The purpose this study is to segments apparel market based on difference real-self image and ideal-self image. The objects of the study were to prepare for the establishment of marketing strategy and alternative plan intended to users which are needed in subdivided market, after analyzing according to what the subdivided market is divided into due to the difference real-self image and idea-self image and what difference do they show as a demographic special quality or as a general active special quality in each subdivided market. Factor analysis was performed to determine the leading difference real-self image and ideal-self image, and cluster analysis was employed to identify groups of respondents based on the delineated five image difference factors. Based on the finding, three distinct groups were formed: ideal-self image seeker group, moderators group, real-self image seeker group. And logistic regression was used to assess the relative importance that demographic characteristics play in determining the segmentation. The results of this study show statistically significant differences among the three groups in terms of demographic. Marketing and management implications for effectively targeting the segments are discussed.

The purpose of this study was to investigate the difference of visual evaluation about silhouette image. The specific objective were; 1) to construct of silhouette image evaluation instrument using semantic differential scale for the purpose of measuring the width and length; 2) to identify the factor structure of the silhouette; 3) to test the difference of visual perception to the silhouette as the variation of width; 4) to test the difference of visual perception to the silhouette as the variation of length; 5) to test interaction effect between width and length. The major finding were; For the visual evaluation of silhouette as shoulder width variatiorl, there were significant difference in hardness and softness factor. For the hard and soft image, we should express by variation of the shoulder width. For the visual evaluation of silhouette as skirt width variation, there were significant difference in attention factor. For the attensive image, we should express by variation of the skirt width. For the visual evaluation of silhouette as skirt length variation, there were significant difference in activity factor. For the active image, we should express by variation of the skirt length.

본 논문에서는 차영상 엔트로피 기반의 시선 인식 시스템을 제안한다. 차영상 엔트로피는 현재 입력된 영상과 참조 영상 또는 시선의 위치별 평균 영상들로부터 차영상을 획득하고, -255부터 +255까지의 히스토그램 빈도수를 이용하여 계산한다. 차영상 엔트로피 기반의 시선 인식방법은 2가지 방법이다. 1) 첫 번째 방법은 현재 입력된 영상과 시선 위치별 45개의 평균 영상들과의 차영상 엔트로피를 계산하여 현재 응시하고 있는 방향을 인식하고, 2) 두 번째 방법은 현재 입력된 영상과 45개의 참조 영상들과의 차영상 엔트로피를 계산하여 현재의 응시 방향을 인식한다. 참조 영상은 네 방향의 영상을 입력받아 시선 위치별 45개의 평균 영상을 이용하여 생성한다. 제안한 시스템의 성능을 평가하기 위해 PCA 기반의 시선 인식 시스템과 비교 실험을 하였고, 인식 방향은 좌상, 우상, 좌하, 우하 네 방향으로 하였으며, 45개의 참조 영상 또는 평균영상에 대하여 인식 영역을 변경하여 실험하였다. 실험 결과 차영상 엔트로피는 97.00%, PCA는 95.50%의 인식률을 보여 차영상 엔트로피 기반의 시스템이 PCA 기반의 시스템보다 1.50% 더 높은 인식률을 나타내었다.

In this paper, we propose a (2,2)-reversible secret image sharing scheme using histogram shifting and difference expansion. Two techniques are widely used in information hiding. Advantages of them are the low distortion between cover and stego images, and high embedding capacity. In secret image sharing procedure, unlike Shamir's secret sharing, a histogram generate that the difference value between the original image and copy image is computed by difference expansion. And then, the secret image is embedded into original and copy images by using histogram shifting. Lastly, two generated shadow images are distributed to each participant by the dealer. In the experimental results, we measure a capacity of a secret image and a distortion ratio between original image and shadow image. The results show that the embedding capacity and image distortion ratio of the proposed scheme are superior to the previous schemes.

이 논문에서는 영상시퀀스의 프레임간 차영상 블록을 영상활동도의 크기 및 분포에 따라 적응적으로 분류함으로써 영상시퀀스를 압축하는 기법을 제안한다. 활동도의 크기에 의한 분류에서는 차영상 블록에 포함되어 있는 물체의 에지부분에 해당하는 활동블록과 비활동 블록으로 분류하고, 활동도의 분포에 의한 분류에서도 활동블록들을 이산 코사인변환계수의 분포정도를 특징으로 하여 수직, 수평, 저활동 블록으로 분류한다. 대표적인 분류결과를 이용하여 RBFN 신경망을 학습시켜 프레임간 차영상 블록들의 비선형적인 분류 특성을 얻었다. 시뮬레이션 결과 RBFN을 이용한 차영상 블록의 분류가 영상활동도의 정렬방법이나 다층퍼셉트론 신경망(MLP)에 비해 영상시퀀스의 압축성능이 향상되었다.

Since digital images and videos are rapidly increasing in the internet with the spread of mobile computers and smartphones, research on image retrieval has gained tremendous momentum. Color, shape, and texture are major features used in image retrieval. Especially, color information has been widely used in image retrieval, because it is robust in translation, rotation, and a small change of camera view. This paper proposes a new method for histogram refinement based on local color difference. Firstly, the proposed method converts a RGB color image into a HSV color image. Secondly, it reduces the size of color space from 256³ to 32. It classifies pixels in the 32-color image into three groups according to the color difference between a central pixel and its neighbors in a 3x3 local region. Finally, it makes a color difference vector(CDV) representing three refined color histograms, then image retrieval is performed by the CDV matching. The experimental results using public image database show that the proposed method has higher retrieval accuracy than other conventional ones. They also show that the proposed method can be effectively applied to search low resolution images such as thumbnail images.

The purpose of this study was to evaluate the preference of image for modern application of Korean traditional patterns. A survey was conducted using the randomly selected 292 undergraduate women students of Taegu city. The degree of interest and preference in Korean traditional style or something like that had measured by 5 scale method. And then they had two groups which are interest/non-interest group, and preference/non-preference group in Korean traditional style. Also, preference of Korean traditional patterns was measured by 5 scale method. The image of Korean traditional patterns consisted of semantic differential scales. Analysis was by frequency, percentage, and mean. For difference of groups analysis was by t-test. The results were as follows:1. For the survey, 53.8% showed the interest and 40.4% did the preference for the traditional patterns. There was the positive correlation(0.782) between the degree of the interest and preference. 2. Among twenty traditional patterns, the patterns of plants and nature were very preferred, but the patterns of geometrical things was not preferred. 3. For the nature pattern, the image seemed to be elegant and feminine(womanly). For the plant pattern, the image seemed to be feminine, neat, weak, light and mild. For the animal pattern, the image seemed to be heavy, gorgeous, deluxe, virile(manly), strong and active. Last, for the geometrical pattern, the image seemed to be elegant, deluxe, rigid and strong. 4. Between the interest／non­interest groups, there was the significant difference in pattern of cloud, mountain, lotus flower, plum blossoms, orchid, dragon, chinese phoenix and bogy. Especially, for the orchid pattern, the preference difference between these groups was large. 5. For the plant pattern, the image difference between these groups was very large as the elegant-rustic image. Especially, the interest group evaluated as the elegant image. 6. Between the preference／non­preference groups, there was the strongly significant difference in the preference for the orchid pattern. 7. For the geometrical pattern, the image difference between these groups was very large as the mild­cold image. Especially, the preference groups evaluated as the cold image.
