This paper describes a character retrieval system for TV programs and a set of novel algorithms for detecting and recognizing faces for the system. Our character retrieval system consists of two main components: Face Register and Face Recognizer. The Face Register detects faces in video frames and then guides users to register the detected faces of interest into the database. The Face Recognizer displays the appearance interval of each character on the timeline interface and the list of scenes with the names of characters that appear on each scene. These two components also provide a function to modify incorrect results. which is helpful to provide accurate character retrieval services. In the proposed face detection and recognition algorithms. we reduce the computation time without sacrificing the recognition accuracy by using the DCT/LDA method for face feature extraction. We also develop the character retrieval system in the form of plug-in. By plugging in our system to a cataloguing system. the metadata about the characters in a video can be automatically generated. Through this system, we can easily realize sophisticated on-demand video services which provide the search of scenes of a specific TV star.

In this paper, we introduced a system that extracts metadata by recognizing characters and objects in media using deep learning technology. In the field of broadcasting, multimedia contents such as video, audio, image, and text have been converted to digital contents for a long time, but the unconverted resources still remain vast. Building media archives requires a lot of manual work, which is time consuming and costly. Therefore, by implementing a deep learning-based metadata generation system, it is possible to save time and cost in constructing media archives. The whole system consists of four elements: training data generation module, object recognition module, character recognition module, and API server. The deep learning network module and the face recognition module are implemented to recognize characters and objects from the media and describe them as metadata. The training data generation module was designed separately to facilitate the construction of data for training neural network, and the functions of face recognition and object recognition were configured as an API server. We trained the two neural-networks using 1500 persons and 80 kinds of object data and confirmed that the accuracy is 98% in the character test data and 42% in the object data.

Childhood verbal communication impacts children's language skills and has a positive effect as partners use more vocabulary. But reduction in family time, caused by lowered age for private education and so on, has reduced the chance for children to speak with partners who have a proficient language skill. This vacancy was naturally occupied by the media, which has become one of the cornerstones of the growth of kids' contents. Kids contents are making various attempts to expand the breadth of services. But most contents still focus on unilateral visual information delivery yet, so there is a limit to satisfy the vacancy of conversation partners. Therefore this paper suggests an ECA(Embodied conversational agent) to induce children's spoken conversation using a virtual character frequently used in kids contents. This system is implemented by the voice bot and agent model produced using an IBM assistant and Unity. As a result of using ECA for 66 children of 5-9 years old, it showed meaningful results in terms of induction of verbal communication.

Domestic and international energy and eco-friendly companies take advantage of social media for image enhancement and product promotion. However, there were no in-depth empirical analysis to verify specific effectiveness of social media use in these sectors. The purpose of this study is to reveal the key factors that are considered to use social media effectively for energy and eco-friendly companies. For this purpose, we regarded the effectiveness of social media as Post Awareness and Word of Mouth. Characteristics of social media as a medium were measured separately, media richness and media genre, as independent variables of social media effectiveness. We investigated 413 posts in Facebook brand page of energy and eco-friendly companies and conducted a content analysis. As a result, post awareness of users was greater when post has richer media such as video. For media genre, word of mouth appeared to be greater when the posts provide information.

It is necessary to analyze the character that are a key element of the story in order to analyze the story. Current character analysis methods such as Character-net and RoleNet are not sufficient to classify the roles of supporting characters by only analyzing the results of the final accumulated stories. It is necessary to study the time series analysis method according to the story progress in order to analyze the role of supporting characters rather than the accumulated story analysis method. In this paper, we propose a method to classify helpers as a mentor and a best friend through 3-D visualization of Character-net and evaluate the accuracy of the method. WebGL is used to configure the interface for 3D visualization so that anyone can see the results on the web browser. It is also proposed that rules to distinguish mentors and best friends and evaluated their performance. The results of the evaluation of 10 characters selected for 7 films confirms that they are 90% accurate.

It is said that today is an era of total cord characterized by the transition from the industrial society to the knowledge based and information one. In this age of total cord, the most complex media production is the game industry. In the game industry, game character as one of the elements of game production is the most important because it contains visual elements created through interaction with a user. Initial creation of characters in the game industry is considered having the most value-adding element. Character creation in game production begins with basic drawings, like a diffusive property of the production elements, and proceeds to complicated 2D game character illustration and 3D game character production. In addition, only when driving forces for game development such as individuality and virtual reality are based on different mind cord from existing one, foundation for it will be firmly established. Therefore, it is clear that understanding of the Importance of character illustration and original drawings in the game production is essential to successfully produce more perfect 3D game characters.

The study looks a shape of hybrid character in animation and suggests extended discussion to develop the Korean creative characters and to repeat traditional culture that can reproduce in mass media. First, this study considers Jangseung and Dokkaebi that appear frequently in the Korean traditional culture, and prepares a way to try to develop the Korean hybrid characters. To do this, I analyze examples of hybrid characters direction in as-found animation characters, and grasp the meaning of it. Hybrid character is classified as a character produced by mix and combination of shape and a character produced by shape exaggeration. And I shed new light on characters and meanings of Jangseung and Dokkaebi remaining as cultural assets. Through this, the study wants to help handling measure about a problem of character that the Korean animation has. Therefore, this study looks characters of description about imaginary creatures expressed in existing animations, and wants to shed new light on the Korean Jangseung and Dokkaebi regarded as from an object of folk religion and custom, to an object that is possible to use in the Korean traditional character development.

In this research, I analyze cases of character packages in Japane, extract the concept of design that was loved by consumers and inmates and succeeded in marketing, and aim to establish the logic and principle. In addition, in the future, when introducing and utilizing the character package design in Korea, this research intends to make a guideline for the development of objective validity and empathic package design. After identifying the design concept and finding the principle by targeting package design of five character of Tohato which mixed various media and expanded sales, I want to find out the cause of success. Therefore, I have studied the theory and principles of enterprise and creative in product strategy through case analysis of character design concept and character package design. As a result, a design that leaving the functional side, having a story, making memories, and inducing a sense of closeness was as a successful case of renewal. In the package design, in some cases, package design execution is more important under the theoretical system according to consumer behavior analysis and Promotion of bold design concept of the design for the success of that concept, deviated from the existing principle.
