This study shows that there is an essential difference between colors of animation and live action film through the expressive colors of 2D animation as distinct from three dimension space. While live action film has an obvious object of representation, the image of 2D animation is a creature made by human without the process of mechanical representation. And this is revealed sharply in the expressive colors of 2D animation. Therefore the expressive colors of 2D animation are the important points in which the autonomous meaning of animation image is revealed.

This paper reports on the ACQA(Animated agent for Conversational Question Answering) project conducted at LIMSI. The aim is to design an expressive animated conversational agent(ACA) for conducting research along two main lines: 1/ perceptual experiments(eg perception of expressivity and 3D movements in both audio and visual channels): 2/ design of human-computer interfaces requiring head models at different resolutions and the integration of the talking head in virtual scenes. The target application of this expressive ACA is a real-time question and answer speech based system developed at LIMSI(RITEL). The architecture of the system is based on distributed modules exchanging messages through a network protocol. The main components of the system are: RITEL a question and answer system searching raw text, which is able to produce a text(the answer) and attitudinal information; this attitudinal information is then processed for delivering expressive tags; the text is converted into phoneme, viseme, and prosodic descriptions. Audio speech is generated by the LIMSI selection-concatenation text-to-speech engine. Visual speech is using MPEG4 keypoint-based animation, and is rendered in real-time by Virtual Choreographer (VirChor), a GPU-based 3D engine. Finally, visual and audio speech is played in a 3D audio and visual scene. The project also puts a lot of effort for realistic visual and audio 3D rendering. A new model of phoneme-dependant human radiation patterns is included in the speech synthesis system, so that the ACA can move in the virtual scene with realistic 3D visual and audio rendering.

This paper examines the ink on paper technique that is being used in the animation works by the Canadian filmmaker Michēle Cournoyner from the National Film Board of Canada. It also discusses how in her animated film "Soif"(2013) this technique has been applied to compose the narrative significance and symbols through the use of metamorphosis as a form of artistic expression. Cournoyner had used the ink of paper technique as a means to abandon realistic representations of movement, and in "Soif" through expressive use of metamorphosis, portrayed changes of images in character and object not through chronological order of narrative flow, but through the body of the female character, which had been represented by the improvisation of the ink on paper technique in order to express the surrealistic and unconscious state of mind in animation. Also, the use of Surrealist automatism had been incorporated to evoke the film towards a form of abstract and metaphysical expression, which in terms of expression and technique connects with the character in the animation to give emphasis to its relevancy with the subject matter of the work.

Creating stylistic facial animation is one of the most important problems in character animation. Traditionally facial animation is created manually by animators of captured using motion capture systems. But this process is very difficult and labor-intensive. In this work, we present an intuitive, easy-to-use, sketch-based user interface system that facilitates the process of creating facial animation and key-frame interpolation method using facial capture data. The user of our system is allowed to create expressive speech facial animation easily and rapidly.

Technology in the animation industry has evolved significantly over the past decade. The tools to create animation are becoming more intuitive to use. Animators now spend more time on the artistic quality of their work than wasting time figuring out how to use the software that they rely on. However, one particular tool that is still unintuitive for animators is the motion graph editor. A motion graph editor is a tool to manipulate the interpolation of the movements generated by the software. Although the motion graph editor contains a lot of options to control the outcome of the animation, the emotional rhythm of the movements desired by the animator still depends on the animator's skill, which requires a very steep learning curve. More often than not, animators had to resort to trial and error methods to achieve good results. This inevitably leads to slow productivity, susceptible to mistakes, and waste of resources. This research will study the connection between the motion graph profile and the emotions they portray in movements. The findings will hopefully be able to provide animators reference materials to achieve the emotional animation they need with less effort.

The aesthetics of Japanese animation have developed in earnest since Tezuka Osamu produced TV animation . This is because provided the aesthetic foundation of '3-comma animation' and 'limited animation techniques based on 8 frames per second. In fact, Miyazaki Hayao and Takahata Isao of Ghibli studio have expanded the influence of the Japanese animation industry to the world through the production of feature animation based on 3-comma animation. Inoue Toshiyuki, who participated as an animator in many works representing the Japanese animation industry, also said that the essential feature of Japanese animation aesthetics is 3 comma animation that shows the impressive movement of the character concisely. As such, 3-comma animation technique is the main aesthetic background that has led to the industrial development of Japanese animation.

The purpose of this research is to study a case of allegory and experimental presentation technique in Film by Zbigniew Rybczynski. It is to analyse this study is to inquire into the fact that experimental animation carries diverse interpretation of comtemporary art and the purpose of this study is to identify certain style through the interpretation of allegory focused on film Tango which has expanded the field of experimental animation with the unique form of the film structure and technique. Therefore, in this research, I would highlight the characteristic of allegory in Film by Zbigniew Rybczynski and research the experimental presentation technique that appears in experimental animation focused on "fragmentation" which are the expressive style of allegory.

The talking head (TH) indicates an utterance face animation generated based on text and voice input. In this paper, we propose the generation method of TH with facial expression and intonation by speech input only. The problem of generating TH from speech can be regarded as a regression problem from the acoustic feature sequence to the facial code sequence which is a low dimensional vector representation that can efficiently encode and decode a face image. This regression was modeled by bidirectional RNN and trained by using SAVEE database of the front utterance face animation database as training data. The proposed method is able to generate TH with facial expression and intonation TH by using acoustic features such as MFCC, dynamic elements of MFCC, energy, and F0. According to the experiments, the configuration of the BLSTM layer of the first and second layers of bidirectional RNN was able to predict the face code best. For the evaluation, a questionnaire survey was conducted for 62 persons who watched TH animations, generated by the proposed method and the previous method. As a result, 77% of the respondents answered that the proposed method generated TH, which matches well with the speech.

Cultural policy, a part of ideological policy has affected remarkable changes in movie and animation. Korean animation was called cartoon movie and popular only among children, but works dealing with anti-communism ideology have been introduced in Korea since before/after 1970s. Animation focusing on ideology is not unique in Korea, but division of two Koreas after Korean War made great influence on social, cultural and educational aspects of the nation. Moreover, modification in movie-related laws and regulations made in 1960s - 1970s affected movie and animation significantly and is a means of strengthening anti-communism. In particular, Director Cheong-gi Kim's released in 1978 is meaningful in that it is the first long piece of animation movie. In this study, I clarify anticommunistic ideology reflected on the anticommunistic animations and the imageable expression of ideology reflected on . Most of all, I emphasize on clarifying how the cultural policies and social & cultural background influence on the advent of anticommunistic animation in 1960${\sim}$1970. Also, to communicate anticommunistic ideology reflected on produced under the social & cultural background, I clarify the expressive characteristic which the image of animation has.

I try to extract typological factors from the historically relevant works of animation, for that we can refer 'style.' creator's individuality, general tendencies and restraints of his time, the national properties work on them. It is the individual aspect that excels in the works of Jiri Trnka, Tim Burton, Yuri Norstein, so they stand out not only in their own specific sensibility, vision but also in the elucidation of themes and the technology of dealing medium. On the other hand the Walt Disney's animation has so distinctive characteristics that we could identify them. Disney's so-called classical model accomplished a typically American animation form as full of expressive visual language, over reaction, full animation describing detail action. We could tell, Miyajaki Hayao's Gibri Studio represents Japanese animation, which works on traditional motives of Japan and expresses unique humanity.
