본 논문은 특징 클러스터에 대한 묘사에 기반한 새로운 특징 기반 영상 정합을 제안한다. 추출되는 특징들을 모두 동등하게 처리하는 기존 방법은 반복 패턴이 존재하는 영상에서는 매칭이 종종 실패하거나 적은 일치점만을 제공한다. 그 이유는 서로 닮아 있는 반복 패턴들로 인해 기하학적으로 일관되지 않은 매칭점들이 발생하거나 거리 비율 테스트를 통과하지 못하기 때문이다. 이에 반해 제안하는 방법은 더 많은 수의 일치점들을 발견할 수 있다. 이를 위해 제안하는 방법은 먼저 추출된 특징들을 반복 패턴으로부터 온 것들과 그렇지 않은 두드러진 특징들로 분리한다. 그런 후 support vector data description을 이용하여 각 반복 패턴들을 묘사한다. 동일하지 않은 영상이 매칭되는 경우를 제거하고 기하학적으로 일관된 일치점들을 제공하기 위해 매칭된 쌍에 대한 기하학적인 단서가 추가된다. 실험을 통해 제안하는 방법은 반복 패턴으로부터 추출된 특징들에 대해 일치점을 제공함으로써 더 많은 수의 일치점을 제공하게 되어 더 정확한 영상 정합을 수행한다는 것을 증명하였다.

The objectives of this study were to identify the dimensional structure of female impression formation based on ornaments and color of jacket, and to analyze the effect of ornaments, color of jacket, and perceiver's gender on impression formation. The experimental design was 3$\times$4$\times$2(ornaments$\times$color of jacket$\times$gender) factorial design by 3 independent variables. The stimuli of color photographs of female model and the semantic differential scale were used. Samples were 288 college males and females. The data were analyzed by factor analysis, ANOVA, duncan's multiple range test, and t-test. Four factors derived to account for the dimensions of impression formation. These were potency, elegance, evaluation, youthfulness, and feminine. Wearing of large ornaments(a necklace and earrings) had a negative effect on impression of elegance and positive on potency. Red jackets increased the impression of positive evaluation, potency, feminity, and youthfulness. On the jackets of achromatic color such as white and black, wearing of large ornaments increased the effect of potency, and large ornaments increased matured impression on black jacket. The results of this study mean that perceiverss used large ornaments and red jackets as a salient cue.

This study aims to characterize the sensibility image and interaction effect of striped necktie according to same-tone coordination and 1:2:3 area-ratio variation on the gender. The experimental materials developed for this study are a set of stimuli and response scales. The stimuli consist of 56 color pictures manipulated with every combination of 4 different colors, 2 different tones and 7 different area-ratio. The 7-point scale designed for visual evaluation of sensibility image included 26 bipolar adjectives. The subjects were 1344 undergraduate students in Gyeongnam, Seoul, Busan, and Daegu areas. The results of this study were as follows. The analyses of sensibility images in terms of same-tone coordination and 1:2:3 area-ratio variation of stripe necktie reveal that the concerned factors are of five characteristic dimensions of attractiveness, youth-activity, appeal, ability, and warmness. In the 5 factors of sensibility image, color combination and tone showed independent effect. In addition, significant interaction effects of area-ratio and tone on appeal and ability were found. Interaction effects of gender and area-ratio on youth-activity were found. Interaction effects of gender and tone on warmness were found. Interaction effects of color combination and tone on appeal and warmness were found. The study results are highly expected to be used as useful sources in developing men's coordination.

The purpose of this study was to investigate the sensibility image of necktie according to width and color combination of checked pattern. The experimental materials developed for this study were a set of stimulus and response scales. The stimuli were 18 color pictures, in which the width(small: 0.2cm, medium: 1cm, large: 2cm), tone combination(similar, contrast), and hue combination(WR: white+red, WB: white+blue, WG: white+gray) were manipulated. The 7-point scale was used for evaluation of sensibility image. The subjects of this research were 216 female college students living in Gyeongnam. The investigation was carried out at September 2009. The data were analyzed by using SPSS program. Analysis methods were ANOVA and Duncan-test. The results of this study were as follows.; The analyses of sensibility for necktie according to width and color combination of checked pattern revealed that the concerned factors are five characteristic dimensions of attractiveness, youth, appeal, elegance, and warmness. Width showed an independent effect on appeal. Tone combination showed an independent effect on attractiveness, appeal, elegance, and warmness. Interaction effects of width and tone combination on attractiveness were found. Hue combination showed an independent effect on all dimensions. In addition, significant interaction effects of width and hue combination on attractiveness, youth, appeal, and elegance were found. Significant interaction effects of tone combination and hue combination on attractiveness, youth, and appeal were found.
