This paper presents an algorithm for removing high-density impulsive noise that generates some serious distortions in edge regions of an image. Although many works have been presented to reduce edge distortions, these existing methods cannot sufficiently restore distorted edges in images with large amounts of impulsive noise. To solve this problem, this paper proposes a method using connected lines extracted from a binarized image, which segments an image into uniform and edge regions. For uniform regions, the existing simple adaptive median filter is applied to remove impulsive noise, and, for edge regions, a prediction filter and a line-weighted median filter using the connected lines are proposed. Simulation results show that the proposed method provides much better performance in restoring distorted edges than existing methods provide. When noise content is more than 20 percent, existing algorithms result in severe edge distortions, while the proposed algorithm can reconstruct edge regions similar to those of the original image.

This study is performed the design and production of the real hotel uniforms around the actual case. The purpose of the study is to research and develop the uniform design which is partially utilized for image integration. After reviewing and making up a theoretical background of general hotel uniforms, we designed I hotel's uniforms based on the uniform design process. Research Scope of uniform design is up to the development of it for practicians who have many opportunities to meet customers directly at front desk, banquet reservation office and restaurant. Based on logo of company C.I.(Corporate Identity) and symbol colors, the concept and an illustration according with I hotel are drawn up. Also design is planed and a real is produced. This like objective design development becomes the basis for building a uniform image suitable for C.I.(Corporate Identity) of hotel I and realizing a positive service. Also this study associated with the company would help the design development of corporate uniform.

Digital image recognition has been used for steel bridge surface assessment since late 1990s. However, the non-uniform illumination problems such as shades, shadows, and highlights are still challenges in image processing to date. Therefore, this paper develops a new approach to tackle the non-uniform illumination problem for rust image adjustment. The inhomogeneous illumination problem is divided into shades/shadows and highlights in this paper. The proposed BEMD-morphology approach (BMA) utilizes the bidimensional empirical mode decomposition to mitigate the shade/shadow effect, and the morphological processing to detect and replace the highlight area. Finally, the rust image processed with the BMA will be segmented by the K-Means algorithm, one of the most popular and effective methods, to show the effectiveness of illumination adjustment.

The purpose of this study was to examine whether uniform reforming behavior in high school girls is related to body image distortion, and to obtain objective data to help in guiding students in the wearing of uniforms at school. 661 freshmen and junior girls at six high schools in Kwangju city responded to questionnaires. The data was analyzed by one-way ANOVA and Pearson’s product-moment correlations using the SPSS 12.0 program. According to their body satisfaction level, three groups (haggard distortion, normal, overweight distortion) were identified. The data showed that a few high school girls were unable to recognize their body types correctly. It also indicated that school uniform reforming behaviors in high school girls were not related to their body image or body satisfaction level. So, it seems that students need guidance in the building up of an objective body image and wearing uniforms to fit their body types.

This study examines if the uniforms of dental hygienists influence the formation of professional identity. A self-administered survey was conducted on 534 dental hygienists in Seoul, Gyeonggi, and Incheon from March 28 to April 15, 2007. The dependent variable was professional identity. The independent variables were the organizational characteristics, uniform characteristics, and attitudes towards uniform. For the data analysis, we used t-test and hierarchical regression analysis. Using a t-test, we found the relationship between the color of the uniform and attitudes towards uniforms. The white uniform turned out to be associated with a positive perception of uniform function and uniform-image fit. The result of hierarchical regression analysis shows that the color of the uniform, perception of uniform functioning, and uniform satisfaction were statistically significant in predicting professional identity. We also tested the same model for two groups, those with and without image concern. The test results show that the significant factors were different for these two groups. This study confirms the function of uniforms in constructing professional identity and implies the need to have broader perspectives in studying uniforms.

Olympic uniforms emphasize aesthetics along with sports fashion trends and tendencies to display national competitiveness through colorful designs that use the national flag or colors as motifs. Korea needs to enhance the national brand through international sporting events such as the 2018 PyeongChang Olympic Games (30 years after the 1988 Seoul Olympic Games); therefore, a multilateral analysis is required to promote a global image of Korea. This study presents a development direction for more diverse national brand values for Korea through design research on Olympic uniforms. Research methods investigated the concepts and changes of the Geongongamli, and Taegeuk symbols as well as Olympic uniforms based on literature data and existing studies using uniforms. An Olympic uniform using symbols of the Korean flag was designed through a case analysis of Olympic uniform designs of countries that participated in the 2012 London Summer Olympic Games and 2014 Sochi Winter Olympic Games that reflect the countries' image. The research scope excluded uniforms for the actual games and limited the uniforms to official uniforms for the opening ceremony that represent the characteristics of each country; consequently, we analyzed 70 uniforms of 162 countries of the Winter Olympic Games. As a result, official national symbols were more frequently reflected than unofficial symbols in the uniform designs of the Summer and Winter Olympic Games with more frequencies of direct reflection than indirect reflection. Korea's national brand is expected to enhanced through a uniform that expresses Korea's image at international events and global exchanges.

The uniform motion blur removing algorithm of Cho et al. has the problem that the edge region of the image cannot be restored clearly. We propose the effective algorithm to overcome this problem by using shock filter that reconstructs a blurred step signal into a sharp edge, and convolutional neural network (CNN) that learns by extracting features from the image. Then uniform motion blur kernel is estimated from the latent sharp image to remove blur in the image. The proposed algorithm improved the disadvantages of the conventional algorithm by reconstructing the latent sharp image using shock filter and CNN. Through the experimental results, it was confirmed that the proposed algorithm shows excellent reconstruction performance in objective and subjective image quality than the conventional algorithm.

The variation of the electrical characteristics of thin-film transistors (TFTs) causes a non-uniform image quality problem, and the differential aging of organic light-emitting diode (OLED) devices causes an image-sticking problem. A video data correction method is proposed herein as an effective solution to the non-uniform electro-optical characteristics of the pixels in activematrix organic light-emitting diode (AMOLED) displays. The results of the simulation that was conducted show that the proposed method successfully senses the electrical characteristics of TFTs and the degradation of OLEDs and effectively compensates for them.

In this work we propose a compression technique that makes use of linear and perceptually uniform CIE $La^*b^*$ color space in the JPEG image compression framework to improve its performance at lower bitrates. To generate quantization matrices suitable for the linear and perceptually uniform CIE $La^*b^*$ color space, a novel linear Contrast Sensitivity Function (CSF) is used. The compression performance in terms of Compression Ratio (CR) and Peak Signal to Noise Ratio (PSNR), is further improved by utilizing image dependent, variable and non-uniform image sub-blocks generated using a proposed histogram-based merging technique. Experimental results indicate that the proposed linear CSF based quantization technique yields, on an average, 8% increase in CR for the same reconstructed image quality in terms of PSNR as compared to the conventional YCbCr color space. The proposed scheme also outperforms JPEG in terms of CR by an average of 45.01% for the same reconstructed image quality.
