The extraction and recognition of human motion characteristics need to combine biometrics to determine and judge human behavior in the movement and distinguish individual identities. The so-called biometric technology, the specific operation is the use of the body's inherent biological characteristics of individual identity authentication, the most noteworthy feature is the invariance and uniqueness. In the past, the behavior recognition technology based on the single characteristic was too restrictive, in this paper, we proposed a mixed feature which combined global silhouette feature and local optical flow feature, and this combined representation was used for human action recognition. And we will use the KTH database to train and test the recognition system. Experiments have been very desirable results.

The purpose of this study is to provide basic information to Korean fashion designers who wish to advance to the overseas collection. This is done through analyzing the design characteristics of Japanese young fashion designers, Tsumori Chisato, Commuun, and Limi Feu, who have successfully launched their designs into the Paris collection and became global fashion brands. Collections of each brand were analyzed by the overall fashion style and design elements. For the overall fashion style, Tsumori Chisato used a romantic style using details with various ornaments, whereas Commuun shows minimal style with a simple silhouette. Limi Feu expressed avant-garde style with experimental patterns. Moreover, these brands expressed different style to other brands by applying Japanese traditional clothes, patterns, and Japanese techniques in modern view point. In terms of design elements, these three brands used the H-line silhouette. Tsumori Chisato used loose fit; Commuun, slim line; and Limi Feu, boxy silhouette. In the case of colors, materials, patterns and details, Tsumori Chisato showed mix & match with various colors, materials, patterns and details. Commuun used mono tone with black & white using only one or two materials. Limi Feu usually used the color black with cotton. According to the style of the brand and region of the collection, the main characteristics of the design and the application of Japanese traditional elements can be different.

K-means algorithm is one of the most popular and widely used clustering method because it is easy to implement and very efficient. However, this method has the limitation to be used with fixed number of clusters because of only considering the intra-cluster distance to evaluate the data clustering solutions. Silhouette is useful and stable valid index to decide the data clustering solution with number of clusters to consider the intra and inter cluster distance for unsupervised data. However, this valid index has high computational burden because of considering quality measure for each data object. The objective of this paper is to propose the fast and simple speed-up method to overcome this limitation to use silhouette for the effective large-scale data clustering. In the first step, the proposed method calculates and saves the distance for each data once. In the second step, this distance matrix is used to calculate the relative distance rate ($V_j$) of each data j and this rate is used to choose the suitable number of clusters without much computation time. In the third step, the proposed efficient heuristic algorithm (Group search optimization, GSO, in this paper) can search the global optimum with saving computational capacity with good initial solutions using $V_j$ probabilistically for the data clustering. The performance of our proposed method is validated to save significantly computation time against the original silhouette only using Ruspini, Iris, Wine and Breast cancer in UCI machine learning repository datasets by experiment and analysis. Especially, the performance of our proposed method is much better than previous method for the larger size of data.

Throughout the rich human history, patterns have developed as a symbolic sign and representation of the inner psychology of human beings. Thanks to its intrinsic beauty and emotional richness, the flower has been utilized as a one of the major materials for patterns used in everyday life and art. As a product of nature, floral patterns have played a key role in fashion trends as a Surface Design with other elements of fashion design such as silhouette, fabric and color. Therefore, this research sought to identify the trends of floral patterns of women's garments that appeared at the four major global fashion collections (Paris, Milano, New York and London), and to analyze how importantly the fashion magazines' prediction were applied in the actual collections. Furthermore, the research aimed to suggest possible methods to utilize trend magazines for collections in the future. As a main research method, the authors investigated professional fashion literature and internet websites to extract a total of 4,681 items presented by sixteen designers who participated in the four major global fashion collections each time during the period of the 2012 S/S~2017 S/S seasons. First View Korea and Samsung Design Net were used as major sources for the pattern extraction and analysis. According to the analysis, floral patterns account for 31%(1,454 items) among the total number of patterns appearing in the four major global fashion collections(4,681 items). For the reflection ratio, Samsung Design Net recorded a 4% higher ratio(52%) than First View Korea(48%). Based on the data and analysis of this research, the authors expect that floral patterns in various forms will be continuously presented in fashion collections, and conclude that utilizing fashion magazines is highly useful due to their appropriate predictions.

This study aims to identify characteristics of neo-naturalism coming from periodical changes in the 21th society, culture based on naturalism and analyze the expressional and design characteristics of neo-naturalism on 2000s. For a research method, this study researched development of naturalism in fashion, and searched digital naturalism and ecology which are design paradigm effecting on neo-naturalism through literature research and preliminary study. Analyzing preliminary study on architecture, interior, fashion about digital naturalism and ecology design, concept of neo-naturalism identified and four expressional characteristics of neo-naturalism was classified, actual examples of neo-naturalism in 21th fashion were extracted and drew design characteristics. The results are as followings. Firstly, naturalism described nature as it is and developed according to the values and needs of the times. Naturalism in fashion showed natrual human body's curve, nature pattern and used natural materical focused on ideal beauty of nature. Secondly, neo-naturalism renews with the foundation of digital culture and ecology design paradigm, and focuses on the flexible possibility to express nature with digital, new media and formative art, and made the artificial nature uniting human-nature-environment as organic whole by ecology design paradigm. Thirdly, design of neo-naturalism divided four characteristics, nature's organic form, combination with the technology, ethical harmony with nature, global local design. The first characteristics of the nature's organic form are expressing silhouette of the nature's organic volume abstractly, the second ones of the combination with the technology are reinterpreting primitive nature contemporary with artificial sensibility of high technology, the third ones of the ethical harmony with nature are showing simple design and high-touch, and the forth ones of global local design are expressing cultural hybrid preserving vernacular design.

In this paper, we describe a method that can recognize gestures by obtaining motion features information with principal factor analysis from sequential gesture images. In the algorithm, firstly, a two dimensional silhouette region including human gesture is segmented and then geometric features are extracted from it. Here, global features information which is selected as some meaningful key feature effectively expressing gestures with principal factor analysis is used. Obtained motion history information representing time variation of gestures from extracted feature construct one gesture subspace. Finally, projected model feature value into the gesture space is transformed as specific state symbols by grouping algorithm to be use as input symbols of HMM and input gesture is recognized as one of the model gesture with high probability. Proposed method has achieved higher recognition rate than others using only shape information of human body as in an appearance-based method or extracting features intuitively from complicated gestures, because this algorithm constructs gesture models with feature factors that have high contribution rate using principal factor analysis.
