Reflecting times, Korean TV dramas have gone through massive changes. So have their main characters. This study is about their jobs, which have become more professional as well as diverse. It is observed that the male characters" jobs and job-related episodes take the center stage in the stories of dramas, rather than love stories of those characters. While main characters' jobs used to be part of the overall backdrop in the past, it has been the latest trend for a drama to begin building conflicts around and in the meticulously described work settings. This is opening up the possibility for new categories of genre dramas, as opposed to the typical Koran melodramas. For further success of this newly burgeoning trend, the sense of reality matters the most. Then, it requires elaborately built narratives, based upon a high level of expertise of playwrights in the relevant fields, and realistic proper image processing techniques.

Texture mapping is the process of covering 3D models with texture images in order to increase the visual realism of the models. For proper mapping the coordinates of texture images need to coincide with those of the 3D models. When projective images from the camera are used as texture images, the texture image coordinates are defined by a camera calibration method. The texture image coordinates are determined by the relation between the coordinate systems of the camera image and the 3D object. With the projective camera images, the distortion effect caused by the camera lenses should be compensated in order to get accurate texture coordinates. The distortion effect problem has been dealt with iterative methods, where the camera calibration coefficients are computed first without considering the distortion effect and then modified properly. The methods not only cause to change the position of the camera perspective line in the image plane, but also require more control points. In this paper, a new iterative method is suggested for reducing the error by fixing the principal points in the image plane. The method considers the image distortion effect independently and fixes the values of correction coefficients, with which the distortion coefficients can be computed with fewer control points. It is shown that the camera distortion effects are compensated with fewer numbers of control points than the previous methods and the projective texture mapping results in more realistic image.

In the full white pattern, white uniformity means the degree of uniform distribution of white color and luminance across the whole screen. Among the FPDs(Flat Panel Displays), the TFT-LCD has weak point of viewing angle. The viewing angle considering location and direction can cause different image quality of the TFT-LCD. Therefore, white uniformity of the TFT-LCD must consider viewing angle. Based on international standards, this study proposes an alternative that is realistic and ergonomic measurement of white uniformity of the TFT-LCD.

Recent work by Ravanbakhsh et al. (2017), Mathuriya et al. (2018) showed that convolutional neural networks (CNN) can be trained to predict cosmological parameters from the visual shape of the large scale structure, i.e. the filaments, clusters and voids of the cosmic density field. These preliminary works used the dark matter density field at redshift zero. We build upon these works by considering realistic mock galaxy catalogues that mimic true observations. We construct light-cones that span the redshift range appropriate for current and near future cosmological surveys such as LSST, EUCLID, WFIRST etc. In summary, we propose a novel multi-image input CNN to track the evolution in the morphology of large scale structures over cosmic time to constrain cosmology and the expansion history of the Universe.

Camouflage is evaluated by scientific principle in the fields of biology, military science, and art. It has a strong influence on contemporary fashion and means exposure with concealment. This study analyzed the visual characteristics of camouflage patterns in fashion design through documentaries and fashion photos. The fashion design results areas follow. The simple blending of a disruptive motif indicated an inaccurate repetition of a disruptive motif, the discontinuous or continuous connection of disruptive motif, the irregular repetition of a disruptive animal silhouette, the collage of a different disruptive motif, the craft of a disruptive motif and the intensive color match of a disruptive motif. It represented the maximization of complication, fantastic and fanciness. The overlap of a disruptive motif showed the overlap of disruptive print patterns with transparency and an overlap of different fabrics with a disruptive pattern. It represented spatial relationships of three dimensions as well as the maximization of visual illusion and the reinforcement of attractiveness. The blurring of a disruptive motif showed the pointage of disruptive motif, the pointage of image, value gradation, the whole blurring of a disruptive pattern cluster and stained appearance. It represented the obscurity of motif form, the uncertainty of object and double meaning. The trompe l'oeil of a partial background object showed the realistic and the painterly imitation of color and texture for partial objects through a close-up. It represented amazement and pleasure by illusion, scarcity and the decoration of surface and synecdochical remind. In conclusion, camouflage in fashion was weakened and modified from a classical military context by a unique expression of various motifs.

As a new trend in the development of urban public spaces, the use of right-angle LED screens perfectly combines building facades with naked-eye 3D visual effects, providing designers with a brand-new creative platform. How to create a realistic naked-eye 3D effect on a right-angle LED screen and bring an immersive visual experience to the audience has become a question worth exploring. So far, production companies have yet to announce the relevant design ideas and complete production methods. In order to explore the production principle and production process of the naked-eye 3D effect of the right-angle LED screen, we summarize the basic production principle of the naked-eye 3D impact of the right-angle LED screen through case analysis. Based on understanding the production principle, the actual case production test was carried out, and a complete production process of the naked eye 3D visual effect of the right-angle led screen was tried to be provided by off-line rendering. For the problem of how to deal with image deformation, we provide two production methods: post-production software correction and UV mapping. Among them, the UV mapping method is more efficient and convenient. Referring to this paper can help designers quickly understand the production principle of the naked eye 3D effect of right-angle LED screens. The production process proposed in this paper can provide a reference for production method for related project producers.

The purpose of this study is to analyze traditional stereo images (stereopsis), and study electronic methods to create stereo images using computer graphics technology on visualization of computer. Computer system can process image data and show results on its display. In the early days of computer era, most scientific research data was printed on paper as a procession of digits. These days, the visualization of computer graphics has a precise and realistic quality in its imaging technology. Some technological advances have been developed to not only display 2-dimensional geometry but also 3-dimensional stereo images to simulate virtual reality. In this study, [ have discussed the history of stereopsis, principles of stereo images and technological developments. Also I analyzed the components of stereo images, optical and electronic methods and visual systems which are used in computer graphics technology. I developed my own theories on possibilities for new methods of 3-dimensional stereo images.

The Miaos have their own unique and luxurious culture traditional and modern formed as they have experienced repeated fusion into and resistance against the Han Race or the Chinese in their long and old history. Taijiang County of Guizhou Provice, in which whey have been living, is endowed with natural beauty. Thus their culture enjoys abundant and diverse contents of artificial and natural character. Naturally, their costume reflects cultural and natural features in abundance and variety. This dissertation aims to investigate the artistic character of Miaos' traditional costume as reflected in patterns for their embroidery. As for the artistic character of the patterns for embroidery, the following were found. To begin with, the space in the Miaos' embroidery is, unlike the measurable three-dimensional space found in Greek art, unmeasurable and fantastic with its beauty, majesty and peculiarity. It is as if immersed in limitless space, they were in communion with gods and universe. Another characteristic is the use of image construction beyond mere imitation. Their mode of image construction was realistic in that patterns as a whole reveal an abstract form or meaning but separately they portray visual representations of concrete thins in nature. Still another is that sense of motion conveyed by the basic curve line is full of life. It was the result of using light rhythm breaking stereotypic balance and symmetry. Finally, the colouring was abstract, and a strong contrast between black and white was gorgeous and fantastic.

3D city model, which consisted of the 3D building models and their geospatial position and orientation, is becoming a valuable resource in virtual reality, navigation systems, civil engineering, etc. The purpose of this research is to propose the new framework to generate the 3D city model that satisfies visual and physical requirements in ground oriented simulation system. At the same time, the framework should meet the demand of the automatic creation and cost-effectiveness, which facilitates the usability of the proposed approach. To do that, I suggest the framework that leverages the mobile mapping system which automatically gathers high resolution images and supplement sensor information like position and direction of the image. And to resolve the problem from the sensor noise and a large number of the occlusions, the fusion of digital map data will be used. This paper describes the overall framework with major process and the recommended or demanded techniques for each processing step.
