This paper aimed at smartphone applications of department store brands in order to examine the traits of applications for the brand image. The study carried out survey research with 114 smartphone users who experienced the application of a department store, assuming that the design, contents, ease of use, and community characteristics of the application would affect satisfaction and the brand image. This paper performed a confirmatory factor analysis, correlation analysis, and the test of a model using PLS. Results showed that the design and contents of the application affected the improvement of satisfaction and of a brand image, whereas ease of use did not affect satisfaction and brand image. Also, community was influential on satisfaction, whereas it was not influential on the improvement of a brand image. Satisfaction with the application showed a strong impact on the improvement of a brand image; thus, it was found necessary for upcoming brand applications to enhance satisfaction for building a positive brand image.

The image identification methodology associates an image with a unique identifiable representation. Whenever the methodology regenerates an identifier for the same image, moreover, the newly created identifier needs to be consistent in terms of representation value. In this paper, we discuss a methodology for image identifier generation utilizing luminance correlation. We furthermore propose a method for performance enhancement of the image identifier generation. We also demonstrate the experimental evaluations for uniqueness and similarity analysis and performance improvement that have shown favorable results.

Images can be contaminated with different types of noise, for different reasons. The neighborhood averaging and smoothing by image averaging are the classical image processing techniques for noise removal. The classical spatial filtering refers to the aggregate of pixels composing an image and operating directly on these pixels. To reduce or remove effectively noise in image sequences, it usually needs to use noise reduction filter based on space or time domain such as method of spatial or temporal filter. However, the method of spatial filter can generally cause that signals of objects as the target are also blurred. In this paper, we propose temporal filter using the piece-wise quadratic function model and enhancement algorithm of image quality for the performance improvement of target detection and tracking by heterogeneous noise reduction. Image tracking simulation that utilizes real IIR(Imaging Infra-Red) images is employed to evaluate the performance of the proposed image processing algorithm.

Visibility in underwater images is usually poor because of the attenuation of light in the water that causes low contrast and color variation. In this paper, a new approach for underwater image quality improvement is presented. The proposed method aims to improve underwater image contrast, increase image details, and reduce noise by applying a new method of using contrast stretching to produce two different images with different contrasts. The proposed method integrates the modification of the image histogram in two main color models, RGB and HSV. The histograms of the color channel in the RGB color model are modified and remapped to follow the Rayleigh distribution within certain ranges. The image is then converted to the HSV color model, and the S and V components are modified within a certain limit. Qualitative and quantitative analyses indicate that the proposed method outperforms other state-of-the-art methods in terms of contrast, details, and noise reduction. The image color also shows much improvement.

This paper deals with image quality analysis considering the impact of psychological factors involved in assessment. The attributes of image quality requirement were partitioned according to the visual perception characteristics and the preference of image quality were obtained by the factor analysis method. The features of image quality which support the subjective preference were identified, The adequacy of image is evidenced to be the top requirement issues to the display image quality improvement.

In this paper, a particular application of digital photos, remote sensing, remote shooting air moving, high-resolution and high compression of medical images required by remote shooting of JPEG2000 standard applied in the field of hardware design, production was implemented. JPEG2000 standard for image compression using the software implementation of the processing speed is very slow compared to conventional JPEG disadvantages, and also the standard of JPEG2000 DWT (Discrete wavelet transform) to improve the level of compression for image data if processing speed is a phenomenon that has degraded. In order to solve these JPEG2000 compression / decompression groups were designed and applied. In this paper, the optimal JPEG2000 compression / reservoir hardware by changing the level for still image compression, faster computation speed and quality has shown improvement.

A consideration for image improvement under the Born approximation in the microwave diffraction tomography is suggested by using a projection function. The limiting factors in the degrading reconstructed image due to Born approximation are identified in terms of projection function and its modification is suggested to improve the degraded image based upon the Born approximation. In order to verify the proposed method, the reconstructed images are shown by computer simulation from the back-scattered data of angular and frequency diversity for squared dielectric cylinder with a various relative dielectric constant. From simulation results, it was shown that the proposed method can lead to a fairly good improved image for a severe degraded one irrespective of homogeneous and inhomogeneous dielectric object. In the future, the analysis on the limitation of this method should be considered and performed by means of more quantitative method.

The purpose of this study is to compare and analyze about the Telecasters's appearance management, external image & awareness on Self-Efficacy. The method of this study is carried out form 2 January 2013 until 20 January. with the 164 telecasters who announcers, voice actors, gag men, singers. The results of the research is summarized below: First, Among the telecasters, singer is the highest awareness of the beauty services importance about the fashion, makeup, hair, skin care, cosmetic surgery. Especially, about the awareness of the beauty services importance about the fashion, makeup, hair, singers> announcers> voice actors> gagmen appear one after another. Second, about the importance awareness of the beauty services importance & the relation of self-efficacy, for announcers, the more higher awareness the fashion, makeup, hair, the higher self-efficacy of the confidence, effective expression, etc.. For voice actors, the more higher awareness the hair, skin care, the fashion, make up, cosmetic surgery, the higher self-efficacy of the new image making, the confidence, task efficiency improvement, etc... For gagmen, the more higher awareness the fashion, hair, skin care, makeup, cosmetic surgery, the higher self-efficacy of the self-expression, the confidence, the new image making, task efficiency improvement, etc.. For singer, the more higher awareness the makeup, hair, cosmetic surgery, skin care, fashion, the higher self-efficacy of the task efficiency improvement, the self-expression, the confidence, the new image making, etc.. Third, about the importance awareness of the appearance management behavior, external image, about the importance awareness of the appearance management behavior, singer is the most higher awareness, announcers> voice actors> gagmen appear one after another. about the importance awareness of the external image, singer is the most higher awareness, voice actor> announcers> gagmen appear after another. The meanings of this study provide the telecasters's image's fields with the effective basic data.

This study was conducted to present basic improvement measures to improve the negative construction industry image of construction workers in the future, by investigating the construction industry images that construction workers have, through previous studies and analyzing the factors influencing these images, based on the multiple regression model. But this study is limited to construction workers and failed to establish specific improvement measures. Therefore, continued research which remedies the limitation of this study, will performed in the future.
