The aim of this study is to serve as a stepping stone to outlook changes in men's fashion based on gender characteristics and the design proposal as a reference to shirts design for men's wear brands. This study is a theoretical work extracted from related books, dissertations, and web- resources referenced. Research method is as followed. It is based on the four main collections from S/S 2001 to S/S 2010 and selected designer brands among the most influential foreign men's fashion designer brands which have show cased their collections of 19 seasons in the last 10 years. These are what the study has found out. Firstly, the shoulder-line which used to be straight and hard in men's dress shirt has changed to comfortable curved line which falls from the shoulder to sleeve. Silhouettes were mainly shaped to an hourglass or slim silhouette representing the body curve line. Unlike how the masculine beauty was emphasized through the straight line, men's dress shirts nowadays used curved line for softness. Secondly, there were various designs with decorations added to the basic structure, making it no different from women's blouse and blurring the line between men's and women's fashion. Thirdly, colors were normally in bright ones. Tones were often in pale tone which used to be the women's color. Also choosing shades of yellow or red was a remarkable change in men's wear. Fourthly, through varying patterns and texture there were many shirts that gave clear visual effect. There were approximately equal portions of patterns with feminine image like natural patterns, abstract patterns, or small patterns and patterns with masculine image.

In this paper, a new disparity detection algorithm which is robust to noise is presented. It detects the disparity of an arbitrary pixel through the iterative competition with neighbor pixels in the range of disparity. A diffusion process to improve stereo matching confidence is used prior to detecting disparity of an arbitrary pixel. It is used for aggregating initial matching measure of the difference map. If the image region for matching is too small, a wrong match might be found due to noise. On the contrary, the region is too big, it results in blurring of object boundaries. Therefore, we decide the image region for matching by using the diffusion process for aggregating matching measure, then detect the true disparity with proposed competition method to the distribution of matching measure. Through the proposed method we get the result of improving matching rate of 6.96% with real stereo imge. From the simulation with the stereo imge, the proposed disparity detection method significantly outperforms the conventional method to matching rate.

Considering Korean feminist theatre is not successful at all these days, it is needed to find the reasons of its crisis. As two Korean feminist theatre Scholars argued, the crisis owed to the structural problem from the start. That is the Korean feminist theatre started and developed depending on the imported popular feminist plays without social and cultural self-consciousness. Once the imported feminist theatres were flourished, some theatre companies pursued the commercial success blurring the feminist issues. It was resulted into the intentional ignorance in and out of the theatre society. While, some feminist plays were too inclined to the agit-prop without artistic sophistication. This essay tries to examine how the feminist theatres have been developing and what kinds of feminist performances have been made until now. And it intends to emphasize that the play text should be based on the Korean women's past, present, and future reality. Besides, they have to delve into the problem by which the Korean women were trapped in historical, social, and cultural environment. To make the women's matter the social issue at present and fur the future, the Korean feminist theatre should re-find its place as the socio-cultural forum. First, Korean theatre should cooperate with the other women's group crossing the different disciplines of the society, the culture, the politics etc . Secondly, we need to observe and watch where and how the distortion happens in women's matter, and react to correct it. Thirdly, we need to discover, to support, and to protect the women centered perspective of some playwrights as well as the performers. Co-writing or co-performing is also very positive to diversify the women's subjects. Lastly, to protect the feminist theatre against the consumerism, they need to have the financial support from the government or some civil society.

Among various methods proposed earlier, fuzzy image filtering is usually one of the favored techniques because it has less blurring effect and the decrease of noise removal rate after filtering. However, fuzzy filtering is ineffective on color images since it is firstly developed with gray scale. Thus, in this paper, we propose a fuzzy filtering algorithm for color images. First, we divide RGB color information from image into three channels of R, G, and B and judge the possibility of each pixel with mask by fuzzy logic independently. The output pixel value might be the average or median according to the degree of noise. Our experiment successfully verifies the effectiveness of new algorithm in color image.

Aiming at motion analysis and compensation, it is essential to conduct motion detection with images. However, motion detection and tracking from low-altitude images obtained from an unmanned aerial system may pose many challenges due to degraded image quality caused by platform motion, image instability and illumination fluctuation. This research tackles these challenges by proposing a modified joint transform correlation algorithm which includes two preprocessing strategies. In spatial domain, a modified fuzzy edge detection method is proposed for preprocessing the input images. In frequency domain, to eliminate the disturbance of self-correlation items, the cross-correlation items are extracted from joint power spectrum output plane. The effectiveness and accuracy of the algorithm has been tested and evaluated by both simulation and real datasets in this research. The simulation experiments show that the proposed approach can derive satisfactory peaks of cross-correlation and achieve detection accuracy of displacement vectors with no more than 0.03pixel for image pairs with displacement smaller than 20pixels, when addition of image motion blurring in the range of 0~10pixel and 0.002variance of additive Gaussian noise. Moreover,this paper proposes quantitative analysis approach using tri-image pairs from real datasets and the experimental results show that detection accuracy can be achieved with sub-pixel level even if the sampling frequency can only attain 50 frames per second.

This paper proposes a composite filter for noise reduction of image. To improve the image quality by reducing the noise in the liver ultrasound image, we tried to help the accurate image analysis. In the experiment, the top seven composite filters were selected by combining the Gaussian blur filter, the sharpening filter, and the median filter using the ATS-539 ultrasonic phantom, and applied to the ultrasound image in which this was done. As a result, it was found that the values of SNR, CNR and MSR all increased when the top seven composite filters were applied. In addition, PSNR of more than 30 dB, close to SSIM 1 showed that the image loss rate is small. Therefore, the appropriate application of the proposed composite filter in this research will be useful for accurate video reading and analysis.

This study presents an investigation into the ways to detect the areas of object movement with Kinect's Depth Frame, which is capable of receiving 3D information regardless of external light sources. Applied to remove noises along the boundaries of objects among the depth information received from sensors were the blurring technique for the x and y coordinates of pixels and the frequency filter for the z coordinate. In addition, a clustering filter was applied according to the changing amounts of adjacent pixels to extract the areas of moving objects. It was also designed to detect fast movements above the standard according to filter settings, being applicable to mobile robots. Detected movements can be applied to security systems when being delivered to distant places via a network and can also be expanded to large-scale data through concerned information.
