In fashion, there are various cultural aspects that exist in complexity, where according to the era, even fashion items newly develop and prevail into various designs in the organic function with reality of related cultural phenomenon and aesthetic aim. Among the fashion items, the shoe is historically considered as the shield from lust and also the provision of praise against the most emotional incitement. Mankind has started wearing shoes out of the functional purpose of protection since the ancient Egyptian times. Thereafter humankind has been creating shoes artistically in respect to shape, color, and quality of material, etc, as an expression of aesthetical awareness and introspective desire for beauty. As modern fashion increasingly regards the total fashion image much more important than each items consisting the whole outfit, the role of shoe became essential more than ever. Contrary to its relative importance, little academic attention was given to this area yet, while prestigious museums and galleries in Europe and the USA have held exhibitions of shoes in view of both historical and artistic aspects. This study aims to make a historical inquiry of western shoes. through which their aesthetic values can be drawn. Literature on this subject including aesthetics, history of costume and arts were referred. Fashion magazines and catalogues were investigated for additional information. The process and results of this study are meant to be a suggestion not only to further studies but also to artistic and creative shoe design. Originated for the functional purpose, shoes have evolved in various shapes with different meanings attached to it. When the technological development made the satisfaction for functional needs possible, the intrinsic attribute, the aesthetic value was pursued. The historical contemplations of shoes from Egyptian times to the 1990's led to the results that the intrinsic aesthetic value of shoes can be summarized as follows: 1) protection and extension of body, 2) need for decoration, 3) erotic expression, 4) symbol of dignity and class, 5) fashion.

This paper proposes a method to track persons robustly in illumination changes and partial occlusions in color video frames acquired from a fixed camera. To solve a problem of changing appearance by illumination change, a time-independent intrinsic image is used to remove noises in an frame and is adaptively updated frame-by-frame. We use a hierarchical human model including body color information in order to track persons in occlusion. The tracked human model is recorded into a persons' list for some duration after the corresponding person's exit and is recovered from the list after her reentering. The proposed method was experimented in several indoor and outdoor scenario. This demonstrated the potential effectiveness of an adaptive model-base method that corrected distorted person's color information by lighting changes, and succeeded tracking of persons which was overlapped in a frame.

Intraocular pressure is measured after a cornea air puff by observing biomechanical properties such as thickness or displacement of the cornea. In this paper, we deal with a frequency domain analysis of corneal deformation in the air puff tonometry that is used to diagnose glaucoma or lasik. We distinguish the patient from the normal by measuring the oscillation frequency in the neighborhood of the central cornea section. A binary image was obtained from the video images, and cornea vertical oscillation profile was extracted from the difference between the vertical displacement data and the curve fitting. In terms of Fourier transform, a vibration frequency of 479.2Hz for the patient was obtained as well as more higher 702.8Hz for the normal due to stiffness. Hilbert-Huang transform's empirical mode decomposition generally describes local, nonlinear, and nonstationary data. After the data were decomposed into intrinsic mode functions, a spectrum and power were analysed. Finally, we confirm that the patient has 6 times more higher power ratio for the specific intrinsic mode function between the patient and the normal.

A tele-operated robot should be used to maintain and inspect nuclear power plants to reduce the radiation exposure to the human operators. During an overhaul of the nuclear power plants in Korea, a ROV(Remotely Operated Vehicle) may enter a cold-leg connected to the reactor to examine the state of the thermal sleeve and it's position in the safety injection nozzle. To measure the positions of the thermal sleeve or scratches from the video images captured during the examination, the camera parameters should be identified. However, the focal length of the CCD camera could be increased to a close up of the target and the aspect ratio and the center of the image could also be varied with capturing devices. So, it is desired to self-calibrated the intrinsic parameters of the camera and capturing device with the video images captured during the examination. In the video image of the safety injection nozzle, two or more circular grooves around the nozzle are shown as ellipse contours. In this paper, we propose a camera self-calibration method using a single image containing two circular grooves which are the greatest circles of the cylindrical nozzle whose radius and distance are known.

General watermarking techniques tend not to consider intrinsic characteristics of image, so that watermarks are embeded to entire images. In this paper, we present a watermarking algorithm based on wavelet domain, and the watermark is embedded into large coefficients in region of interest(ROI) being based on principle of multi-threshold watermark coding(MTWC) for robust watermark insertion. We try to accomplish both image duality and robustness using human visual system(HVS). The watermarks are embedded in middle frequency bands because the distortion degree of watermarked images appears to be less than lower frequency bands, and the embedded watermarks in the middle bands showed high extraction ratios after some distortion. The watermarks are consisted of pseudo random sequences and detected using Cox's similarity mesurement.

Multimodal dual camera system has a stereo-like configuration equipped with an infrared thermal and optical camera. This paper presents stereo calibration methods on multimodal dual camera system using a target board that can be recognized by both thermal and optical camera. While a typical stereo calibration method usually performed with extracted intrinsic and extrinsic camera parameter, consecutive image processing steps were applied in this paper as follows. Firstly, the corner points were detected from the two images, and then the pixel error rate, the size difference, the rotation degree between the two images were calculated by using the pixel coordinates of detected corner points. Secondly, calibration was performed with the calculated values via affine transform. Lastly, result image was reconstructed with mapping regions on calibrated image.

In this study, the amount and frequency characteristics of cloud cavitation formed on a navy ship rudder were investigated through cavitation image processing technique and cavitation noise analysis. A high-speed camera with high time resolution was used to observe the cavitation on a full-spade rudder. The deflection angle range of the full-spade rudder was set to 8 to 15 degrees so that cloud cavitation was generated on the rudder surface. For images taken at 10⁴ fps (frame per second), reference values for detecting cavitation were defined and detected in Red, Green, Blue and Hue, Saturation, Lightness color spaces to quantitatively analyze the amount of cavitation. Intrinsic frequency characteristics of cloud cavitation were detected from the time series data of the amount of cavitation. The frequency characteristics of cloud cavitation obtained by using the image processing technique were found to be the same through the analysis of the noise signal measured by the hydrophone installed on the hull above the rudder, and its peak value was in the frequency band of 30~60Hz.

The aim of this research is to classify the concept expressed in the mobility of la diff${\acute{e}}$rant play, and supplement logic, which is process of the changeability of fashion style. The specific research questions are as follows: first question deals with the relationship between changeability and la diff${\acute{e}}$rant images, and how la diff${\acute{e}}$rant images are divided by each phase and how their circumduction play is proceeded. The second question is about the important features of the mobility of la diff${\acute{e}}$rant play and the method of la diff${\acute{e}}$rance play. The last topic of this study covers the supplement logic and the condition, and how supplement logic has been applied in the process of changeability of fashion style. This paper deploys a qualitative research method providing a systematic review of the previous studies. To sum it up, the mobility of la diff${\acute{e}}$rant play is the root of power, which is controlling the changeability of fashion style, and the objective of the play is to outline new la diff${\acute{e}}$rant images through spatialization of time. In addition, supplement logicis the method of la diff${\acute{e}}$rant play and the purpose of the logic is to harmonize 'ultimate la diff${\acute{e}}$rant image', which is the phenomenological construction stratum in the state of sub-conscious changeability, and 'immediate la diff${\acute{e}}$rant image', which is the structural construction level stratum in the state of external changeability. This research proves that the intrinsic attribute of changeability is contained the mobility of la diff${\acute{e}}$rant play and supplement logic.

This study analyzed the expression of hanbok in online fashion styling games, and examined the main themes of and user reactions to hanbok fashion styling games through semantic network analysis and sentiment analysis. KrKwic, Textom, and NodeXL were used for data collection and analysis. The findings of the study are as follows: First, depending on the designer's expressive method, hanbok fashion styling games provide typical traditional hanbok, modern hanbok, and dress-like fusion hanbok, demonstrating contents with various themes for different sexes, classes, and situations. Second, as a result of analyzing the themes of hanbok-related styling game contents, it turned out that the main themes are tradition, color, historical drama, fusion hanbok, holiday, and love. Most of them produce modernized hanbok that reflect the situation and utility rather than strictly traditional ones. Third, as a result of analyzing user reviews of hanbok styling game contents, positive factors mostly turned out to be the satisfaction of the hanbok contents, with the users also showing positive intent to wear hanbok. Through this, it was found out that hanboks portrayed in game contents could potentially cause the user's positive intent to wear hanbok. Negative factors turned out to be the discordance between the intrinsic image of hanbok and the game character's image.
