  • This study investigated how consumers perceive brand image, the consistency between the images of parent brands and extended brands, the consistency of their advertising images, the differences between brand image and advertising image, and how consumers' brand attitudes change based on those differences. An online survey was administered to women in their 20s and 30s who often use cosmetics and are interested in brands. The brands considered in this research were Chanel, Dior, Armani, and Anna Sui, which have extended brands in the clothing and cosmetics areas. In terms of consumers' perception of brand image, it was found that clothing and cosmetic brands were perceived similarly. In addition, significant differences were found in consumers' preferences and purchase intentions of clothing and cosmetic brands, and those whose perceptions of brand image did not change or increased after looking at advertising images had more positive brand attitudes than the group of people who had higher perception of brand image before looking at advertising images. Therefore, in terms of brand extension, it was revealed that the image of a parent brand affected an extended brand, and that the higher was consumers' recognition of brand image through advertising, the more positive was their attitude toward the brand.

  • Change detection technique is essential to various applications of Very High-Resolution(VHR) satellite imagery and land monitoring. However, change detection accuracy of VHR satellite imagery can be decreased due to various geometrical dissimilarity. In this paper, the existing fusion evaluation indexes were revised and applied to improve VHR imagery based change detection accuracy between multi-temporal images. In addition, appropriate change detection methodology of VHR images are proposed through comparison of general change detection algorithm with cross-sharpened image based change detection algorithm. For these purpose, ERGAS, UIQI and SAM, which were representative fusion evaluation index, were applied to unsupervised change detection, and then, these were compared with CVA based change detection result. Methodologies for minimizing the geometrical error of change detection algorithm are analyzed through evaluation of change detection accuracy corresponding to image fusion method, also. The experimental results are shown that change detection accuracy based on ERGAS index by using cross-sharpened images is higher than these based on other estimation index by using general fused image.

  • This paper presents an emotion recognition and its expression system of an intelligent robot like a home robot or a service robot. Emotion recognition method in the robot is used by a facial image. We use a motion and a position of many facial features. apply a tracking algorithm to recognize a moving user in the mobile robot and eliminate a skin color of a hand and a background without a facial region by using the facial region detecting algorithm in objecting user image. After normalizer operations are the image enlarge or reduction by distance of the detecting facial region and the image revolution transformation by an angel of a face, the mobile robot can object the facial image of a fixing size. And materialize a multi feature selection algorithm to enable robot to recognize an emotion of user. In this paper, used a multi layer perceptron of Artificial Neural Network(ANN) as a pattern recognition art, and a Back Propagation(BP) algorithm as a learning algorithm. Emotion of user that robot recognized is expressed as a graphic LCD. At this time, change two coordinates as the number of times of emotion expressed in ANN, and change a parameter of facial elements(eyes, eyebrows, mouth) as the change of two coordinates. By materializing the system, expressed the complex emotion of human as the avatar of LCD.

  • Purpose: The purpose of this study was to investigate the effects of group art therapy on old adults' powerlessness, loneliness. depression and self-image (for 55-year old or older people). Method: An experimental group of 10 persons were given group art therapy for 1 hour per week for 8 weeks. Results: The result of this study showed that group art therapy is effective in decreasing older adults' powerlessness (p<0.05) and their loneliness and depression (p<0.05). However, there was no significant difference in the score of loneliness (p>0.05). A tree test was executed to analyze self-image change. and the result of the tree test showed a significant change in the tree shape. which mean a significant positive change in self-image. Conclusions: The scores of older adults' powerlessness, loneliness and depression were lowered by the group art therapy. Therefore it is thought that group art therapy program was an effective intervention for improving older adults' quality of life. Thus, this study suggests to apply group art therapy as a supportive nursing intervention in order to manage powerlessness, loneliness, depression and self-image in old low-income adults.

  • To detect electrical faults of a TFT (Thin Film Transistor) panel for the LCD (Liquid Crystal Display), techniques of converting electric field to an image are used One of them is the PDLC (polymer-dispersed liquid crystal) modulator which changes light transmittance under electric field. The advantage of PDLC modulator in the electric field detection is that it can be used without physically contacting the TFT panel surface. Specific pattern signals are applied to the data and gate electrodes of the panel to charge the pixel electrodes and the image sensor detects the change of transmittance of PDLC positioned in proximity distance above the pixel electrodes. The image represents the status of electric field reflected on the PDLC so that the characteristic of the PDLC itself plays an important role to accurately quantify the defects of TFT panel. In this paper, the image of the PDLC modulator caused by the change of electric field of the pixel electrodes on the TFT panel is acquired and how the characteristics of PDLC reflect the change of electric field to the image is analyzed. When the holding time of PDLC is short, better contrast of electric field image can be obtained by changing the instance of applying the driving voltage to the PDLC.

  • The purpose of this study is to define the detailed factors related to expressing the aesthetic image of various baggy pants with changes to the hip circumference and crotch length ease. For this, detailed factors expressing the aesthetic image of baggy pants were deduced, and the aesthetic image and mutual influence according to the change in the hip circumference and crotch length ease were analyzed. Nine baggy pants with different levels of hip circumference and crotch length ease were produced as experimental pants. The image of each pair of experimental baggy pants was evaluated based on pictures taken of the pants worn by a woman in her 20s with a standard body figure. The image assessment team was composed of 105 clothing majors. The research results are as follows. Three aesthetic image factors of baggy pants were extracted: attractiveness, elegance and activity. When there was not much ease in the hip circumference and crotch length of the baggy pants, it appeared to look more attractive, younger and fashionable. A dignified and feminine image was perceived more when there was less ease in the hip circumference regardless of the crotch length. Because there was less ease in the hip circumference and crotch length, it appeared to be more comfortable, active and soft. These research results show that baggy pants with too much ease in the hip circumference or crotch length are perceived to be less attractive and actually as inactive. As seen here, there is a difference in the aesthetic image according to the change in the hip circumference and crotch length of the baggy pants; therefore, baggy pants which suits a person's own body type can be chosen to enhance the preferred aesthetic image of individuals.

  • This paper describes some results of change detection in Tokyo metropolitan area, Japan , using the Landsat TM data, and methods to quantify the ground cover classes. The changes are analyzed using the measures of not only conventional spectral classes but also a set of landscape indices to describe spatial properties of ground cove types using fractal dimension of objects, entropy in the specific windows defining the neighbors of focusing locations. In order eliminate the seasonal radiometric effects on TM data, an automated class labeling method is also attempted. Urban areas are also delineated automatically by defining the boundaries of the urban area. These procedures for urban change detection were implemented by the unified image computing methods proposed by the author, they can be automated in coherent and systematic ways, and it is anticipated to automate the whole procedures. The results of this analysis suggest that Tokyo metropolitan area was extended to the suburban areas along the new transportation networks and the high density area of Tokyo were also very much extended during the period between 1985 and 1995.
