The development of digital image technology has realized high definition throughout the image industry including film and broadcasting. Such high definition images are used in various media and forms through convergence with innovative displays. The analog image production mode is combined with image content production using digital technology. The purpose of this research is to present a method to reconstitute high definition multiplanar images on the wider and bigger screen by applying the Cinerama system, one of the analog image systems in the past, to digital technology.

In this paper, we are propose a method to estimate the 2-D mesh from structured light image for reconstruction of 3-D face image. To acquire the structured light image, we are project structured light on the face using the projector. we are extract the projected cross points from the acquire image. The 2-D mesh image is extracted from the position and angle of cross points. In the extraction processing, the error was fixed to extract the correct 2-D mesh.

This paper describes a new image watermarking scheme invariant to rotation, scaling and translation (RST) attacks. For obtaining the invariance properties we propose to present an image of watermark by wedges and rings to convert its rotation to shift and then utilize the shift invariance property of the Direct Fourier Transform (DFT). But in contrast to conversional schemes based on the Fourier-Mellin transform (FMT), we do not use a log-polar mapping (LPM). As a result, our scheme preserves high quality of original image since it is not underwent to LPM For withstanding against JPEG compression, noise addition and low-pass (LP) filtering attacks a low frequency watermark is embedded into middle frequencies of the original image. Experiments with various attacks show the robustness of the proposed scheme.

The attribute of cartoon and comics has been known the combination of image and text. It is improved the we find the shape of comics at the first comics on the newspaper. But we can read the comic without word. These works don't give the difficult to read and it may transfer to readers by the image of figure on comics. Therefore how can the image reach the readers by the communication. This study is the research of the visual image communication and the attribute of wordless comics.

The image communication system based on power line communication(PLC) that manages the status of workers in deteriorated. work environments such as high temperature and pressures as realtime is designed and implemented in this paper. The major design considerations for system design are such that the adaptation of simple architecture, simplicity of installation and movement, tolerances about high temperature and pressures, transmission of high quality image under various noise environments.

This paper proposes a new algorithm that generates a panorama image for reconstruction of image-based virtual environment. Proposed algorithm can generate panorama image from input images using the projective transform based on the feature model and a fully immersive image-based virtual environment according to the user's view point by the sphere mapping. Especially, proposed algorithm supports robust methods of camera rotation and is applied to various images to estimate ist performance.

In this paper, an accelerated generation algorithm to effectively generate an elemental image array in computational integral imaging system is proposed. In the proposed method, the depth information of 3D object is extracted from the images picked up by a stereo camera or depth camera. Then, the elemental image array can be generated by using the proposed accelerated generation algorithm with the depth information of 3D object. The resultant 3D image generated by the proposed accelerated generation algorithm was compared with that the conventional direct algorithm for verifying the efficiency of the proposed method. From the experimental results, the accuracy of elemental image generated by the proposed method could be confirmed.

In this paper, we propose a synthesis method of elemental images from Kinect images for 3D integral imaging display. Since RGB images and depth image obtained from Kinect are not able to display 3D images in integral imaging system, we need transform the elemental images in integral imaging display. To do so, we synthesize the elemental images based on the geometric optics mapping from the depth plane images obtained from RGB image and depth image. To show the usefulness of the proposed system, we carry out the preliminary experiments using the two person object and present the experimental results.

The personal image information compiled through closed-circuit television (CCTV) will be open to the internet with the technology such as Long-Tail, Mash-Up, Collective Intelligence, Tagging, Open Application Programming Interface (Open-API), Syndication, Podcasting and Asynchronous JavaScript and XML (AJAX). The movie User Created Contents (UCC) connected to the internet with the skill of web 2.0 has the effects of abuse and threat without precedent. The purpose of this research is to develop the institutional and technological method to reduce these effects. As a result of this research, in terms of technology this paper suggests Privacy Zone Masking, IP Filtering, Intrusion-detection System (IDS), Secure Sockets Layer (SSL), public key infrastructure (PKI), Hash and PDF Socket. While in terms of management this paper suggests Privacy Commons and Privacy Zone. Based on CCTV-UCC linked to the above network, the research regarding personal image information security is expected to aid in realizing insight and practical personal image information as a specific device in the following research.

Korean popular cultural content, "Hallyu", is prevalent in China, and those have changed some life styles of the Chinese people, who are crazy with it. Korean popular cultural content is more than a cultural phenomenon, it has enhanced the national image of the country and the tourism department, especially those popular products which are closely related to our daily life. From this point of views, the current study is to identify the relationship between Korean popular cultural contents, Korean image, and visiting intention to Korea. The questionnaire takes a volunteering method, and analyzed the general characteristics through SPSS21.0. Factor analysis and reliability analysis are provided in order to test the reliability and validity. As the result of the study, Korean popular cultural contents can enhance economic and culture image of Korea, and those are the main factor for the potential customers from China to visit Korea. This study can provide information for maintaining popular cultural contents and gives an implication for enhancing the Korean tourism policy.
