In most electronic imaging applications, image with high resolution(HR) are desired. HR means that pixel density within an image is high, and therefore HR image can offer more details that may be critical in various applications. Digital images that are captured by CCD and CMOS cameras usually have a very low resolution, which significantly limits the performance of image recognition systems. Image super-resolution techniques can be applied to overcome the limits of these imaging systems. Super-resolution techniques have been proposed to increase the resolution by combining information from multiple images. To techniques were consisted of the registration algorithm for estimation and shift, the nearest neighbor interpolation using weight of acquired frames and presented frames. In this paper, it is proposed the image interpolation techniques using the wavelet base function. This is applied to embody a correct edge image and natural image when expend part of the still image by applying the wavelet base function coefficient to the conventional Super-Resolution interpolation method. And the proposal algorithm in this paper is confirmed to improve the image applying the nearest neighbor interpolation algorithm, bilinear interpolation algorithm.,bicubic interpolation algorithm through the computer simulation.

This paper is related to a skinny smudge blending method using the arbitrary-shaped master adhered closely to the contour shape. The smudge tool is the popular graphic tool embedded in Adobe Photoshop CS6. The smudge tool is used to smear paint on your canvas. The effect is much like finger painting. We can use the smudge tool by selecting its icon on the toolbox of Adobe Photoshop CS6 and dragging in the direction you want to smudge while holding the mouse button down on the image. As the smudge tool blends all the pixels within a radius of the master to generate the result image, its disadvantages are to smudge even the pixels in the undesired region. In this paper to reduce the disadvantage, the skinny smudge blending method using arbitrary-shaped master is proposed. The proposed blending method has the advantage of applying the smudge effect to the desired regions regardless of the background as the arbitrary-shaped master adhered closely to the contour shape is extracted by color image segmentation.

This paper is related to a skinny smudge tool based on the image segmentation for a master shape. The smudge tool is the popular graphic tool embedded in Adobe Photoshop. The smudge tool is used to smear paint on your canvas. The effect is much like finger painting. You can use the smudge tool by clicking on the smudge icon and clicking on the canvas and while holding the mouse button down, dragging in the direction you want to smudge. A disadvantage of previous smudge tool is to also smear pixels in the undesired region according to generating the target image as blending all pixels in a diameter of the master. In this paper to reduce the disadvantage, the skinny smudge tool based on the image segmentation for a master shape is proposed. The proposed skinny smudge tool has the advantage of applying the smudge effect to the desired regions regardless of the background as the master shape adhered closely to the contour shape is extracted by color image segmentation.

This study was conducted to compare the body image perception, weight control experiences and the eating disorders according to where they were born, and the length of residence in USA among Korean-American college students. Three hundred college students participated in the study: 144 males and 156 females, 122 America-born (AB) and 171 Korea-born (KB) who live in New York City and New Jersey. Subjects responded to a self-administered questionnaire. The results showed that the ratio of overweight (23.2%) and obesity (26.8%) of males was higher than females'(16.1% and 6.3%, respectively). There were no significant differences according to born-place or the length of residence in USA of KB. People who had tried to control their weight were 58%. The ratio of weight control experiences of females (72.4%) was higher than males' (42.4%) as well as people who were normal or underweight than who were overweight or obesity. There were no significant differences according to born-place or the length of the residence in the USA of KB. In body image perception, the subjects who were normal and underweight overestimated their body figure, and the subjects who were overweight and obese underestimated their body figure. The desired and ideal figure of female students was significantly thinner than the current figure and also that of male students. There were no significant differences according to born-place or the length of the residence in USA of KB. The ratio of eating disorder was 8.7%, and females had higher percentage than males. And shorter they lived in USA, the percentage of eating disorder was higher.

In this paper, we propose a tube-hole center detection vision algorithm verifying the position of a tele-controlled robot and providing visual information for increasing reliability and efficiency in the diagnosis of steam generator (SG) tubes in nuclear power plant. A tele-controlled robot plays a role in carrying the probe used in inspecting the integrity of SG tubes. Thus accurately locating a tele-controlled robot on the desired tube-hole center is important issue for reliability of inspection. To do this work, we have to find the tube-hole center locations from the input image. At first, we apply the three-class segmentation method modified for this application. WE extract minimum bounding rectangles (MBRs) in the theresholded binary image. Second, for discriminating between MBR by tube and MBR by noise, we introduce the MBR rejection rules as knowledge-based rule set. MBRs are divided into the very dark region MBRs and the very bright region MBRs. In order to describe the region of complete tube-hole, the MBRs need a process of pairing each other. We then can find the tube-hole center from the paired MBR. For more accurately finding the tube-hole center in several sequential images, the centers of some frames need to be averaged. We tested the performance of our method using hundreds of real images.

Unsteady thermally stratified flow caused by two-dimensional surface discharge of warm water into a oblong channel was investigated. Experimental study was focused on the rapidly developing thermal diffusion at small Richardson number. The basic objective were to study the interfacial mixing between a flowing layer of warm water and an underlying body of cold water and to accumulate experimental data to test computational turbulence models. Mean velocity field measurements were carried out by using NMR-CT (Nuclear Magnetic Resonance-Computerized Tomography). It detects quantitative flow image of any desired section in any direction of flow in short time. Results show that at small Richardson number warm layer rapidly penetrates into the cold layer because of strong turbulent mixing and instability between the two layers. It is found that the transfer ofheat across the interface is more vigorous than that of momentum. It is also proved that the NMR-CT technique is a very valuable tool to measure unsteady three dimensional flow field.

This study conducted in-depth interviews with twelve men in their twenties and employed the Zaltman Metaphor Elicitation Technique (ZMET) to identify the ideal self-image and fantasy of men wearing makeup. The results are as follows. First, the ideal self-images of men wearing makeup can be divided into 7 images (well-managed, dissimilar from real identity, masculine, neat, stylish, standing out, and formal). Men who wear makeup pursued an alternative decent image that is different from their reality. They want to be manly, attractive, decorous, and eye-catching through a better looking face. Second, men who wear makeup have insecurities about their looks and personalities that creates dissatisfaction with reality and a desire for a different idealistic self. Makeup was the tool to create the other entity. Makeup facilitated a fantasy of becoming another to gain increased confidence in social relationships. However, without makeup, they showed a lack of confidence and became intimidated that made them even further dependent on makeup. Third, the process helped participants complete a consensus map that represented the emotional and reasoning structures of men wearing makeup. This study showed 7 ideal self-images of men wearing makeup with a fantasy to create a desired ideal self by wearing makeup. The study can be applied to marketing strategy for men's cosmetics and plates' designs.

In this paper, we propose a motion control scheme of robot manipulators based on visual feedback under camera-in-hand configuration. The desired joint velocity and acceleration for motion control is made by the feature-based visual data in the outer loop. The control input for tracking feature points on the image plane uses robot kinematics dynamic. The proposed control input consists of the image feature and the joint velocity error to achieve robustness to the parametric uncertainty. The stability of the closed-loop system is proved by Lyapunov approach. Computer simulations and experiments on a two degree of freedom manipulator with 5 links are presented to illustrate the performance of proposed control system.

As an electronic commerce grows in a rapid speed today, it has a great effect on not only our consuming lives but also the marketing activities. The study on involvement levels and consumer satisfaction in physical market in the existing studying papers in home was made progress rapidly. But, the study on involvement levels and consumer satisfaction in virtual market leaves much to be desired. This paper aims at considering the relationship between the involvement levels and the consumer satisfaction factors in the electronic commerce through the internet shopping mall whose importance is emphasized day by day. In this paper, three following questions were studied: (1) what is the difference among the factors(product/service/image) of consumer's satisfaction in accordance with consumers' involvement levels, (2) what is the difference in an intention of repurchase in accordance with the consumers' satisfaction factors, and (3) what is the difference in an intention of repurchase in accordance with the involvement levels and the consumers' satisfaction factors. As a result of analysis, only the service one of the factors of consumer's satisfaction has a difference in accordance with high/low involvement, and also, the factors which have an effect on the intention of repurchase were product, service and image.
