Images with lower illumination from the light source or with dark regions due to shadows, etc., can improve subjective image quality by using retinex-based image enhancement schemes. The retinex theory is a method that recognizes the relative lightness of a scene, rather than recognizing the brightness of the scene. The way the human visual system recognizes a scene in a specific position can be in one of several methods: single-scale retinex, multi-scale retinex, and multi-scale retinex with color restoration (MSRCR). The proposed method is based on the MSRCR method, which includes a color restoration step, which consists of three phases. In the first phase, the existing MSRCR method is applied. In the second phase, the dynamic range of the MSRCR output is adjusted according to its histogram. In the last phase, the proposed method transforms the retinex output value into the display dynamic range using a logarithm transformation function considering human visual system characteristics. Experimental results show that the proposed algorithm effectively increases the subjective image quality, not only in dark images but also in images including both bright and dark areas. Especially in a low lightness image, the proposed algorithm showed higher performance improvement than the conventional approaches.

The communication designer in the multimedia age should have a consideration that the sound also can be an important expression element to transmit ones thought as well as the visual sense like color, shape and motion. As you already know, someones thought can be better understood when transmitted to others using the visual and auditory senses together than using the visual or auditory sense alone. The meeting of sight and hearing bases on the synesthesia. For example, low sound reminds a person of dark color and high sound usually reminds light color. And a percussion instrument reminds a person a circle and melody reminds a line. The visual and auditory senses In communication of the multimedia age should act as an independent expression element gotten out of the synchronizing that just serves simple sight and related sound at the same time. Interaction between sight and hearing arose a different emotion that cannot be happened just by one element alone. So, the programs of communication design education in this multimedia age should fulfill the requirement that it can develop ones expression ability through the understanding of interaction between sight and hearing. In this study, we suggest the education programs Classified into following categories; audio visual Gestaltung, audio visual moving graphics, audio visual design.

This study will examine the visual composition by which Secretly Greatly, in a circumstance that even the good original Manhwas or Webtoon have not made a hit on the market until now, could attract the spectator, in other word, illustrate the analogousness of the images through analysing visual texts. The study draw, first of all, a meaning of the box office performance caused by analogousness of image, that is similarity between the webtoon and film. In addition, the study will come up with an answer to the question that the webtoon, not in a temporary trend but in a sustainable form, can make itself develop. For this, the study suggests a meaning, worth and importance of the transformation, analysing visual components of a webtoon to film adaptation, Secretly Greatly. It primarily ranges over visual components, mise-en-scène identified with its expression formula, frame to frame changes and colour and tone. The examination sets the cinema's visual expression manner against the webtoon's on their concrete components: the size of scene, movement, color and tone, narrative condition and its background, spatial composition and depth, contrast, expression manner and disposition manner.

Confucius, whose life coincided with the Warring States period of China, is one of the most respected sages in world history whose teachings and life produced countless disciples in China, Korea, and Japan. There are innumerable pictures, sculptures, and other artworks that portray memorable deeds of Confucius and interesting anecdotes that involve his pupils. One of the most popular subjects for these Confucian portrayals is the anecdote in which Confucius and his pupil, Zhi Ru, discover a tilting vessel at an ancestral shrine in the Lu dynasty and use it to understand the doctrine of the mean. The vessel becomes the basis for the famous Chinese expression, "the cautionary vessel beside one's seat," which is nowadays used to denote one's motto for life. Portraits of these tilting vessels can be divided between those showing the vessels only and others that show Confucius observing the vessels. The former serve as visual reminders, for rulers and policy makers, of the doctrine of the mean that is necessary to fair and righteous governance. The latter form part of the pictorial biography of Confucius with educational content and messages. Interestingly, portraits of Confucius observing or studying tilting vessels have been famous among members of the royal court and the literati, circulated either as single artworks or included in the folding screens of human portraits. Portrayals of other Confucian anecdotes are mostly found in albums that visualize the genealogy of the Way; in contrast, the portraits of Confucius and the tilting vessels were included in folding screens that were popular among the literati that enjoyed stylish works of art and antiques. The portraits of tilting vessels thus highlight the diverse functions and symbolic value of human portraits. This study classifies the portraits of tilting vessels into various forms, and analyzes the period-and objective-dependent changes and characteristics in these portraits. With its exploration of the diverse functions and aspects of portraits of Confucian anecdotes, this study will shed new light on how ancient artists reanimated the lives of great sages and how these artworks differ in their expressions and styles.

MPEG-4 AVC is an international video coding standard that is being developed. The standardization is mainly targeted at a very high compression ratio. MPEG-4 AVC is a general video coding technology that may be used in various applications. Therefore, MPEG-4 AVC needs an efficient rate control method to be applied in various communication environments. This paper is based on the rate control method that considers human visual characteristic. In this paper, we propose the constant bit rate control method using adaptive quantization and scene change detection. Experiments performed using various test images and experimentation results exhibits a favorable performance over existing rate control methods.

The multimedia that is characterized by multi-media, multi-features, multi-representations, huge volume, and varieties, is rapidly spreading out due to the increasing of application domains. Thus, it is urgently needed to develop a multimedia information system that can retrieve the needed information rapidly and accurately from the huge amount of multimedia data. For the content-based retrieval of moving picture, picture information is generally used. It is generally used when video is segmented. Through that, it can be a structural video browsing. The tasking that divides video to shot is called video segmentation, and detecting the cut for video segmentation is called cut detection. The goal of this paper is to divide moving picture using HMMD(Hue-Mar-Min-Diff) color model and edge histogram descriptor among the MPEG-7 visual descriptors. HMMD color model is more familiar to human's perception than the other color spaces. Finally, the proposed retrieval system is implemented as hardware.

This study conducts data visualization of common climax patterns of Korean blockbuster films to analyze shots and evaluate scene (subplot unit) arrangement. For this purpose, a model of editing patterns is used to analyze how many climax patterns a film contains. Moreover, a system, which automatically collects shot images and classifies shot sizes of collected data, is designed to demonstrate that a single scene is composed based on a climax pattern. As a scene is a subplot and thus its arrangement cannot fully be analyzed only by climax patterns, dialogues of starring actors are also used to identify scenes, and the result is compared with data visualization results. It detects dialogues between particular actors and visualizes dialogue formation in a network form. Such network visualization enables the arrangement of main subplots to be analyzed, and the box office performance of a film can be explained by the density of subplots. The study of two types comparison analysis is expected to contribute to planning, plotting, and producing films.
