The Avengers film produced by Marvel Comics shows visual effects that were impossible to produce in the past. Companies that produce film special effects were initially equipped with large personnel and equipment, but technology is gradually evolving to be feasible for smaller companies that do not have high-priced equipment and a large workforce. The development of hardware and software is becoming increasingly available to the general public as well as to experts. Equipment and software which were difficult for individuals to purchase before quickly popularized high-performance computers as the game industry developed. The development of the cloud has been the driving force behind software costs. As augmented reality (AR) performance of mobile devices improves, advanced technologies such as motion tracking and face recognition technology are no longer implemented by expensive equipment. Under these circumstances, after implementing mobile-based facial capture technology in animation projects, we have identified the pros and the cons and suggest better solutions to improve the problem.

It is no longer an issue that there is a big audience for Korean movies. More than 120 Korean movies are made each year. Many win prizes at film festivals around the world. But the number of animation movies made in Korea is decreasing even though the government tried to revitalize the animation industry in the mid-1990s. The problem is that all Korean animation movies were box-office failures, even though "Mary's Story" and "Oseam" were awarded prizes in world-famous animation festivals. Korean animation movies also face hurdles because of different cultural tastes of Korean audiences and problems with distribution. But there is a tremendous amount of potential and possibilities for Korean animation movies to be box-office blockbusters and artistic successes. There are ways to develop and revitalize the Korean animation industry and make it of the most important businesses and cultural influences in Korean society.

This paper describes methodology which enables user in order to generate facial expression animation of caricature which applies a facial motion data in the vector based caricature. This method which sees was embodied with the plug-in of illustrator. And It is equipping the user interface of separate way. The data which is used in experiment attaches 28 small-sized markers in important muscular part of the actor face and captured the multiple many expression which is various with Facial Tracker. The caricature was produced in the bezier curve form which has a respectively control point from location of the important marker which attaches in the face of the actor when motion capturing to connection with motion data and the region which is identical. The facial motion data compares in the caricature and the spatial scale went through a motion calibration process too because of size. And with the user letting the control did possibly at any time. In order connecting the caricature and the markers also, we did possibly with the click the corresponding region of the caricature, after the user selects each name of the face region from the menu. Finally, this paper used a user interface of illustrator and in order for the caricature facial expression animation generation which applies a facial motion data in the vector based caricature to be possible.

Recently, various computing technologies such as artificial intelligence, big data, and IoT are developing. In particular, artificial intelligence-based deepfake technology is being used in various fields such as the content and medical industry. Deepfake technology is a combination of deep learning and fake, and is a technology that synthesizes a person's face or body through deep learning, which is a core technology of AI, to imitate accents and voices. This paper uses deepfake technology to study the creation of virtual characters through the synthesis of animation models and real person photos. Through this, it is possible to minimize various cost losses occurring in the animation production process and support writers' work. In addition, as deepfake open source spreads on the Internet, many problems emerge, and crimes that abuse deepfake technology are prevalent. Through this study, we propose a new perspective on this technology by applying the deepfake technology to children's material rather than adult material.

In this paper, we propose a new method which generates the trajectory of the mouth shape for the characters by the user inputs. It is based on the character at a basis syllable and can be suitable to the mouth shape generation. In this paper, we understand the principle of the Korean language creation and find the similarity for the form of the mouth shape and select it as a basic syllable. We also consider the articulation of this phoneme for it and create a new mouth shape trajectory and apply at face of an 3D avatar.

Yeon Sang-Ho's Animation occupies an exceptional place in Korean Animation, being categorized as the kind of realism representing the pitiable actuality rather than the liberal and creative imagination. His animation appreciated as 'stories much more real than the reality' mainly depicts the world of 'the others' who resides on the periphery of the society in a rough and straightforward way. Yeon Sang-Ho's Animation represents the emotions and desire of characters as well as the heartless real world refusing the fantasy, through which it reflects the portraits of people living in post-capitalistic era seen from the microscopic view. This article investigates the textual characteristics, defining his animation as the Brutal history of 'The Others'. Two conditions which constitute the actual world in his works are the absurd social system and the characters who are afflicted with the trauma, belonging to the lower classes. Therefore, the landscape of real life which contains vicious victim, corrupted monster and being as 'homo sacer' looks like a painting of hell. Yeon Sang-Ho's Animation summons the shadow of ourselves which has been negated or neglected through the figure of 'the others' produced in post-capitalistic era and exposes our bare face and the uncomfortable truth by displaying the affected area of out society plainly. Furthermore, his works demonstrate the possibility of Korean animation as a representational language of facing the reality and searching for the truth.

The researches of image recognition have been processed traditionally. Especially, face recognition technology has been received attractions with advance and applied to various areas according as camera sensor embedded into many devices such as smart phone. In this study, we design and develop a feature vector generation technique of face for making animation caricatures using methods for face detection which are previous stage of face recognition. At first, we detect both face region and detailed eye region of component element by Viola&Johns's realtime detection method which are called as ROI(Region Of Interest). And then, we generate feature vectors of eye region by utilizing factors as opposed to the periphery and by using appearance information of eye. At this point, we focus on the embedded information in many color spaces to overcome the problems which can be occurred by using one color space. We propose a feature vector generation method using information from many color spaces. Finally, we experiment the test of feature vector generation by the proposed method with enough quantity of sample picture data and evaluate the proposed method for factors of estimating performance such as error rate, accuracy and generation time.
