Performance of the interpolation algorithm used in the technique of bi-dimensional empirical mode decomposition directly affects its popularization and application, so that the researchers pay more attention to the algorithm reasonable, accurate and fast. However, it has been a lack of an adaptive interpolation algorithm that is relatively satisfactory for the bi-dimensional empirical mode decomposition (BEMD) and is derived from the image characteristics. In view of this, this paper proposes an image interpolation algorithm based on the particle swarm and fractal. Its procedure includes: to analyze the given image by using the fractal brown function, to pick up the feature quantity from the image, and then to operate the adaptive image interpolation in terms of the obtained feature quantity. All parameters involved in the interpolation process are determined by using the particle swarm optimization algorithm. The presented interpolation algorithm can solve those problems of low efficiency and poor precision in the interpolation operation of bi-dimensional empirical mode decomposition and can also result in accurate and reliable bi-dimensional intrinsic modal functions with higher speed in the decomposition of the image. It lays the foundation for the further popularization and application of the bi-dimensional empirical mode decomposition algorithm.

This study intends to analyze T-shirt designs, particularly in connection with pop art. 444 pieces of T-shirts which conveyed the pop art spirits of well-known designers were selected for five years from 2001 to 2005, through fashion magazines(Collection: Dong-ah TV, Collezioni: Italy). The findings are as follows. As for formative characteristics of pop art in T-shirts, previous studies were analyzed to set classifications criteria such as popularization of images, eroticism, lettering and graffiti, assemblage. The design factor of the image popularization includes everyday images, cartoon, celebrities, and caricature. Everyday images ranked first followed by cartoon, caricature and celebrities. The design factor of eroticism ranges from the see-through look, partial exposure of human body, symbolization of underwear, and to printing of sexy images. The see-through look was ranked first, followed by partial exposure of human body, symbolization of underwear, and printing of sexy images. The design factor of lettering and graffiti encompasses letters, numbers, symbols and logos. Adoption of letters, numbers or symbols was ranked first, followed by brand logos and graffiti. The design factor of Assemblage is closely related to a three-dimensional effect. Varied expressions are possible: combination of two different textiles and fusion of textile and non-textile. Combination of two different textiles are higher than fusion of textile and non-textile.

According to a popularization of the Internet and digital lifestyle, digital watermarks have been proposed for protection of copyrighted multimedia content. In blind watermark detection, which an original image is not provided, robustness against geometric distortion and compression remains challenging. In this paper, we propose a new perceptual blind discrete wavelet transform - discrete Fourier transform (DWT-DFT) composite watermarking scheme that is robust against both general linear transform and JPEG compression. This algorithm constructs an image-dependent watermark in the most significant DWT coefficients, which is determined by using a hierarchical tree structure. Strength of watermark is determined from a just-noticeable difference (JND) profile of a perceptual model. Furthermore, a desired template is inserted into DFT domain of the watermarked image. In new manner, a cross-ratio of four collinear points is used for detecting the template. Experimental results have showed that the proposed scheme is robust against general linear distortion, JPEG compression and various general kinds of attacks in the Stirmark 3.1 watermark evaluation tool.

The purpose of this study is to analyse the fashion image behind the colour black formed by existentialism in the 20th century. Human beings started to ask themselves questions about their nature and existence by undergoing two world wars in the 20th century. Existentialism was born out of these philosophical thoughts and in particular, French existentialists led the public discourse of the time and expressed their philosophical thoughts and ideas through black fashion. Therefore we revealed the existentialistic meanings of black by studying the French existentialist ideology and their black fashion. The thoughts of existentialism became popularized in France by French philosophers. Sartre especially played a big role in the popularization of existentialism in France. The black fashion worn by existentialists became popularized along with the ideology that it expressed. Sartre's thoughts on existentialism are summarized in existence Precedes Essence, self-reliance, and engagement. From these, the fashion image behind the colour black formed by existentialism was analogized to resistant image, nihilistic image and self-reliance image.

The vision system is easy to use the exclusive use as a independent computer system but it is not much popularization by reason of expensive and difficult to adapt to the various fields, because it is easy to the existed computer system, the price is cheap and also it can use to the various measurement purpose which user wanted and programed. The measurement method of the vehicle axle casing nut welding part is that measure the value of the welding part to adapt the actual operation program from using the ratio between the actual length of the standard specimen and the length of image, to measure the ratio between the actual product and the camera image. A defect is found by the assembled visual inspection system. The inspection algorithm which estimates the quality of welded product is developed and also, the software program which processes the automatic test function of the inspection system. We make the foundation of the inspection automatic system and we will help to apply other welding machine.

purpose of this study was to trace historically the causes of the visual inconsistency of seXual ilT'age in dress with versatile perspectives. For this purpose, theoretical studies about the concepts of sexuality in dress were precceded. To trace the factors of the visual inconsistency of sexual image in dress, historical studies from ancient Egypt to modern ages were done. And then, the factors of the visual inconsist\ulcornerency of sexual image in dress were identified. The synthetic results were as follows; L The visual inconsistency of sexual image in dress shows the phenomena that men introduce the traditional feminine image in dress (ex. X silhouette, skirts), whereas women do the traditional masculine image (ex. Y silhouette, pants), which arouse androgynous image in appearance. And, it also indicates that men or women wear the dress excluded the traditional masculine image as well as the traditional feminine image, which arouse neutral image in appearance. 2. The visual inconsistency of sexual image in dress have been existed historically, from Egypt to modern ages. 3. The visual inconsistency of sexual image III dress was caus~d by various factors as follows; First, ideal beauty of the times which did not distinguish between masculinity and femininity resulted in the visual inconsistency of sexual image in dress. Second, as a means of seeking pleasure, the visual inconsistency of sexual image in dress was used. Third, as a means of expressing ideology, the visual inconsistency of sexual image in dress was selected. Forth,in religious meaning,the visual inconsistency ofl sexual image in dress was appeared. Fifth,popularization of sports and occupational role made woman adopt the masculine image in dress in view of the aspects of functionalism. Sixth,Undevelopment of taloring contributed to generate androgenous image in dress.

Due to the popularization of fashion, it is important for consumers to find out under what kinds of reasons consumers choose and prefer the clothing products as consumers are interested in clothing and have variety of their styles to choose This study is to classify the self-image of the middle-aged women and examine the characteristics of each group and also to inquire into the evaluation of clothing by each group. Data are collected through a self-administered questionnaire survey from 4 to October 31, 2005 from 350 middle-aged women in Daegu; 275 are used for the data analysis. Data analysis is performed using SPSS Package, which included cluster analysis, factor analysis, ANOVA, Duncan's multiple range test, and chi-square test. The results are as follows: 1. As a result of factor analysis of self-image, the five factors which are intelligent image, social image, fashionable image, female image, bold image are extracted. Besides, as a result of cluster analysis, the three types which are female-type, neuter-type, male-type are classified. 2. The middle-aged women regard the classic style as their best style for outgoing and then they like the casual style, elegant style, dramatic style in order. 3. As a result of factor analysis for clothing image, the four factors which are dignity, attraction, simplicity activity are extracted. 4. According to self-image types, there are differences for clothing image and preferring clothing styles. While female-type groups choose the elegant style, neuter-type groups regard the classic style as their best style and male-type groups regard the casual style as their best style. In case of daring style, the preference shows the lowest among all the types unrelated to self-image types.
