen on the basis of their significant identity within the current dance scene. For analysis, one noteworthy works of each choreographer were selected for video analysis. The result of the analysis illustrates that in the current era of promoting technology convergence in the performing arts industry, the three choreographers approach convergence differently by integrating dance and other mediums in their choreography. Peck converges between ballet and the ordinary, Cherkaoui converges between dance and other cultures and Morris converges between dance and venue.

As with all narrative forms based on media, the narrative method of TV human documentary is closely related to the change of broadcasting environment. In 2017, the world's first terrestrial UHD broadcast was launched in Korea, and in September of that year, KBS broadcasted the UHD special documentary series. , made of UHD capable of ultra-high definition video and immersive audio, showed a narrative approach completely different from the existing TV human documentary. Instead of all-out narration, which was considered an essential element in the TV human documentary, it used the modest first-person narration of the characters, while actively using drones capable of various compositions to express the psychology of the characters in detail and enable viewers' immersion. In addition, the Montage editing technique, an editing method that has not been attempted in TV human documentaries, utilizes the narrative development method of 'showing' as a video without 'explaining' with narration. After , many similar narrative documentaries are broadcast, and the flow and direction of TV human documentaries are changing under UHD broadcasting environment.

With increasing user applicability of geospatial data, user demand for manifold and accurate information has increased. The usefulness of these services derives from their combination of the advantages of as-built geospatial data in making new content. There is a spatial inconsistency and shape disagreement in fusing heterogeneous data. Conflation, defined as the combining of information from diverse sources so as to reconcile spatial inconsistencies and shape disagreement, is possible solution to the problem. In this research, we developed the technique for removing shape disagreement between aerial image and road map removed spatial inconsistency in advanced research. The process includes four processes: producing of a road candidate image, extraction of vertices, and generation of a graph by connecting the vertices. We could remove the shape disagreement using the extracted road that was derived from finding the road possible path.
