Efficient retrieval of image data is an important research issue in multimedia database. This paper proposes a new approach to a content-based image retrieval which allows queries to be composed of the local texture patterns and the slope components of contour points. The texture patterns extracted from the source image using the graylevel co-occurrence matrix and the slope components of contour points extracted from the binary image are converted into a internal feature representation of reduced dimensionality which preserves the perceptual similarity and those features can be used in creating efficient indexing structures for a content-based image retrieval. Experimental results of the image retrievalare presented to illustrate the usefulness of this approach that demonstrates the precision 82%, the recall 87% and the average rang 3.3 in content-based image data retrieval.

Motion of object in a video clip often plays an important role in characterizing the content of the clip. A number of methods have been developed to analyze and retrieve video contents using motion information. However, most of these methods focused more on the analysis of direction or trajectory of motion but less on the analysis of the movement of an object itself. In this paper, we propose the shape sequence descriptor to describe and compare the movement based on the shape deformation caused by object motion along the time. A movement information is first represented a sequence of 2D shape of object extracted from input image sequence, and then 2D shape information is converted 1D shape feature using the shape descriptor. The shape sequence descriptor is obtained from the shape descriptor sequence by frequency transform along the time. Our experiment results show that the proposed method can be very simple and effective to describe the object movement and can be applicable to semantic applications such as content-based video retrieval and human movement recognition.

This study is considered how retro design concepts that are used pop art can be expressed through overview of theories and cases, and suggested applying to retro design. As a result, we found first, concepts reflecting popular image, second, popular hero concepts simply represented pop art's feature. Third, there were no cases that are expressing the wounds made by political life. The most of cases expressed retro design with pop art representation techniques rather than reflecting of pop art's ideology or spirit. Pop art's retro design should be expressed as a modern style not only with reproduction of pop art, but also with designer's creativity and pop art's ideology and reinterpretation of formative meaning. Thus, it needs to set a concept by exploring of modern globalized mass media or daily life of people. Also, it should applying people's entertainment, spare time and fantasy to bright cheerful mood of pop art to express each area of design.

Movie clothing is what is recreated as a character in work after being worn for actors (or actresses). And it is not added for heightening only fantasy but it acts for heightening only fantasy but it acts for reinforcing the side of character or subject. Especially the clothing in color movie gets to have very psychological effect. Thus Accord-ing to the clothing the effect of the represen-tation style may become large and small. So as to make the gesture or attitude of each character valuable in accordance with the ac-tion and expression of the figure clothing is different from other device essentially One may attain various goals through the color of movie clothing, First movie clothing may show the vogue color of the time and the representative time color, Second the color of movie clothing helps one to able to recognize the socio-econmic position of character easily as the color to symbolize the specific jobs such as nurse soldier and doctor etc. Third the color of movie clothing may show the charcter temperament as to whether one is young or old and whether one has pessi-mistic temperament or one is extrovert or introversive etc. easily. Fourth setting the clothing color of hero as the color to set off helps it easy to distinguish from representation staffs. Fifty the whole color establishment of movie clothing gives help to expressing the at-mosphere of movie. Color is one of the most powerful means that the person in charge of clothing may express the character of movie. He should ex-press the feature of a wearer with the colors of each clothing through showing the lack of taste of characters or hinting the resistant character with the clothing color which is not suitable for situation or the conservative character with suppressed color etc. Thus he (or she) should express the clothing color which is suitable for being able to express each character by analyzing the work whole through script and grasping the character of each character so as to establish the clothing which is suitable for individual character.

In this paper, I am going to analyze a commercial film narrative focused on a temporal order through the theory of narrative discourse by Gerard Genette. Advertisements has a special quality or feature to be convertible into mythological hyper reality to advertise an product effectively. In this process, narrative in a commercial film has visual variations using a temporal order to show an glamorously advertisements in television. The reason that narrative in a commercial film is subject to variation with a temporal order, duration, frequency is to get some aesthetic effect for making sure people see them. Under the influence of postmodernism, image making like a pop-art became the first consideration in a commercial film with the consequence that representation as a signifier came to be more important than object as a signified. As a commercial film have more sensational image as a result of visual variation, images in a commercial film became vague so that it does not explain or express an advertising concept dearly. However, those aspects have assets that it gives the TV audience a room for interpretation in advertisements by themselves.

In this paper, we propose the method of multiple human action recognition on video clip. For being invariant to the change of speed or size of actions, Spatial-Temporal Pyramid method is applied. Proposed method can minimize the complexity of the procedures owing to select Motion Gradient Histogram (MGH) based on statistical approach for action representation feature. For multiple action detection, Motion Energy Image (MEI) of binary frame difference accumulations is adapted and then we detect each action of which area is represented by MGH. The action MGH should be compared with pre-learning MGH having pyramid method. As a result, recognition can be done by the analyze between action MGH and pre-learning MGH. Ten video clips are used for evaluating the proposed method. We have various experiments such as mono action, multiple action, speed and site scale-changes, comparison with previous method. As a result, we can see that proposed method is simple and efficient to recognize multiple human action with stale variations.

The contents of remote lectures are written by authoring tools or animation tools. Written contents then integrate existing medias, and are stored in a file type, which is added to the lecturing activities of lecturers. These files are stored according to the kinds of each authoring tool. So, there is no interchangeability and the efficiency of each media is not so good. Due to these structural features, it is not possible to do streaming lectures in on-line environments. In this study, a technique was suggested, which guarantees the interchangeability of remote lecturing contents using SMIL which is a synchronizing multimedia language. The suggested technique is an extended type of SMIL, and includes tags to represent the lectures of tutors which are the specific feature of remote lectures. Additionally, a model, which does streaming SMIL remote lecture contents through on-line, and which transfers control techniques are suggested. The remote lecture contents established by the proposed method can be applied to all authoring tools for remote lectures just by installing conversion modules, and can be a kind of expression model of the synchronizing model for streaming service in on-line environment.

The ontology alignment has two kinds of major problems. First, the features used for ontology alignment are usually defined by experts, but it is highly possible for some critical features to be excluded from the feature set. Second, the semantic and the structural similarities are usually computed independently, and then they are combined in an ad-hoc way where the weights are determined heuristically. This paper proposes the modified parse tree kernel (MPTK) for ontology alignment. In order to compute the similarity between entities in the ontologies, a tree is adopted as a representation of an ontology. After transforming an ontology into a set of trees, their similarity is computed using MPTK without explicit enumeration of features. In computing the similarity between trees, the approximate string matching is adopted to naturally reflect not only the structural information but also the semantic information. According to a series of experiments with a standard data set, the kernel method outperforms other structural similarities such as GMO. In addition, the proposed method shows the state-of-the-art performance in the ontology alignment.

Objects such as products, product reviews, and user profiles are important in e-commerce domain. Vector is one of the most widely used object representation scheme. Information of e-commerce objects may be modeled by vectors in which the featured values are assigned to various dimensions. E-commerce objects are in general quantitatively large while some are similar or even same in reality. It Plays, therefore, an important role to measure the similarity between objects. In this paper, we survey the state-of-the -art vector similarity measures. Similarity measures are analyzed to feature the algebraic characteristics and relationship of those, and upon which we classify the related measures accordingly. We then present such features that standard vector similarity measures should convey.

Advertisements provide consumers with in-formation and knowledge about products and help a society to sustain homogeneity by actively reflecting important characteristics of mass culture. Yet this reflection is a selective and purposeful representation by the party of the fashion manufactures and carries the intention of stimulating and augmenting desire for commodities aiming to perpetuate capitalism. This study understood this selective reflection of mass culture by advertisements as a feature of hegemonic struggle between/fashion business and consumers and defined the values selected by advertisements as ideologies supporting the consumption ideology of capitalism. The purpose of this study was to examine the contents of the ideologies expressed in the clothing advertisements in women's magazines to persuade consumers into consumption. The method of study was mainly qualitative with subsidiary citations from the results of content analysis. The objects of analysis were clothing advertisements in 1996 issues of CeCi and Woman Sense, which were identified as the two most popular women's monthly magazines. The ideologies identified were ideologies concerning (1) Self Identity, (2) Sensibility, (3) Sex Role, (4) Globalism, (5) Youth, (6) Leas-ure and Pleasure. Repeated and insisted as natural and true, there values were proposed to be believed as common senses and studies re-port that values of advertisements are ac-cepted as more readily as they are more unreasonable, and the acts and behaviors expres-sed within advertisements are often imitated in real life situations. Therefore, it is highly probable that these values emphasized within advertisements are enacted in thoughts and behaviors of consumers' real life. Accordingly the author suggests that critical interpretation of advertisements is seriously required to fully understand the commodity ridden post industrial society of today and to lead a subjective life within it.
