Purpose: Accurate clinical evaluation of the alignment of the calcaneus relative to the tibia in the coronal plane is essential in the evaluation and treatment of hindfoot pathologic condition. Previously described standard anteroposterior, lateral, and oblique radiographic methods of the foot or ankle do not demonstrate alignment of the tibia relation to the calcaneus in the coronal plane. The purpose of this study was to introduce hindfoot coronal alignment view. Material : 1) Both feet were imaged simultaneously on an elevated, radiolucent foot stand equipment. 2) Both feet stood on a radiolucent platform with equal weight on both feet. 3) Both feet are located foot axis longitudinal perpendicular to the platform. 4) Silhouette tracing around both feet are made, and line is then drawn to bisect the silhouette of the second toe and the outline of the heel. 5) The x-ray beam is angled down approximately $15^{\circ} to $20^{\circ} Result : 1) This image described tibial axis and medial, lateral tuberosity of calcaneus. 2) Calcaneus do not rotated. 3) The view is showed by talotibial joint space. Conclusion: Although computed tomographic and magnetic resonance imaging techniques are capable of demonstrating coronal hindfoot alignment, they lack usefulness in most clinical situations because the foot is imaged in a non-weight bearing position. But hindfoot coronal alignment view is obtained for evaluating position changing of inversion, eversion of the hindfoot and varus, valgus deformity of calcaneus.

In this paper, we propose a new 3D object retrieval system using the shape information of 2D silhouette images. 2D images at different view points are derived from a 3D model and linked to the model. Shape feature of 2D image is extracted by a region-based descriptor. In the experiment, we compare the results of the proposed system with those of the system using curvature scale space(CSS) to show the efficiency of our system.

The purpose of this paper is to propose ways to remove false color noise (FCN) generated during de-mosaicing on RGB Bayer pattern images. In case of images sensors adapting Bayer pattern color filters array (CFA), de-mosaicing is conducted to recover the RGB color data in single pixels. Here, FCN phenomena would occur where there is clearer silhouette or contrast of colors. The FCN phenomena found during de-mosaicking process appears locally in the edges inside the image and the proposed method of eliminating this is to convert RGB color space to YCbCr space to conduct smoothing process. Moreover, for edges where different colors come together, censoring based smoothing technique is proposed as a way to minimize color blurring effect.

The purpose of this study is to discover the techniques and the trends of expression of modern knitwears focusing on the 1990's after. The resorts of this study is as follows: The techniques of expression of knitwears are classified by the sections on the techniques and the styles of expression. The divisions into the techniques are knitting, crochet, macrame, netting, knotting. And the divisions into upon the styles of expressions are color, pattern, texture, relief and seeing through The techniques of expression on the modern knitwears are expressed characteristic of variety and composition, are expended to the art wear by translated into art. According to a wide sense, ecology, ethnic, modern are the themes of knitwears of 1990's after. The characteristic technique of expression according to the themes are expressed by the harmony of image, yarn, color, silhouette, techniques of expression. The modern knitwears are tried by mixed and various techniques, developed to the area of art wear, escaping from simple and practical item.

Fashion photographs from leading monthly fashion magazines in 1990s were analyzed. The types and the formative feature characteristics and the aesthetic values of domestic retrospective fashion were studied. The major conclusions of the study are as follows 1. The types of domestic retro fashion were historicism, ethnic, ecology. Retro fashion was expressed through applying and reappearing silhouette, detail. fabric and image of the costumes of the past. 2. Renaissance. Baroque, Rococo styles and the costumes and styles of 1960s and 1970s were mainly applied in domestic fashion. 3. Orientalism was emphasized and Korean traditional styles and Chinese costumes were expressed mainly in domestic fashion. Fashion trends recurrent and intimate to the nature were expressed in patterns, fabrics, dyeing and silhouettes of nature. 4. The formative feature characteristics of domestic retro fashion were recurrence, purity. tradition and decoration. As retro fashion applies costumes of the past newly, it supplies unlimited possibilities to the present fashion which seeks versatility.

The equipment of industrial robot in manufacturing and assembly lines has rapidly increased. In order to achieve high productivity and flexibility, it becomes very important to develop the visual feedback control system with Off-Line Programming System(OLPS). We can save much efforts and time in adjusting robots to newly defined workcells by using OLPS. A proposed visual calibration scheme is based on position-based visual feedback. The calibration program firstly generates predicted images of objects in an assumed end-effector position. The process to generate predicted images consists of projection to screen-coordinates, visible range test and construction of simple silhouette figures. Then camera images acquired are compared with predicted ones for updating position and orientation data. Computation of error is very simple because the scheme is based on perspective projection which can be also expanded to experimental results. Computation time can be extremely reduced because the proposed method does not require the precise calculation of tree-dimensional object data and image Jacobian.

In this paper, we propose a novel post-processing method of semantic segmentation from indoor scenes with RGBD inputs. For accurate segmentation, various post-processing methods such as superpixel from color edges or Conditional Random Field (CRF) method considering neighborhood connectivity have been used, but these methods are not efficient due to high complexity and computational cost. To solve this problem, we maximize the efficiency of post processing by using depth superpixel extracted from disparity image to handle object silhouette. Our experimental results show reasonable performances compared to previous methods in the post processing of semantic segmentation.

This study tried to research on clothing styles of show hostess in the cable television home-shopping network program. Especially, show hostess's clothing styles were classified into 5 sections according to selling products, that is baby goods, insured goods, underwear, bedclothes and beauty goods. item is examined 7 levels by texture, color, clothing item, fashion image, fashion trend, fashion type, and fashion silhouette. The results showed that significant correlations between show host's clothing and selling products. The another findings of this study is that show hostess's clothing is aimed at the taste of main consumer such as housewife. Conseguently this study reaffirms the importance of the shopping hostess's clothing influnce according to selling products's characteristics.

This study aims to understand the importance of stage costumes, examine and analyze their theoretical ideas in order to propose new designs and support the studies and advances of stage costumes in play. The writer operated and produced the costume designs of Shakespeare's play, Measure for Measure as a costume director, which was played on September 16 to 17, 2011 at the Haneul Theater in the National Theater of Korea and on September 3, 2011 at the Jinnam Munye Theater. The study was followed by 1. Proposing a new modern point of view of the design of the traditional dresses in 16th to 17th centuries. 2. Expressing a symbolism based on personality, role and nature of characters in the play by a creative and modern image of the dress in color, line, and silhouette, which are basic factors of a clothes design.
