City image improvement is very important, particularly in city tourism development because tourism depends on image. Some cities have made efforts to develop a positive city image with local festivals. The purpose of this study was to assess the tourists' satisfaction of local festivals. First, the city image was focused on three factors; city satisfaction, experience and convenience. Second, the city image was influenced significantly by city satisfaction and direct or indirect experience. These results show that effective strategies are needed for the successful IT implementation in local festivals. The use of mobile applications and GIS-based sensors provide local festival information for tourists who receive information, Finally, a well made city image combines city identity and originality, which will attract many tourists and visitors.

This study intended to examine the nature of image which uses the network as the medium in the context of 'post-internet art' and categorize and analyze the cases of applications within art images. In the post-internet art which embraces the background of Web 2.0 and extended digital and network environment, image is transformed and re-mediated into various formats beyond fixed forms. Hito Steyerl defined the image, copied, downloaded, and reedited digitally in low quality as 'poor image.' Young artists, the digital native generation, capture and re-contextualize the changed network environment and depict it in various images. In this context, the application of image in post-internet art can be categorized and analyzed into the 'Image Collected as Material' produced by collecting and recomposing images found in social media, operating system, and website, 'Image Processed through Work' which is newly processed and re-contextualized by using editing programs, and 'Combined Digital-Reality Image' which represents the section of the digital society as the film and image that combine virtuality and reality.

The environment of images in VR-based animation is constructed to generate and promote interactivity between the images and the viewer without any physical space like a screen, or a monitor. In this process, the images and the viewer are combined as a complex through the media technology, that is, an interface. And it is far more in the case of the animation consisted of the bio-feedback interface closely connecting with the body of viewer. As a result, the viewer experiences a permeable interaction between ego and images world, namely virtual reality. That is different from the way of seeing and interpreting the images from a distance. So it needs to analyse the perception of viewer in the world of virtual images. This paper examines the complex phenomena of both the VR-based animation and the viewer mediated by the interface in light of Media Aesthetics. Media Aesthetics is effective in analysing the phenomena of VR-based animation, for it is concerned with the perception of viewer mediated by the media technology. The perception in VR-based animation is a full-body immersion, or embodied immersion, and it is different from the contemplative immersion in that it is remediated continuously by the technological apparatus. The viewer as an immersant, especially with a bio-feedback interface, can immediately touch and control the images in VR-based animation. Such an immersion, therefore, is new every single moment. And the world of VR-based animation is ultimately constructed through the viewer's full-body, or embodied immersion crossing between the virtual and the real. So the animation is not interpreted, but embodied. And the meaning of it is constructed and reconstructed by the viewer's embodied immersion as an immersant. Here, a new frame of animation more oriented to the viewer's participation as an full-body immersant can be created.

Techniques for generating new sample data from higher dimensional data such as images have been utilized variously for speech synthesis, image conversion and image restoration. This paper adopts Progressive Growing of Generative Adversarial Networks(PG-GANs) as an implementation model to generate high-resolution images and to enhance variation of the generated images, and applied it to fashion image data. PG-GANs allows the generator and discriminator to progressively learn at the same time, continuously adding new layers from low-resolution images to result high-resolution images. We also proposed a Mini-batch Discrimination method to increase the diversity of generated data, and proposed a Sliced Wasserstein Distance(SWD) evaluation method instead of the existing MS-SSIM to evaluate the GAN model.

We evaluate the face detection and recognition of depth image that is obtained by infrared range sensor. and Face recognition was usually focused on accuracy aspect but it is not enough to evaluate the performance in testing for real world application. In this paper, we evaluate the overall performance like accuracy, training, test speed and memory use for the well known face recognition algorithm like PCA, LDA, ICA and SVM. This experiment evaluate the good results of depth and colored depth image compatible with the colored image although the file size of depth and colored depth image is 30%~40% less than the colored image. Whereas, LDA got the good accuracy performance next to the SVM and also shows the good performance in speed and the amount of memory.

This paper focuses to find out and analyse the influence of evaluation and image of government technology development programs on the outcome. A comprehensive survey of domestic technology-intensive industry was carried out. Through the results of this survey, we can understand and find out the impotance of the image and evaluation of the programs taken by the firms. We could find out, however, that the output of the technology development of the enerprises is one thing and outcome in the level of society is another, especially as for the influences of evaluation on the performances. In this regard, we could draw several policy implications as well as discussions.

The study examines the interactive effect of spoken words and imagery not synchronized in audio/image surrogates for video gisting. To do that, we conducted an experiment with 64 participants, under the assumption that participants would better understand the content of videos when viewing audio/image surrogates rather than audio or image surrogates. The results of the experiment showed that overall audio/image surrogates were better than audio or image surrogates for video gisting, although the unsynchronized multimedia surrogates made it difficult for some participants to pay attention to both audio and image when the content they present is very different.

인터넷과 통신기술의 급격한 발전으로 인한 디지털 컨텐츠의 저자 동의 없는 복사 배포의 증가는 저작권 침해 및 불법 복제 및 배포, 위조 등의 문제를 발생시켰다. 이러한 저작권 문제를 해결하기 위한 사후적 방법으로 디지털 워터마크 기술이 개발되었다. 본 논문은 이산 웨이블릿 변환의 트리플린 특징을 이용한 바코드 이미지 워터마크 알고리즘을 제안하였다. 바코드 이미지 워터마크에 일정한 패턴을 이용하여 여러 공격에 강인성을 갖게 하였다. 또한 워터마크 추출시 상관도를 구하지 않아도 시각적으로 워터마크의 삽입 여부를 확인 할 수 있으며, 낮은 상관도에서도 워터마크를 시각적으로 확인 할 수 있는 장점을 갖는다.
