  • This study was conducted to develop a basic pants pattern reflecting the average body shape of Chinese women in their 20s by using a virtual fitting method. A formula for the research pattern was derived by applying the measured value based on the drafting method of existing patterns. The final pattern was presented through two actual fitting processes. The suitability of the final pattern was then verified through a functional evaluation and an appearance evaluation based on an actual fitting and a virtual fitting. As a result of the evaluations, the final pattern reflected the body shape of Chinese women in their 20s and was evaluated as a higher quality pattern compared to existing patterns. The final pattern was based on the omphalion waist circumference. Ease amounts were set to be the omphalion waist circumference + 1.0 cm, hip circumference + 2.0 cm, and the pants length was set to 94 cm.

  • This study aimed to develop a fitted torso pattern with an improved fit for inverted-triangular males in their twenties. For this study, six torso patterns were collected, compared and evaluated, and a fitted torso pattern was developed using virtual fittings. The research results are as follows. First, the fitted torso pattern received a good rating as a result of the virtual fitting evaluation: waist dart set 2 of the front; the amount of comfort is set at 5 cm around the chest, 4 cm around the waist and 10 cm around the hips. Second, the evaluation of virtual fitting of the development pattern showed that fit evaluation was 4.11/5 points, ease evaluation was 6.53/7 points, and that the stress map and airgap were suitable for the human body. Third, the actual fit evaluation of the development pattern was 4.25/5 points, 6.35/7 points for ease evaluation, and 4.81/5 points for motion evaluation. Fourth, there was no significant difference between the results of the virtual and actual fitting evaluation with the objectivity test. It is therefore possible to apply a pattern developed through a virtual fitting to an actual human body and to confirm the objectivity of the pattern.

  • The study is designed to develop a educational basic pants patterns for men, and has been analyzed focusing on the university textbooks published since 2000. We also used CAD programs and virtual fitting programs to analyze the fitness of pants. To do this purpose, after choosing 7 Men's Wear textbooks, selected patterns were drawn and measured using PAD system and were compared and analyzed. Also, the appearance evaluation was examined through virtual fitting and then evaluated 21 male and female university students in their 20s. After supplementing the problems of the patterns in the existing textbooks, a pattern was developed and verified the fitness of the developed pattern. The results of comparing the proposed measurement items of each textbook for the pants pattern indicated a significant differences in terms of hip circumference of each pattern, which were between 96~105cm. A comparison of the drafting methods of each pattern showed the drafting methods for the crotch length, the front crotch extension, the back crotch extension were the difference. The results of appearance evaluation were pattern E presented the slimmest fit and pattern D presented the loosest fit. As a result of analysis of pants pattern, a waist circumference 82cm, a hip circumference 98cm, a crotch length 24cm, a pants length 104cm and a ham line width 46cm were most suitable. The development pattern was evaluated as superior to the existing pattern through the appearance evaluation of the virtual fitting.

  • The purpose of this study was conducted to improve middle and high school students' satisfaction on their uniforms and to provide basic information for their better size systems. This study analyzed the purchasing and modification behavior, fitting evaluation, and size decision aspect of students. This study was surveyed middle and high schools students in Daegu City. The collected data were analyzed by frequency analysis, percentage, t-test, chisquare test. The results of this study are as follows; 61.3% of the students interviewed have experienced to modify their uniforms. Since the unfittable size and non-fashionable design caused the students to modify their uniforms, it seems necessary to set up the various uniform sizes, as well as figuring out its aesthetic characteristic. Between middle school and high school students, and students with a uniform modification and students without a uniform modification, there were partially differences in fitting evaluation, and size decision.

  • The purpose of this study was to analyze the patterns of D level protective clothing, improve their ease of movement by modifying the patterns, and validate the effectiveness of the improvements through 3D virtual fitting and subjective wearing evaluations. Based on previous studies that identified numerous complaints, the patterns of the neck, armpit, and waist areas were modified, resulting in the development of new patterns. To compare and analyze the improved protective clothing with the basic protective clothing, stress and strain were examined after 3D virtual fitting. Additionally, to assess the clothing's allowance, the overall distance between the avatar and the protective clothing, as well as the sectional circumference length and distance of each avatar body part, were measured. Furthermore, the improved protective clothing was manufactured, and a subjective wearing evaluation was conducted with ten males in their twenties as participants. The results showed that the improved protective clothing had evenly distributed stress, larger sectional circumference, and lower average cavity distance. The subjective wearing evaluation also revealed that the suit with improved patterns exhibited superior size suitability, reduced pulling sensation in different body parts, and increased ease of movement. In conclusion, this study confirmed that even minimal pattern modifications can enhance the functionality of protective clothing, alleviating discomfort for wearers.

  • This study was undertaken to verify the effect of flow coefficient when a globe control valve was attached by different type of fitting. The valve flow coefficient is usually determined by measuring the flow rate and the pressure drop with the connection of straight pipe through the valve. The effect of different fitting that is mounted on the downstream of the valve is studied. Four types of fittings and three distances between the valve and a downstream fitting are compared parametrically to investigate the effect on the flow coefficient of it. Measured flow coefficient and numerically predicted value by using computational fluid dynamics were compared in detail. It is concluded that the flow coefficient is reduced if the fitting is attached after a valve, but the effect of different type of fitting is not crucial.

  • The purchase-related responses of MZ generation consumers may vary depending on the environmental factors of the fitting room. Therefore, this study extracted and systematized fitting room characteristics in the retail fashion environment. In-depth interviews were conducted with a total of 50 informants to collect data on the experience of using the fitting room. Then, a qualitative analysis was performed. First, results confirmed that the environmental factors of the fitting room include physical (spatiality, functionality, comfort, and convenience) and human (interactivity and congestion) aspects. Next, additional analysis was performed on functionality and interactivity to clarify the influence of environmental characteristics of the fitting room. These factors were classified into qualitative categories. The study results confirmed that, in the case of functionality, preferred lighting and mirror factors vary depending on the clothing product type, the place and situation for wearing, and individual characteristics. Furthermore, regarding interactivity, the preference for the presence of sales staff or companions differed according to personal traits and the need for additional information and evaluation. The study provides valuable information for effective fitting room space planning for offline fashion stores to meet the needs of MZ generation consumers.

  • Since correlation filter appeared in the field of object tracking, it plays an increasingly vital role due to its excellent performance. Although many sophisticated trackers have been successfully applied to track the object accurately, very few of them attaches importance to the scale and rotation estimation. In order to address the above limitation, we propose a novel method combined with Fourier-Mellin transform and confidence evaluation strategy for robust object tracking. In the first place, we construct a correlation filter to locate the target object precisely. Then, a log-polar technique is used in the Fourier-Mellin transform to cope with the rotation and scale changes. In order to achieve subpixel accuracy, we come up with an efficient surface fitting mechanism to obtain the optimal calculation result. In addition, we introduce a confidence evaluation strategy modeled on the output response, which can decrease the impact of image noise and perform as a criterion to evaluate the target model stability. Experimental experiments on OTB100 demonstrate that the proposed algorithm achieves superior capability in success plots and precision plots of OPE, which is 10.8% points and 8.6% points than those of KCF. Besides, our method performs favorably against the others in terms of SRE and TRE validation schemes, which shows the superiority of our proposed algorithm in scale and rotation evaluation.
