In this paper, watermark embedding technique was proposed to securely conceal the watermark in color cover image by applying the spatial encryption technique. The embedded watermak can be extracted from stego-image without loss. The quality of the stego-image is very good. So it is not possible to visually distinguish the difference between the original cover image and the stego-image. The validity of the proposed technique was verified by mathematical analysis. The proposed watermark embedding technique can be used for intellectual property protection, military, and medical applications that require high security.

In this paper, we present an approach for matching images from finding interesting points and applying new image interpolation algorithm. New algorithms are developed that automatically align the input images match them and reconstruct 3-D surfaces. The interpolation algorithm is designed to cope with simple shapes. The proposed image interpolation algorithm generate a rotation image about vertical axes by an any angle from 4 base images. Each base image that was obtained from CCD camera has an angle difference of 90$^{\circ}$ The proposed image interpolation algorithm use the geometric analysis of image and depth information.

This study aimed to investigate the relationship between values orientation and fashion image orientation with a focus on the new senior generation. The study conducted data analysis by using the SPSS 17.0 program for the final 397 copies excluding incomplete questionnaires. The results of this study are as follows. First, values orientation was drawn as the four factors of social orientation, dependent orientation, family-like orientation, and individual orientation. The fashion image orientation was compartmentalized as three factors: urban image, individual image, and feminine image. Second, social orientation had a significant effect on feminine image as shown in Photo 1, while only individual orientation exerted a significant influence on individual image (Photo 2). Social orientation and family-like orientation respectively exercised a significant influence on individual image and feminine image, and feminine image (Photo 3). Third, the four groups did not show a significant difference in the relationship with the sub-elements of fashion image orientation. It appeared that all four groups were felt as a complex image in which modern, feminine, and individual images were mixed. Fourth, the four groups showed a significant difference in the unusual, elegant, refined, youthful, feminine, and modern images among the factors of fashion image orientation.

The purpose of this study was to investigate the difference of the visual evaluation about Clothing form and the surface image of detail. This study consists of pre-experiment for selecting the method of expression among detail which shows difference of the image and main experiment for identifying the clothing image as clothing form and the suface image of detial. Main experiment is made of factorial design for three variables-clothing form (H-line, A-line, V-line, X-line), detail (frill, tape), direction (width, length). Questionaire consists of 24 semantic differential scale expressing clothing form and detail. The subjects were 100 female students majoring in clothing and textile.7he data were analyzed by Frequencey, Factor analysis, Anova, scheffe's test and MCA method. The major findings were; 1) The image of clothing form and the surface image of detail were composed of 5 factors; attractiveness, prettiness, attention, modern, young. 2) For the visual evaluation of clothing form as the surface image of detail, there were significant differences in prettiness and attention factors. For the pretty and attentive image, we should express by the image of frill. 3) For the visual evaluation of the image of detail as clothing forms variation, there were significant difference in prettiness by A-line and X-line. 4) For the effect of clothing form and the surface image of detail, main effect was significant in attractiveness, prettiness, attention, modern factor. For the pretty image of clothing, it will be expressed by the image of frill and A-line, X-line. For the attentive image of clothing, it will be expressed by the image of frill and V-line. For the modern image of clothing, it will be expressed by the image of tape and V-line.

This day's research analyzed the difference between brand personality, self - image congruity, job satisfaction and their influences towards employees of family restaurants in order to suggest a plan which would induce researcher's interest as well as influencing diversification of management strategies toward dining-out business. The purpose of this research is to analyse the difference between brand personality, self - image congruity, job satisfaction and their influences towards employees of family restaurants. The survey questionnaires were distributed to 300 employees of family restaurants in Seoul from August 1th until August 30th 2009, and 257 of them were used for analysis. The top seven company's were chosen by base on data from 2009 Annual Dinner of the Korea. Statistics handling of this research used SPSS WIN 17.0 statistics package program, which performed frequency analysis, factor analysis, regrssion anlysis. The research result shows, first of all, the relationship between company's brand personality and personal self - image congruity, it shows that the company's brand personality has higher on 'ability/capability, loyalty/fidelity, and strong' the personal self - image congruity appeared higher. The relationship between company's brand personality and social self-image congruity, it shows that the company's brand personality has higher on 'ability/capability and loyalty/fidelity' the social self-image congruity appeared higher. Second of all, in a relation between the self-image congruity and job satisfaction, the personal self-image congruity has shown positive impact on job satisfaction. Third of all, in a relationship between the company's brand personality and job satisfaction, if 'interest or loyalty/fidelity' shows higher on brand personality, than job satisfaction has shown higher.

This paper aimed to investigate the difference of clothing behavior and desired image according to individualism-collectivism cultural tendency for women. A survey of 217 adult women was conducted from November to December 2006, mainly in Daegu. Reliability, frequency, percentage, factor analysis, ANOVA, t-test, Tukey test and an -analysis were used for data analysis by using SPSS WIN 11.0 package. The results were as follows: First, while the group with a higher tendency toward individualism valued personality and convenience above everything else, the group which has a higher tendency to collectivism disposition has a much greater interested in conformity and brand-orientation. Second, while the group with a higher tendency toward individualism pursued an bold image for their clothing, the group with a higher tendency toward collectivism preferred a feminine and plain image. Third, regarding the individualism-collectivism and demographic peculiarity, there were no significant differences between the two groups according to marital status and average monthly income. However, there were significant differences in individualism-collectivism among the groups determined by age, occupation, educational background and rural or urban background.

This paper presents an active ranging system based on laser structured-light image. The structured-light image processing is computationally efficient in comparison with the conventional stereo image processing, since the burdensome correspondence problem is avoidable. In order to achieve robustness against environmental illumination noise, an efficient image processing algorithm, i.e., integration of difference images with structured-light modulation is proposed. Distance equation from the measured structured light pixel distance and system parameter calibration are addressed in this paper. Experiments and analysis are carried out to verify performance of the proposed ranging system.

Image Mosaicing creates a new image by composing video frames or still images that are related, and performed by arrangement, composition and redundancy analysis of images. This paper proposes a hierarchical image mosaicing system using camera and object parameters far efficient video database construction. A tree-based image mosiacing has implemented for high-speed computation time and for construction of static and dynamic image mosaic. Camera parameters are measured by using least sum of squared difference and affine model. Dynamic object detection algorithm has proposed for extracting dynamic objects. For object extraction, difference image, macro block, region splitting and 4-split detection methods are proposed and used. Also, a dynamic positioning method is used for presenting dynamic objects and a blurring method is used for creating flexible mosaic image.
