The quantity of image frames, the widths of transparent slits, and the black bars on the scanline are the three basic elements of scanimation. Besides, the size of scanimation, the color and contrast of scanimation, and the brightness of scanline, etc, can also influence the optical illusion of scanimation. Based on the recent principle of production of 2D scanimation, and through asking questions, and making corresponding experiment, this research finally gets to the conclusion. Based on the principle of production of 3D scanimation, and through various basic testing, this paper aims to verify how to bring out the best visual effects (optical illusion) of animated illusion scanimation in publications by using the 3D animation in the publications. And the future goal is to study and flexibly use Z-axis space in the scanimation.

2차원 이미지는 오래전부터 발전되어온 훌륭한 표현 방법 중 한가지 이다. 하지만 단순한 2차원 이미지만을 가지고 보정과 편집을 통해 다양한 효과를 표현하는데 있어 여러 가지 한계가 있다. 본 논문에서는 2차원의 평면 이미지인 나비와 춘란의 이미지를 사용하여 나비의 날개짓과 춘란의 생장을 표현함으로써 단순한 2차원 평면 이미지를 사용하여 3차원 공간상에서 움직임과 동적인 느낌을 강조한 3차원 영상 제작기법을 구현하고자 한다. 이러한 영상제작기법은 동적인 효과를 가진 고품질의 영상을 쉽게 제작할 수 있기 때문에 개인 뿐만 아니라 전문 방송과 영상 매체에 효율적으로 적용할 수 있다는 장점을 가지고 있다.

본 논문에서는 훼손되어 식별할 수 없는 탑 이미지를 비롯해 낮은 해상도의 탑 이미지를 개선하기 위해 우리는 탑 이미지의 화질 개선을 인공지능을 이용하여 빠르게 개선을 해 보고자 한다. 최근에 Generative Adversarial Networks(GANS) 알고리즘에서 SrGAN 알고리즘이 나오면서 이미지 생성, 이미지 복원, 해상도 변화 분야가 지속해서 발전하고 있다. 이에 본 연구에서는 다양한 GAN 알고리즘을 화질 개선에 적용해 보았다. 탑 이미지에 GAN 알고리즘 중 SrGan을 적용하였으며 실험한 결과 Srgan 알고리즘은 학습이 진행되었으며, 낮은 해상도의 탑 이미지가 높은 해상도, 초고해상도 이미지가 생성되는 것을 확인했다.

Technologies of the 4th industrial revolution have been unknowingly seeping into our lives. Many IoT based home security systems are using the convolutional neural network(CNN) as good biometrics to recognize a face and protect home and family from intruders since CNN has demonstrated its excellent ability in image recognition. In this paper, three layouts of CNN for 2D and 2.5D image of small dataset with various input image size and filter size are explored. The simulation results show that the layout of CNN with 50*50 input size of 2.5D image, 2 convolution and max pooling layer, and 3*3 filter size for small dataset of 2.5D image is optimal for a home security system with recognition accuracy of 0.966. In addition, the longest CPU time consumption for one input image is 0.057S. The proposed layout of CNN for a face recognition is suitable to control the actuators in the home security system because a home security system requires good face recognition and short recognition time.

This paper is to study and implement 3D Virtual Face Aesthetic Surgery System which provides more satisfaction by comparing the before-and-after plastic face surgery using 3D face model. For this study, we implemented 3D Face Model Generating System which resembles 2D image of the user based on 3D Korean standard face model and user's 2D pictures. The proposed 3D Virtual Face Aesthetic Surgery System in this paper consists of 3D Face Model Generating System, 3D Skin Texture Mapping System, and Detailed Adjustment System for reflecting the detailed description of face. The proposed system provides more satisfaction to the medical uses and stability in the surgery in compare with other existing systems.

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.

In 3D animation rendering process, Although we can render the output as a movie file format, most productions use image sequences in their rendering pipelines. This Image Sequence rendering process is extremely important step in final compositing in movie industries. Although there are various type of making image rendering processes, TGA format Is one of most widely used bitmap file formats using in industries. People may ask TGA format is most suitable for in any case. As we know 3D softwares have their own image formats. so we need to testify on this. In this paper, we are going to focus on Alias' 3D package software called MAYA which we will analyze of compressing image sequence, Image quality, supporting Alpha channels in compositing, and Z-depth information. The purpose of this paper is providing to 3D Pipeline as a guideline about effective image sequence format.

대부분의 현존하는 인터넷쇼핑몰은 평면적인 2차원으로 운영되고 있으나 최근 가상현실(Virtual Reality)을 이용하여 웹에 적용시키는 기법들이 속속 선보이게 되었다. 현재의 3D기술은 크게 사진 이미지를 기반으로 방식과 폴리곤(Polygon)을 기반으로 하는 3차원 모델링 기술의 두 가지로 구분할 수 있다. 이들 기법은 각각 장단점이 있으며 이들을 이용하는 사이트들 역시 이용하는 기법에 따라 다소간의 문제점들을 노출하고 있다. 본 논문에서는 사진 이미지 기법을 이용하는 부분은 현재 브라우저에서 기본적으로 지원하는 자바를 이용하여 구현했으며, 네비게이션이나 물체의 3차원 렌더링 구현 등은 java3d를 이용하여 상호간의 상반되는 단점들을 최소화하였다. 사용자는 Java3d로 구현된 3차원 쇼핑몰 내에서 원하는 물체를 클릭하여 위에서 언급한 2가지 방식으로 살펴볼 수 있다. 사진 이미지 형식으로 구현된 제품은 이미 실세계의 전자상거래 쇼핑몰에서 구현되었으며, 3차원 모델링으로 구현된 제품은 VRML97, OBJ, 3DS 등의 화일 포맷을 Java3d 로더를 이용하여 다양한 방식으로 구현하여 기존 방식과의 차별화 및 성능 향상을 꾀하였다.

The random and heterogeneous pore structure is a significant factor that dominates physical and mechanical behaviors of soils such as fluid flow and geomechanical responses driven by loading. The characterization method using non-destructive testing such as micro X-ray CT technique which has a high resolution with micrometer unit allows to observe internal structure of soils. However, the application has been limited to qualitatively observe 2D and 3D CT images and to obtain the void ratio at macro-scale although the CT images contain enormous information of materials of interests. In this study, we constructed the 3D particle and pore structures based on sequentially taken 2D images of glass beads and quantitatively defined complex pore structure with void cell and void channel. This approach was enabled by implementing image processing techniques that include coordinate transformation, binarization, Delaunay Triangulation, and Euclidean Distance Transform. It was confirmed that the suggested algorithm allows to quantitatively evaluate the distribution of void cells and their connectivity of heterogeneous pore structures for glass beads.
