To assist radiologists for the characterization of breast masses, Computer-aided Diagnosis(CADx) system has been studied. The CADx system can improve the diagnostic accuracy of radiologists by providing objective information about breast masses. Morphological and texture features were extracted from the breast ultrasound images. Based on extracted features, the CADx system retrieves masses that are similar to a query mass from a reference library using a k-nearest neighbor (k-NN) approach. Eight similarity measures of distance, Euclidean, Chebyshev(Minkowski family), Canberra, Lorentzian($F_2$ family), Wave Hedges, Motyka(Intersection family), and Cosine, Dice(Inner Product family) are evaluated by ROC(Receiver Operating Characteristic) analysis. The Inner Product family measure used with the k-NN classifier provided slightly higher performance for classification of malignant and benign masses than those with the Minkowski, $F_2$, and Intersection family measures.

The feature-based visual SLAM requires 3D positions for the extracted feature points to perform 3D-2D motion estimation. LiDAR can provide reliable and accurate 3D position information with low computational burden, while stereo camera has the problem of the impossibility of stereo matching in simple texture image region, the inaccuracy in depth value due to error contained in intrinsic and extrinsic camera parameter, and the limited number of depth value restricted by permissible stereo disparity. However, the sparsity of LiDAR data may increase the inaccuracy of motion estimation and can even lead to the result of motion estimation failure. Therefore, in this paper, we propose three interpolation methods which can be applied to interpolate sparse LiDAR data. Simulation results obtained by applying these three methods to a visual odometry algorithm demonstrates that the selective bilinear interpolation shows better performance in the view point of computation speed and accuracy.

Previous 2D-3D conversion methods to generate 3D stereo images from 2D sequence consist of labor-intensive procedures in their production pipelines. This paper presents an efficient 2D-3D conversion system based on scene structure reconstruction from image sequence. The proposed system reconstructs a scene space and produces 3D stereo images with texture re-projection. Experimental results show that the proposed method can generate precise 3D contents based on scene structure information. By using the proposed reconstruction tool, the stereographer can collaborate efficiently with workers in production pipeline for 3D contents production.

In this study, the pattern of texture was developed by applying the pattern shown in the Amita Yeoraebul and the Avalokitesvara with symbolism suitable for children's clothing. In addition, the design and the manufacturing of a children's wearable Hanbok were attempted, and the results are as follows: Amitha Yeoraebul is a Buddha who oversees paradise in Buddhism, and Avalokitesvara controls both paradise and the real world and provides mercy. Applying the various patterns in the Buddhist paintings, four daily hanboks for children were produced using patterns featuring symbolic the meanings of large round original patterns chrysanthemums, turtles, and lotus patterns. The lotus symbol represents love, nobility, and wealth, while the turtle symbol represents longevity, the chrysanthemum pattern symbolizes auspiciousness, and the large round original pattern means a constant continuation. To maintain the traditional hanbok form but allow convenient wear it in daily life, it is made in the jeogori + shorts, vest + long pants, and one-piece + jacket style. Currently, the daily dress of Hanbok and the modernization of traditional Korean clothes are being promoted. At this point, the study developed Hanbok fashion products that contain symbolic stories suitable for children are trying to maintain the image of traditional culture as much as possible.

Today, many people seek for their own personal character which is distinguished from another people and they utilize fashion coordination as the was of expression their own image. In addition, interest in electronic commerce and cuber shopping mall on the internet is increasing. For this reason, visual and interesting virtual fashion coordination system is needed. The purpose of this study is to propose possibility of fashion coordination by virtual 3D model. For this study, 1. We make a 3D standard body model by automatic generation. 2. We make 3D fashion item (sleeveless top and flare skirt) by automatic generation. 3. We combine 3D body model with fashion item by special point, grouping and gap being between body and clothes. 4. We make textile palettes and textile DB for texture mapping and rendering. As a effect of this study, 1. It can give the chance to coordinate clothes suitable for their own character and bodyshape on the cuber space more speedily and variously. 2. It can help fashion internet shopping mall company can save a time, expenses and tries to advertise their new products, offer service for customers and lead customers to purchasing. 3. It can accumulate a database of design and textile for using by fashion and textile industry.

There are some problems in robot navigations with a single kind of sensor. We propose a system that takes advantages of both CCD camera and ultrasonic sensors for the concerning matter. A coordinate extraction algorithm to avoid obstacles during the navigation is also proposed. We implemented a CCD based vision system at the front part of the vehicle and did experiments to verify the suggested algorithm's availability. From experimental results, the error rate was reduced when a CCD camera was used rather than when only ultrasonic sensors were used. Also we can generate path to avoid those obstacles using the measured values.

With the development of mobile devices and intelligent surveillance system loaded with pan/tilt cameras, object tracking with non-stationary cameras has become a topic with increasing importancy. Since it is difficult to model a background image in a non-stationary camera environment, colors and texture are the most important features in the tracking algorithm. However, colors in the background similar to those in the target arise instability in the tracking. Recently, we proposed a robust color based tracking algorithm that uses an area weighted centroid shift. In this letter, we update the model such that it becomes more stable against background colors. The proposed algorithm also incorporates time filtering by adding an additional energy term to the energy functional.

T-shirt has changed into advanced and stylish outwear by new paradigm, taste of consumer, awareness of recycling, spread of subculture, DIY culture, refusal of standardization and pursuit of high quality goods, etc. The purpose of this study was to analyze aesthetic characteristics of t-shirt designs that changed into diverse designs in world fashion college since 2000. The method of this study was to analyze documentaries, fashion magazines and internet fashion site. Aesthetic characteristics of t-shirt designs were expressed in deconstruction, mixture, integration and imitation. And each of external expressions and internal meanings was as follows: First, deconstruction was expressed in partial cutwork and three dimensional texture by sewing and construction drape. It means breaking the conventional structure and break-ing the boundary of t-shirt and another item and possibility of multi-vocal analysis. Second, mixture was expressed in collage of diverse ornaments, diverse fabrics and diverse patterns. It means exceeding the limit of material, elaboratenes and high quality of handwork, reflection of self-identity, brand image, fashion trend, consumer's psychology and mind of experimentation and couture. Third, integration was expressed in extension of length, width, use and style. It means unification of functions, deconstruction of items and extension of meanings and images. Forth, imitation was expressed in stain of dye, irregular and ripped sign, cut out, rough warp, drawing and washing, etc. It means subculture, rarity value, monopolization, diversity, familiarity, yearning and uniqueness.
